Restart oVirt-Engine

How ,without reboot of hosting system, do I restart the oVirt engine? # I tried below but do not seem to effect the virtual machine [root@thor iso]# systemctl restart ov ovirt-ha-agent.service ovirt-imageio.service ovn-controller.service ovs-delete-transient-ports.service ovirt-ha-broker.service ovirt-vmconsole-host-sshd.service ovsdb-server.service ovs-vswitchd.service [root@thor iso]# # You cannot restart the VM " HostedEngine " as it responses: Error while executing action: HostedEngine: - Cannot restart VM. This VM is not managed by the engine. Reason is I had to do some work on a node. Reboot it.. it is back up.. network is all fine.. Cockpit working fine... and gluster fine.. But oVirt-Engine refuses to accept the node is up. -- p <jeremey.wise(a)gmail.com>enguinpages

SPM and Task error ...
by Enrico 22 Nov '24

22 Nov '24

Hi all, my ovirt cluster has got 3 Hypervisors runnig Centos 7.5.1804 vdsm is 4.20.39.1-1.el7, ovirt engine is 4.2.4.5-1.el7, the storage systems are HP MSA P2000 and 2050 (fibre channel). I need to stop one of the hypervisors for maintenance but this system is the storage pool manager. For this reason I decided to manually activate SPM in one of the other nodes but this operation is not successful. In the ovirt engine (engine.log) the error is this: 2019-07-25 12:39:16,744+02 INFO [org.ovirt.engine.core.bll.storage.pool.ForceSelectSPMCommand] (default task-30) [7c374384-f884-4dc9-87d0-7af27dce706b] Running command: ForceSelectSPMCommand internal: false.

Changing disk QoS causes segfault with IO-Threads enabled (oVirt 4.3.0.4-1.el7)
by jloh＠squiz.net 23 Apr '24

23 Apr '24

We recently upgraded to 4.3.0 and have found that when changing disk QoS settings on VMs whilst IO-Threads is enabled causes them to segfault and the VM to reboot. We've been able to replicate this across several VMs. VMs with IO-Threads disabled/turned off do not segfault when changing the QoS. Mar 1 11:49:06 srvXX kernel: IO iothread1[30468]: segfault at fffffffffffffff8 ip 0000557649f2bd24 sp 00007f80de832f60 error 5 in qemu-kvm[5576498dd000+a03000] Mar 1 11:49:06 srvXX abrt-hook-ccpp: invalid number 'iothread1' Mar 1 11:49:11 srvXX libvirtd: 2019-03-01 00:49:11.116+0000: 13365: error : qemuMonitorIORead:609 : Unable to read from monitor: Connection reset by peer Happy to supply some more logs to someone if they'll help but just wondering whether anyone else has experienced this or knows of a current fix other than turning io-threads off. Cheers.

https://bugzilla.redhat.com/show_bug.cgi?id=1472356 There are 2 drives in my install that oVirt is claiming as multipath. I have tried blacklisting at /etc/multipath/ but that hasn't worked. Any better solutions? I need these 2 drives to be non-multipathed.

Network Address Change
by Paul.LKW 28 Dec '22

28 Dec '22

Hi All: I just has a case, I need to change the oVirt host and engine IP address due to data center decommission I checked in the hosted-engine host there are some files I could change ; in ovirt-hosted-engine/hosted-engine.conf ca_subject="O=simple.com, CN=1.2.3.4" gateway=1.2.3.254 and of course I need to change the ovirtmgmt interface IP too, I think just change the above line could do the tick, but where could I change the other host IP in the cluster ? I think I have to be lost all the host as once changed the hosted-engine host IP as it is in diff. sub net. Does there any command line tools could do that or someone has such experience could share? Best Regards, Paul.LKW

looking for some ISV backup software which integrates the backup API
by Nathanaël Blanchet 08 Jun '22

08 Jun '22

Hello, We are about to change our backup provider, and I find it is a great chance to choose a full supported ovirt backup solution. I currently use this python script vm-backup-scheduler (https://github.com/wefixit-AT/oVirtBackup) but it is not the workflow officially suggested by the community (https://www.ovirt.org/develop/release-management/features/storage/backup-re…) I've been looking for a long time an ISV who supports such an API, but the only one I found is this one : Acronis Backup Advanced suggested here https://access.redhat.com/ecosystem/search/#/ecosystem/Red%20Hat%20Enterpri… I ran the trial version, but it doesn't seem to do better than the vm-backup-scheduler script, and it doesn't seem to use the backup API (attach a clone as a disk to an existing vm). Can you suggest me some other ISV solutions, if they ever exist... or share me your backup experience?

VM HostedEngine is down with error
by souvaliotimaria＠mail.com 26 May '22

26 May '22

Hello everyone, I have a replica 2 + arbiter installation and this morning the Hosted Engine gave the following error on the UI and resumed on a different node (node3) than the one it was originally running(node1). (The original node has more memory than the one it ended up, but it had a better memory usage percentage at the time). Also, the only way I discovered the migration had happened and there was an Error in Events, was because I logged in the web interface of ovirt for a routine inspection. Βesides that, everything was working properly and still is. The error that popped is the following: VM HostedEngine is down with error. Exit message: internal error: qemu unexpectedly closed the monitor: 2020-09-01T06:49:20.749126Z qemu-kvm: warning: All CPU(s) up to maxcpus should be described in NUMA config, ability to start up with partial NUMA mappings is obsoleted and will be removed in future 2020-09-01T06:49:20.927274Z qemu-kvm: -device virtio-blk-pci,iothread=iothread1,scsi=off,bus=pci.0,addr=0x7,drive=drive-ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,id=ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2,bootindex=1,write-cache=on: Failed to get "write" lock Is another process using the image?. Which from what I could gather concerns the following snippet from the HostedEngine.xml and it's the virtio disk of the Hosted Engine: <disk type='file' device='disk' snapshot='no'> <driver name='qemu' type='raw' cache='none' error_policy='stop' io='threads' iothread='1'/> <source file='/var/run/vdsm/storage/80f6e393-9718-4738-a14a-64cf43c3d8c2/d5de54b6-9f8e-4fba-819b-ebf6780757d2/a48555f4-be23-4467-8a54-400ae7baf9d7'> <seclabel model='dac' relabel='no'/> </source> <target dev='vda' bus='virtio'/> <serial>d5de54b6-9f8e-4fba-819b-ebf6780757d2</serial> <alias name='ua-d5de54b6-9f8e-4fba-819b-ebf6780757d2'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/> </disk> I've tried looking into the logs and the sar command but I couldn't find anything to relate with the above errors and determining the reason for it to happen. Is this a Gluster or a QEMU problem? The Hosted Engine was manually migrated five days before on node1. Is there a standard practice I could follow to determine what happened and secure my system? Thank you very much for your time, Maria Souvalioti

Is it possible to setup a hosted engine using the OVS switch type instead of Legacy? If it's not possible to start out as OVS, instructions for switching from Legacy to OVS after the fact would be greatly appreciated. Many thanks, Devin

USB3 redirection
by Rik Theys 19 Apr '22

19 Apr '22

Hi, I'm trying to assign a USB3 controller to a CentOS 7.4 VM in oVirt 4.1 with USB redirection enabled. I've created the following file in /etc/ovirt-engine/osinfo.conf.d: 01-usb.properties with content os.other.devices.usb.controller.value = nec-xhci and have restarted ovirt-engine. If I disable USB-support in the web interface for the VM, the xhci controller is added to the VM (I can see it in the qemu-kvm commandline), but usb redirection is not available. If I enable USB-support in the UI, no xhci controller is added (only 4 uhci controllers). Is there a way to make the controllers for usb redirection xhci controllers? Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept.

OVN routing and firewalling in oVirt
by Gianluca Cecchi 19 Apr '22

19 Apr '22

Hello, how do we manage routing between different OVN networks in oVirt? And between OVN networks and physical ones? Based on architecture read here: http://openvswitch.org/support/dist-docs/ovn-architecture.7.html I see terms for logical routers and gateway routers respectively but how to apply to oVirt configuration? Do I have to choose between setting up a specialized VM or a physical one: is it applicable/advisable to put on oVirt host itself the gateway functionality? Is there any security policy (like security groups in Openstack) to implement? Thanks, Gianluca

Host needs to be reinstalled after configuring power management
by Andrew DeMaria 02 Feb '22

02 Feb '22

Hi, I am running ovirt 4.3 and have found the following action item immediately after configuring power management for a host: Host needs to be reinstalled as important configuration changes were applied on it. The thing is - I've just freshly installed this host and it seems strange that I need to reinstall it. Is there a better way to install a host and configure power management without having to reinstall it after? Thanks, Andrew

Import an exported VM using Ansible
by paolo＠airaldi.it 25 Jan '22

25 Jan '22

Hello everybody! I'm trying to automate a copy of a VM from one Datacenter to another using an Ansible.playbook. I'm able to: - Create a snapshot of the source VM - create a clone from the snapshot - remove the snapshot - attach an Export Domain - export the clone to the Export Domain - remove the clone - detach the Export domain from the source Datacenter and attach to the destination. Unfortunately I cannot find a module to: - import the VM from the Export Domain - delete the VM image from the Export Domain. Any hint on how to do that? Thanks in advance. Cheers. Paolo PS: if someone is interested I can share the playbook.

Hello everyone. I would like to know how disk size and snapshot allocation works, because every time I create a new snapshot, it increases 1 GB in the VM's disk size, and when I remove the snap, that space is not returned to Domain Storage. I'm using the oVirt 4.3.10 How do I reprovision the VM disk? Thank you all.

Template for Ubuntu 18.04 Server Issues
by jeremy_tourville＠hotmail.com 02 Sep '21

02 Sep '21

I have built a system as a template on oVirt. Specifically, Ubuntu 18.04 server. I am noticing an issue when creating new vms from that template. I used the check box for "seal template" when creating the template. When I create a new Ubuntu VM I am getting duplicate IP addresses for all the machines created from the template. It seems like the checkbox doesn't fully function as intended. I would need to do further manual steps to clear up this issue. Has anyone else noticed this behavior? Is this expected or have I missed something? Thanks for your input!

I have recently enabled it and have noticed a significant (over 4x) increase in io performance on my vms. I’m concerned however since it does not seem to be an ovirt default setting. Is libgfapi considered safe and stable to use in ovirt 4.3 hci?

supervdsm failing during network_caps

Hi, I have issues with one host where supervdsm is failing in network_caps. I see the following trace in the log. MainProcess|jsonrpc/1::ERROR::2020-01-06 03:01:05,558::supervdsm_server::100::SuperVdsm.ServerCallback::(wrapper) Error in network_caps Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/supervdsm_server.py", line 98, in wrapper res = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/network/api.py", line 56, in network_caps return netswitch.configurator.netcaps(compatibility=30600) File "/usr/lib/python2.7/site-packages/vdsm/network/netswitch/configurator.py", line 317, in netcaps net_caps = netinfo(compatibility=compatibility) File "/usr/lib/python2.7/site-packages/vdsm/network/netswitch/configurator.py", line 325, in netinfo _netinfo = netinfo_get(vdsmnets, compatibility) File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/cache.py", line 150, in get return _stringify_mtus(_get(vdsmnets)) File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/cache.py", line 59, in _get ipaddrs = getIpAddrs() File "/usr/lib/python2.7/site-packages/vdsm/network/netinfo/addresses.py", line 72, in getIpAddrs for addr in nl_addr.iter_addrs(): File "/usr/lib/python2.7/site-packages/vdsm/network/netlink/addr.py", line 33, in iter_addrs with _nl_addr_cache(sock) as addr_cache: File "/usr/lib64/python2.7/contextlib.py", line 17, in __enter__ return self.gen.next() File "/usr/lib/python2.7/site-packages/vdsm/network/netlink/__init__.py", line 92, in _cache_manager cache = cache_allocator(sock) File "/usr/lib/python2.7/site-packages/vdsm/network/netlink/libnl.py", line 469, in rtnl_addr_alloc_cache raise IOError(-err, nl_geterror(err)) IOError: [Errno 16] Message sequence number mismatch A restart of supervdsm will resolve the issue for a period, maybe 24 hours, then it will occur again. So I'm thinking it's resource exhaustion or a leak of some kind? Running 4.2.8.2 with VDSM at 4.20.46. I've had a look through the bugzilla and can't find an exact match, closest was this one https://bugzilla.redhat.com/show_bug.cgi?id=1666123 which seems to be a RHV only fix. Thanks, Alan

OVN and change of mgmt network
by Gianluca Cecchi 27 Jan '21

27 Jan '21

Hello, I previously had OVN running on engine (as OVN provider with northd and northbound and southbound DBs) and hosts (with OVN controller). After changing mgmt ip of hosts (engine has retained instead the same ip), I executed again on them the command: vdsm-tool ovn-config <ip_of_engine> <nel_local_ip_of_host> Now I think I have to clean up some things, eg: 1) On engine where I get these lines below systemctl status ovn-northd.service -l . . . Sep 29 14:41:42 ovmgr1 ovsdb-server[940]: ovs|00005|reconnect|ERR|tcp: 10.4.167.40:37272: no response to inactivity probe after 5 seconds, disconnecting Oct 03 11:52:00 ovmgr1 ovsdb-server[940]: ovs|00006|reconnect|ERR|tcp: 10.4.167.41:52078: no response to inactivity probe after 5 seconds, disconnecting The two IPs are the old ones of two hosts It seems that a restart of the services has fixed... Can anyone confirm if I have to do anything else? 2) On hosts (there are 3 hosts with OVN on ip 10.4.192.32/33/34) where I currently have this output [root@ov301 ~]# ovs-vsctl show 3a38c5bb-0abf-493d-a2e6-345af8aedfe3 Bridge br-int fail_mode: secure Port "ovn-1dce5b-0" Interface "ovn-1dce5b-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.32"} Port "ovn-ddecf0-0" Interface "ovn-ddecf0-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.33"} Port "ovn-fd413b-0" Interface "ovn-fd413b-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.168.74"} Port br-int Interface br-int type: internal ovs_version: "2.7.2" [root@ov301 ~]# The IPs of kind 10.4.192.x are ok. But there is a left-over of an old host I initially used for tests, corresponding to 10.4.168.74, that now doesn't exist anymore How can I clean records for 1) and 2)? Thanks, Gianluca

CentOS Stream support
by Michal Skrivanek 25 Jan '21

25 Jan '21

Hi all, we would like to ask about interest in community about oVirt moving to CentOS Stream. There were some requests before but it’s hard to see how many people would really like to see that. With CentOS releases lagging behind RHEL for months it’s interesting to consider moving to CentOS Stream as it is much more up to date and allows us to fix bugs faster, with less workarounds and overhead for maintaining old code. E.g. our current integration tests do not really pass on CentOS 8.1 and we can’t really do much about that other than wait for more up to date packages. It would also bring us closer to make oVirt run smoothly on RHEL as that is also much closer to Stream than it is to outdated CentOS. So..would you like us to support CentOS Stream? We don’t really have capacity to run 3 different platforms, would you still want oVirt to support CentOS Stream if it means “less support” for regular CentOS? There are some concerns about Stream being a bit less stable, do you share those concerns? Thank you for your comments, michal

encrypted GENEVE traffic
by Pavel Nakonechnyi 18 Jan '21

18 Jan '21

Dear oVirt Community, From my understanding oVirt does not support Open vSwitch IPSEC tunneling for GENEVE traffic (which is described on pages http://docs.openvswitch.org/en/latest/howto/ipsec/ and http://docs.openvswitch.org/en/latest/tutorials/ipsec/) Are there plans to introduce such support? (or explicitly not to..) Is it possible to somehow manually configure such tunneling for existing virtual networks? (even in a limited way) Alternatively, is it possible to deploy oVirt on top of the tunneled (i.e. via VXLAN, IPSec) interfaces? This will allow to encrypt all management traffic. Such requirement arises when using oVirt deployment on third-party premises with untrusted network. Thank in advance for any clarifications. :) -- WBR, Pavel +32478910884

oVirt 4.4: Self-hosted engine deployment fails with backup restore from 4.3 engine
by Oliver Leinfelder 11 Dec '20

11 Dec '20

Hi there, I'm a bit puzzled about an possible upgrade paths from a 4.3 cluster to version 4.4 in a self-hosted engine environment. My idea was: Set up a new host with a clean ovirt node 4.4 installation, then deploy the hosted engine on this with a restored backup from the production cluster and go from there. This however fails with the following error: 2020-05-27 00:17:08,886+0200 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:103 {'msg': 'non-zero return code', 'cmd': ['engine-setup', '--accept-defaults', '--config-append=/root/ovirt-engine-answers'], 'stdout': "[ INFO ] Stage: Initializing\n[ INFO ] Stage: Environment setup\n C onfiguration files: /etc/ovirt-engine-setup.conf.d/10-packaging-jboss.conf, /etc/ovirt-engine-setup.conf.d/10-packaging.conf, /etc/ovirt-engine-setup.conf.d/20-setup-ovirt-post.conf, /root/ovirt-engine-answers\n Log file: /var/log/ovirt-engine/setup/ovirt-engine-setup-20200527001657-fyeueu.log\n Version: otop i-1.9.1 (otopi-1.9.1-1.el8)\n[ INFO ] DNF Downloading 1 files, 0.00KB\n[ INFO ] DNF Downloaded CentOS-8 - AppStream\n[ INFO ] DNF Downloading 1 files, 0.00KB\n[ INFO ] DNF Downloaded CentOS-8 - Base\n[ INFO ] DNF Downloading 1 files, 0.00KB\n [...] ... anwsers from backup config follow ....

"gluster-ansible-roles is not installed on Host" error on Cockpit
by Hesham Ahmed 26 Nov '20

26 Nov '20

On a new 4.3.1 oVirt Node installation, when trying to deploy HCI (also when trying adding a new gluster volume to existing clusters) using Cockpit, an error is displayed "gluster-ansible-roles is not installed on Host. To continue deployment, please install gluster-ansible-roles on Host and try again". There is no package named gluster-ansible-roles in the repositories: [root@localhost ~]# yum install gluster-ansible-roles Loaded plugins: enabled_repos_upload, fastestmirror, imgbased-persist, package_upload, product-id, search-disabled-repos, subscription-manager, vdsmupgrade This system is not registered with an entitlement server. You can use subscription-manager to register. Loading mirror speeds from cached hostfile * ovirt-4.3-epel: mirror.horizon.vn No package gluster-ansible-roles available. Error: Nothing to do Uploading Enabled Repositories Report Cannot upload enabled repos report, is this client registered? This is due to check introduced here: https://gerrit.ovirt.org/#/c/98023/1/dashboard/src/helpers/AnsibleUtil.js Changing the line from: [ "rpm", "-qa", "gluster-ansible-roles" ], { "superuser":"require" } to [ "rpm", "-qa", "gluster-ansible" ], { "superuser":"require" } resolves the issue. The above code snippet is installed at /usr/share/cockpit/ovirt-dashboard/app.js on oVirt node and can be patched by running "sed -i 's/gluster-ansible-roles/gluster-ansible/g' /usr/share/cockpit/ovirt-dashboard/app.js && systemctl restart cockpit"

ovirt-imageio-proxy not working after updating SSL certificates with a wildcard cert issued by AlphaSSL (intermediate)
by Lynn Dixon 22 Nov '20

22 Nov '20

All, I recently bought a wildcard certificate for my lab domain (shadowman.dev) and I replaced all the certs on my RHV4.3 machine per our documentation. The WebUI presents the certs successfully and without any issues, and everything seemed to be fine, until I tried to upload a disk image (or an ISO) to my storage domain. I get this error in the events tab: https://share.getcloudapp.com/p9uPvegx [image: image.png] I also see that the disk is showing up in my storage domain, but its showing "Paused by System" and I can't do anything with it. I cant even delete it! I have tried following this document to fix the issue, but it didn't work: https://access.redhat.com/solutions/4148361 I am seeing this error pop into my engine.log: https://pastebin.com/kDLSEq1A And I see this error in my image-proxy.log: WARNING 2020-07-24 15:26:34,802 web:137:web:(log_error) ERROR [172.17.0.30] PUT /tickets/ [403] Error verifying signed ticket: Invalid ovirt ticket (data='------my_ticket_data-----', reason=Untrusted certificate) [request=0.002946/1] Now, when I bought my wildcard, I was given a root certificate for the CA, as well as a separate intermediate CA certificate from the provider. Likewise, they gave me a certificate and a private key of course. The root and intermediate CA's certificates have been added to /etc/pki/ca-trust/source/anchors/ and I did an update-ca-trust. I also started experiencing issues with the ovpn network provider at the same time I replaced the SSL certs, but I disregarded it at the time, but now I am thinking its related. Any advice on what to look for to fix the ovirt-imageio-proxy?

Single Node HCI upgrade procedure from CentOS7/oVirt 4.3 to CentOS8/oVirt 4.4?
by thomas＠hoberg.net 11 Nov '20

11 Nov '20

I can hear you saying: "You did understand that single node HCI is just a toy, right?" For me the primary use of a single node HCI is adding some disaster resilience in small server edge type scenarios, where a three node HCI provides the fault tolerance: 3+1 with a bit of distance, warm or even cold stand-by, potentially manual switch and reduced workload in case disaster strikes. Of course, another 3nHCI would be better, but who gets that type of budget, right? What I am trying say: If you want oVirt to gain market share, try to give HCI more love. And while you're at it, try to make expanding from 1nHCI to 3nHCI (and higher counts) a standard operational procedure to allow expanding a disaster stand-by into a production setup, while the original 3nHCI is being rebuilt. For me low-budget HCI is where oVirt has its biggest competitive advantage against vSan and Nutanix, so please don't treat the HCI/gluster variant like an unwanted child any more. In the mean-time OVA imports (from 4.3.10 exports) on my 4.4.2 1nHCI fail again, which I'll report separately.

Problem with Cluster-wise BIOS Settings in oVirt 4.4
by Rodrigo G. López 11 Nov '20

11 Nov '20

Hi all, We are running an oVirt 4.4 Hosted Engine as a VM, and after changing the Cluster's BIOS type from Q35 with Legacy BIOS (the default one after installation) to Preexistent, the VM fails with the following error: XML error: The device at PCI address 0000:00:02.0 cannot be plugged into the PCI controller with index='0'. It requires a controller that accepts a pcie-root-port. We need it so that we can run imported VMs from a previous version of oVirt, namely 4.0. Applying the BIOS settings individually works but as an attempt to generalize the settings we decided to apply it to the full cluster. Tell me if you need more data. Cheers, -rodri

POWER9 (ppc64le) Support on oVirt 4.4.1
by Vinícius Ferrão 03 Nov '20

Hello, I was using oVirt 4.3.10 with IBM AC922 (POWER9 / ppc64le) without any issues. Since I’ve moved to 4.4.1 I can’t add the AC922 machine to the engine anymore, it complains with the following error: The host CPU does not match the Cluster CPU type and is running in degraded mode. It is missing the following CPU flags: model_POWER9, powernv. Any ideia of what’s may be happening? The engine runs on x86_64, and I was using this way on 4.3.10.

adminstration portal wont complete load, looping

I have an odd situation: When I go to https://ovengine/ovirt-engine/webadmin/?locale=en_US after authentication passes... it shows the top banner of oVirt OPEN VIRTUALIZATION MANAGER and the Loading ... in the center. but never gets past that. Any suggestions on how I could investigate and fix this? background: I recently updated certs to be signed wildcard certs, but this broke consoles somehow. So I restored the original certs, and restarted things... but got stuck with this. Interestingly, the VM portal loads fine.

Latest ManagedBlockDevice documentation
by Michael Thomas 15 Oct '20

15 Oct '20

I'm looking for the latest documentation for setting up a Managed Block Device storage domain so that I can move some of my VM images to ceph rbd. I found this: https://ovirt.org/develop/release-management/features/storage/cinderlib-int… ...but it has a big note at the top that it is "...not user documentation and should not be treated as such." The oVirt administration guide[1] does not talk about managed block devices. I've found a few mailing list threads that discuss people setting up a Managed Block Device with ceph, but didn't see any links to documentation steps that folks were following. Is the Managed Block Storage domain a supported feature in oVirt 4.4.2, and if so, where is the documentation for using it? --Mike [1]ovirt.org/documentation/administration_guide/

Moving VM disks from one storage domain to another. Automate?
by Green, Jacob Allen /C 09 Oct '20

09 Oct '20

I am looking for an automated way, via Ansible to move a VM disk from one storage domain to another. I found the following, https://docs.ansible.com/ansible/latest/modules/ovirt_disk_module.html and while it mentions copying a VM disk image from one domain to another it does not mention a live storage migration. Which is what I am looking to do. I want to take roughly 100 VMs and move their disk images from one domain to another that is available to the datacenter in some automated/scripted fashion. I am just curious if anyone out there has had to do this and how they tackled it. Or perhaps I am missing some easy obvious way, other than clicking all the disks and clicking move. However from the looks of it, if I did click all the disk and selected move, it appears RHV tries to do them all at once, which is probably not ideal, I would like it to move the disks in a serial One after another fashion, to conserve throughput and IO. I also did not see anything on Ansible galaxy or the ovirt github that would do this. Thank you.

oVirt Node 4.4.2 is now generally available
by Sandro Bonazzola 06 Oct '20

06 Oct '20

oVirt Node 4.4.2 is now generally available The oVirt project is pleased to announce the general availability of oVirt Node 4.4.2 , as of September 25th, 2020. This release completes the oVirt 4.4.2 release published on September 17th Important notes before you install / upgrade Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJ… ) How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.2 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.2 (redeploy in case of already being on 4.4.2). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>.

Is it possible to change scheduler optimization settings of cluster using ansible or some other automation way
by Kushagra Agarwal 03 Oct '20

03 Oct '20

I was hoping if i can get some help with the below oVirt scenario: *Problem Statement*:- Is it possible to change scheduler optimization settings of cluster using ansible or some other automation way *Description*:- Do we have any ansible module or any other CLI based approach which can help us to change 'scheduler optimization' settings of cluster in oVIrt. Scheduler optimization settings of cluster can be found under Scheduling Policy tab ( Compute -> Clusters(select the cluster) -> click on edit and then navigate to scheduling policy Any help in this will be highly appreciated. Thanks, Kushagra

VM AutoStart
by Jeremey Wise 01 Oct '20

01 Oct '20

When I have to shut down cluster... ups runs out etc.. I need a sequence set of just a small number of VMs to "autostart" Normally I just use DNS FQND to connect to oVirt engine but as two of my VMs are a DNS HA cluster.. as well as NTP / SMTP /DHCP etc... I need those two infrastructure VMs to be auto boot. I looked at HA settings for those VMs but it seems to be watching for pause /resume.. but it does not imply or state auto start on clean first boot. Options? -- p <jeremey.wise(a)gmail.com>enguinpages

I just noticed when HCI setup bult the gluster engine / data / vmstore volumes... it did use correctly the definition of 10Gb "back end" interfaces / hosts.

Is there any way to convert V4 to V5 (there are running VMs on them) to be able upgrade to 4.4? --

Replica Question
by C Williams 30 Sep '20

30 Sep '20

Hello, We recently received 5 servers. All have about 3 TB of storage. I want to deploy an oVirt HCI using as much of my storage and compute resources as possible. Would oVirt support a "replica 5" HCI (Compute/Gluster) cluster ? I have deployed replica 3s and know about replica 2 + arbiter -- but an arbiter would not be applicable here -- since I have equal storage on all of the planned bricks. Thank You For Your Help !!

Is it possible to change scheduler optimization settings of cluster using ansible or some other automation way
by kushagra2agarwal＠gmail.com 30 Sep '20

30 Sep '20

Do we have any ansible module or any other CLI based approach which can help us to change 'scheduler optimization' settings of cluster in oVIrt. Scheduler optimization settings of cluster can be found under Scheduling Policy tab ( Compute -> Clusters(select the cluster) -> click on edit and than navigate to scheduling policu option) Scheduler Optimization Optimize for Utilization Optimize for Speed

I have a VM which was send a "Reboot" and "Shutdown" command in short succession (two admins who were not thinking the same way) and now the VM is Stuck in "Rebooting". It has no Host assigned and when trying to turn it of (via Shutdown or Power Off) it gives this error: Sep 29, 2020, 10:27:10 AM Failed to power off VM <vm_name> (Host: <UNKNOWN>, User: admin@internal-authz).

oVirt Change hosts to FQDN
by Jeremey Wise 29 Sep '20

29 Sep '20

I posted that I had wiped out the oVirt-engine.. running cleanup on all three nodes. Done a re-deployment. Then to add nodes back.. though all have entries for eachother in /etc/hosts and ssh works fine via short and long name. I added nodes back into cluster.. but had to do it via IP to get past error. Now, if I go to create a volume via the GUI in gluster I get: Error while executing action Create Gluster Volume: Volume create failed: rc=30800 out=() err=["Host 172_16_100_102 is not in 'Peer in Cluster' state"] Which seems to be related to using IP vs DNS to add gluster volumes https://bugzilla.redhat.com/show_bug.cgi?id=1055928 Question: how do i fix the hosts in cluster being defined by IP vs desired hostname? -- jeremey.wise(a)gmail.com

Hello, having to monitor and check live storage migrations, it seems to me that scrolling through events I can see information about the target storage domain name, but nothing about the source. Is it correct? Can it be added? Which kind of rfe bugzilla should I use in case? Against what? Thanks, Gianluca

Trouble with restoring hosted engine from backup
by Siddharth Patil 29 Sep '20

29 Sep '20

Dear all, I'm trying to restore hosted-engine from backup, but it fails with the following error message: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "\"Cluster name cannot be 'Default'. This is a reserved name for the default DataCenter. Please choose\" \" another name for the cluster\""} My DataCenter is called Primary and Cluster is called Default. I have two hosts node01 and node02, with shared storage through NFS. I'm running the restore on node02. I can restore successfully if I change the Cluster name, but then I cannot move node02 to the default cluster, or move node01 to the new cluster, as I cannot shut down the VMs currently running on node01. Please help! Regards, Siddharth

Newbie question on network
by valerio.luccio＠nyu.edu 28 Sep '20

28 Sep '20

I apologize for asking what is probably a very basic question. I installed and created a self-hosted engine using cockpit on a server. I can reach the self-hosted engine from anywhere within my network. I then created a new VM selecting the default ovirtmgmt for the network. The VM does not seem to connect to the network via the bridge. I the used the console to manually configured the network card and I have connectivity between the VM, the engine and the server, but not beyond. What am I doing wrong ? Can someone point to a good documentation page on the subject ? Thanks in advance, Valerio

Cannot change Cluster Compatibility Version after 4.4 upgrade
by paolo＠airaldi.it 28 Sep '20

28 Sep '20

Hi all, we have an oVirt 4.3 with 3 Hosts and 20 VMs. 2 Hosts are Dell PowerEdge R610 with 2 Intel(R) Xeon(R) CPU E5540 processor each (Intel Nehalem IBRS SSBD), while the third is an HP ProLiant ML350p Gen8 with 2 Intel(R) Xeon(R) CPU E5-2620 v2 processor (Intel SandyBridge IBRS SSBD MDS) They all are in the same Cluster. Some of the 20 VMs are Windows (Win 10, Win 2012 and Win 2016) We have upgraded to 4.4.2.6-1.el8 following the instruction https://www.ovirt.org/documentation/upgrade_guide/#SHE_Upgrading_from_4-3. We had some minor issues that have been fixed and now we need to change Cluster Compatibility Version, but it fails complaining about Win10 and Win2016 VMs. In agent.log, for each of them I have: WARN [org.ovirt.engine.core.bll.UpdateVmCommand] (default task-122) [292f1983] Validation of action 'UpdateVm' failed for user admin@internal-authz. Reasons: VAR__ACTION__UPDATE,VAR__TYPE__VM,CPU_TYPE_UNSUPPORTED_FOR_THE_GUEST_OS,$uns upportedCpus opteron_g1, conroe, nehalem, penryn The same messages appear even if the VMs are powered off. We tried to change the Operating System in one VM configuration and if we put Win2012 the VM is no more in the error list when we edit the Cluster, but we're not sure the VMs will restart once Cluster compatibility will be to 4.4 How can we proceed?

Hi 1) trunk all the network including management, VM traffic subnets in both ports and tag the management network as native 2) configure the bonds with active/backup with management IP while installing the OS 3) proceed the hosted engine installation in the same management network 4) once hosted engine is up, add all hosts and create vm traffic network with VLAN tags

Re: Recreating ISO storage domain

Actually ISO domain is not necessary. You can moutn it via FUSE to a system and either use the python script ( It was mentioned several times in the mailing list) or the API/UI to upload your ISOs to a data storage domain. I think it is about time to get rid of the deprecated ISO domain.

Even if increasing timeouts would fix the connectivity I suspect the core issue would still remain ... in the best case scenario it could be postponed a bit. Am I correct assuming those 2 DC are located in 2 different physical locations? If so then I would closely check the network itself first (including hardware like routers/switches).

oVirt - Engine - VM Reconstitute
by Jeremey Wise 26 Sep '20

26 Sep '20

As expected... this is a learning curve. My three node cluster.. in an attempt to learn how to do admin work on it, debug it... I have now redeployed the engine and even added second one on a node in cluster. But..... I now realize that my "production vms" are gone. In the past, on a manual build with KVM + Gluster .. when I repaired a damaged cluster I would just then browse to the xml file and import. I think with oVirt, those days are gone. As the PostGres engine knows the links to the disk / thin provision volumes / network / VM definition files. ###### Question: 1) Can someone point me to the manual on how to re-constitute a VM and bring it back into oVirt where all "oVirt-engines" were redeployed. It is only three or four VMs I typically care about (HA cluster and OCP ignition/ Ansible tower VM). 2) How do I make sure these core VMs are able to be reconstituted. Can I create a dedicated volume where the VMs are full provisioned, and the path structure is "human understandable". 3) I know that you can backup the engine. If I had been a smart person, how does one backup and recover from this kind of situation. Does anyone have any guides or good articles on this? Thanks, -- p <jeremey.wise(a)gmail.com>enguinpages

oVirt host "unregistered"
by Jeremey Wise 25 Sep '20

25 Sep '20

Trying to get all the 3 node cluster back fully working... clearing out all the errors. I noted that the HCI wizard.. I thing SHOULD have deployed a hosted engine on the nodes, but this is not the case .. Only thor... the first node in cluster has hosted engine. I tried to redeploy this via the Cockpit wizard to add engine to host.. but I think this may not have been correct repair path. Now node in cluster shows all bricks... green (so it detects after reboot that host is back up and working.. but hosts lists it as "red triangle" with error "unregistered" I also just tried on third node to "edit" -> Host Engine -> and click drop box and choose "deploy" only log in event is "Host medusa configuration was updated by admin@internal-authz. 9/24/208:49:24 PM" but nothing changes.

Node 4.4.1 gluster bricks
by Staniforth, Paul 25 Sep '20

25 Sep '20

Hello, how do you manage a gluster host when upgrading a node? I upgraded/replaced 2 nodes with the new install and can't recreate any gluster bricks. 1 node I wiped it clean and the other I left the 3 gluster brick drives untouched. If I try to create bricks using the UI on the nodes, I get an internal server error. When I try to create a PV from the clean disk, I get device excluded by filter. e.g. pvcreate /dev/sdb Device /dev/sdb excluded by a filter. pvcreate /dev/mapper/SSDSC2KB240G7R_BTYS83100E0S240AGN Device /dev/mapper/SSDSC2KB240G7R_BTYS83100E0S240AGN excluded by a filter.

oVirt 4.4.2 is now generally available
by Lev Veyde 25 Sep '20

25 Sep '20

The oVirt project is excited to announce the general availability of oVirt 4.4.2 , as of September 17th, 2020. This release unleashes an altogether more powerful and flexible open source virtualization solution that encompasses hundreds of individual changes and a wide range of enhancements across the engine, storage, network, user interface, and analytics, as compared to oVirt 4.3. Important notes before you install / upgrade Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended). Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported. For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJ… ) Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. What’s new in oVirt 4.4.2 Release? This update is the second in a series of stabilization updates to the 4.4 series. This release is available now on x86_64 architecture for: - Red Hat Enterprise Linux 8.2 - CentOS Linux (or similar) 8.2 - CentOS Stream (tech preview) This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: - Red Hat Enterprise Linux 8.2 - CentOS Linux (or similar) 8.2 - CentOS Stream (tech preview) oVirt Node 4.4 based on CentOS Linux 8.2 (available for x86_64 only) will be released separately due to a blocker issue (Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864>). oVirt Node and Appliance have been updated, including: - oVirt 4.4.2: http://www.ovirt.org/release/4.4.2/ - Ansible 2.9.13: https://github.com/ansible/ansible/blob/stable-2.9/changelogs/CHANGELOG-v2.… - Glusterfs 7.7: https://docs.gluster.org/en/latest/release-notes/7.7/ See the release notes [1] for installation instructions and a list of new features and bugs fixed.

[ANN] oVirt 4.4.3 Second Release Candidate is now available for testing
by Lev Veyde 25 Sep '20

25 Sep '20

oVirt 4.4.3 Second Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.3 Second Release Candidate for testing, as of September 25th, 2020. This update is the third in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.3 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.3 (redeploy in case of already being on 4.4.3). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production.

export to ova

Hi to all. Hi try to ank another time the same question: in our tests ovirt seems to be able to make only one export to ova at time. also on different hosts and datacenter. Someone can explain to us why?? this is for us a big issue, because we use it in a backup script of more than 50 VMs and counting.... We also already opened a bug without any useful response: https://bugzilla.redhat.com/show_bug.cgi?id=1855782 Regards, -- -- Shellrent - Il primo hosting italiano Security First *Tommaso De Marchi* /COO - Chief Operating Officer/ Shellrent Srl Via dell'Edilizia, 19 - 36100 Vicenza Tel. 0444321155 <tel:+390444321155> | Fax 04441492177

oVirt 4.3 HCI ovirtmgmt vlan problem
by wodel youchi 25 Sep '20

25 Sep '20

Hi, I deployed an HCI of three nodes using ovirt 4.3 on a flat network at the beginning, now we need to use VLAN on the management network. I have ovirtmgmt over bond2, this bond will have three vlans : vlan 10 for management, vlan20 for DMZ and vlan30 for DMZ2. On the switch, I did configure the concerned ports to support ; the native vlan (untagged), the vlan10 (tagged), ...etc. Then I activated the tag on the ovirtmgmt network on the web UI, I did lose connexion to the hypervisors and things got weird, I then put my machine on vlan10, I saw that two of my hypervisors had their network configuration modified to use the vlan10, but not the hypervisor where the VM-engine was running. I created the vlan manually on that hypervisor, then I started the VM-Manager, all hosts were recognized. Then I stopped, then started the platforme again. Still the same problem, two hosts are correct with their vlan : bond2.10 created, but the third no vlan. Doing the configuration manually works, but it does not survive reboot, is there a way to force vdsm to accept the new configuration on that faulty host? Regards.

LVM-Thin error node instalation
by Jorge Visentini 24 Sep '20

24 Sep '20

Hello. I'm having trouble installing 4.4.2. The same problem happened in the 4.4.1 media. At the time of post installation, it gives error of LVM Thin Provisioning. I tried to switch from LVM Thin to LVM and the same error happened. In version 4.3 this error does not happen. I was unable to copy the error text, so I am attaching the images. [image: ovirt_installer01.jpg] [image: ovirt_installer02.jpg] Thank you all! -- Att, Jorge Visentini +55 55 98432-9868

ISO Repo
by Jeremey Wise 24 Sep '20

24 Sep '20

I saw notes about oVirt 4.4 may no longer support ISO images... but there are times like now I need to build based on specific ISO images. I tried to do a cycle to create an image file 8GB then do dd if=blah.iso of=/<random disk ID image file name> Created a new vm with this as boot disk and it fails to boot... so.. back to "create volume for iso images" But when I do that I get error New Domain -> "Domain function" =iso Storage type = glusterFs Use Managed Gluster volume -> Select already working gluster file space "thor.penguinpages.local:/iso VFS Type: glusterfs mount options: backup-volfile-servers=odin.penguinpages.local:medusa.penguinpages.local Error: Error while executing action: Cannot add Storage Connection. Performance o_direct option is not enabled for storage domain. Questions: 1) Why did the image and dd of iso to boot disk not work? 2) Any ideas about create of iso mount volume? -- penguinpages

Gluster Name too long
by Jeremey Wise 24 Sep '20

24 Sep '20

Deployment on three node cluster using oVirt HCI wizard. I think this is a bug where it needs to do either a pre-flight name length validation, or increase valid field length. I avoid using /dev/sd# as those can change. And the wizard allows for this change to a more explicit devices Ex: /dev/mapper/Samsung_SSD_850_PRO_512GB_S250NXAGA15787L Error: TASK [gluster.infra/roles/backend_setup : Create a LV thinpool for similar device types] *** task path: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/thin_pool_create.yml:239 failed: [thorst.penguinpages.local] (item={'vgname': 'gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L', 'thinpoolname': 'gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L', 'poolmetadatasize': '3G'}) => {"ansible_loop_var": "item", "changed": false, "err": " Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" is too long.\n Full LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tmeta\" is too long.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tmeta\" length 130 is not supported.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" length 130 is not supported.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tmeta\" length 130 is not supported.\n Internal error: LV name \"gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L/gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L_tdata\" length 130 is not supported.\n", "item": {"poolmetadatasize": "3G", "thinpoolname": "gluster_thinpool_gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L", "vgname": "gluster_vg_Samsung_SSD_850_PRO_512GB_S250NXAGA15787L"}, "msg": "Creating logical volume 'None' failed", "rc": 5} failed: [medusast.penguinpages.local] (item={'vgname': 'gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306', 'thinpoolname': 'gluster_thinpool_gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306', 'poolmetadatasize': '3G'}) => {"ansible_loop_var": "item", "changed": false, "err": " Internal error: LV name \"gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306/gluster_thinpool_gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306\" length 130 is not supported.\n", "item": {"poolmetadatasize": "3G", "thinpoolname": "gluster_thinpool_gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306", "vgname": "gluster_vg_SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306"}, "msg": "Creating logical volume 'None' failed", "rc": 5} changed: [odinst.penguinpages.local] => (item={'vgname': 'gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137', 'thinpoolname': 'gluster_thinpool_gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137', 'poolmetadatasize': '3G'}) => {"ansible_loop_var": "item", "changed": true, "item": {"poolmetadatasize": "3G", "thinpoolname": "gluster_thinpool_gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137", "vgname": "gluster_vg_Micron_1100_MTFDDAV512TBN_17401F699137"}, "msg": ""} I will revert back to /dev/sd# for now... but this should be cleaned up.

Host has to be reinstalled
by Jeremey Wise 23 Sep '20

23 Sep '20

Trying to repair / clean up HCI deployment so it is HA and ready for "production". I have gluster now showing three bricks all green Now I just have error on node.. and of course the node which is hosting the ovirt-engine # (as I can not send images to this forum... I will move to a breadcrumb posting) Compute -> Hosts -> "thor" (red exclamation) "Host has to be reinstalled" To fix gluster... i had to reinstall "vdsm-gluster" But what package does this error need to be reviewed / fixed with? -- penguinpages

CLI for HCI setup
by Michael Thomas 23 Sep '20

23 Sep '20

Is there a CLI for setting up a hyperconverged environment with glusterfs? The docs that I've found detail how to do it using the cockpit interface[1], but I'd prefer to use a cli similar to 'hosted-engine --deploy' if it is available. Thanks, --Mike [1]https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying…

info on iSCSI connection setup in oVirt 4.4
by Gianluca Cecchi 23 Sep '20

23 Sep '20

Hello, supposing to have a node that connects to an iSCSI storage domain in oVirt 4.4, is there any particular requirement in the configuration of the network adapter (ifcfg-eno1 file) when I pre-configure the server OS? Eg, do I need to have it managed by NetworkManager in 4.4? Can I instead set NM_CONTROLLED=no for this controller? Thanks in advance, Gianluca

Question on "Memory" column/field in Virtual Machines list/table in ovirt GUI
by KISHOR K 23 Sep '20

23 Sep '20

Hi, Memory field/column for few of VMs in our ovirt (Compute -> Virtual Machines -> Memory column) shows more than 90%. But, when I checked (from free and also other commands) the actual "used" memory by those VMs, it is less than 60%. What I see (from free -h) is that ovirt seems to be considering both "used" + "buff/cache" memory and is reporting the same in GUI. Isn't it the "available" memory that should be considered, because that is the actual memory available and cache memory is something that is adjusted every time? :~> free -h total used free shared buff/cache available Mem: 15Gi 6.8Gi 724Mi 310Mi 8.1Gi 9.2Gi Swap: 0B 0B 0B Can someone help to answer. Thanks ! /Kishore

console breaks with signed SSL certs
by Philip Brown 23 Sep '20

23 Sep '20

Chrome didnt want to talk AT ALL to ovirt with self-signed certs (Because HSTS is enabled) So I installed signed wildcard certs to the engine, and the nodes, following http://187.1.81.65/ovirt-engine/docs/manual/en-US/html/Administration_Guide… and https://cockpit-project.org/guide/172/https.html and chrome is happy now... except that suddenly, consoles refuse to work. and there are no useful errors that I see, other than "Unable to connect to the graphic server" from the remote viewer app. I see someone not too long ago had the exact same problem, in https://www.mail-archive.com/users@ovirt.org/msg58814.html but.. no answer was given to him?

oVirt - KVM QCow2 Import
by Jeremey Wise 22 Sep '20

22 Sep '20

I rebuilt my lab environment. And their are four or five VMs that really would help if I did not have to rebuild. oVirt as I am now finding when it creates infrastructure, sets it out such that I cannot just use older means of placing .qcow2 files in folders and .xml files in other folders.... and they show up on services restarting. How do I import VMs from files? I found this article but implies VM is running: https://www.ovirt.org/develop/release-management/features/virt/KvmToOvirt.h… https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/ht… I need a way to import a file. Even if it means temporarily hosting on "KVM on one of the hosts to then bring in once it is up. Thanks -- penguinpages

I would not be wrong but it is not possible to switch from Centos7 to Centos8 .....Can anyone give me some advice?Thank you all!!!

VM stuck in "reboot in progress" ("virtual machine XXX should be running in a host but it isn't.").
by Gilboa Davara 22 Sep '20

22 Sep '20

Hello all (and happy new year), (Note: Also reported as https://bugzilla.redhat.com/show_bug.cgi?id=1880251) Self hosted engine, single node, NFS. Attempted to install CentOS over an existing Fedora VM with one host device (USB printer). Reboot failed, trying to boot from a non-existent CDROM. Tried shutting the VM down, failed. Tried powering off the VM, failed. Dropped cluster to global maintenance, reboot host + engine (was planning to upgrade it anyhow...), VM still stuck. When trying to power off the VM, the following message can be found the in engine.log: 2020-09-18 07:58:51,439+03 INFO [org.ovirt.engine.core.bll.StopVmCommand] (EE-ManagedThreadFactory-engine-Thread-42) [7bc4ac71-f0b2-4af7-b081-100dc99b6123] Running command: StopVmCommand internal: false.

My question is simple: Pending a solution to the bug, can I somehow drop the state of the VM? It's currently holding a sizable disk image and a USB device I need (printer). As it's my private VM cluster, I have no problem dropping the site completely for maintenance. Thanks, Gilboa

Cannot import VM disks from previously detached storage domain
by Strahil Nikolov 22 Sep '20

22 Sep '20

Hello All, I would like to ask how to proceed further. Here is what I have done so far on my ovirt 4.3.10: 1. Set in maintenance and detached my Gluster-based storage domain 2. Did some maintenance on the gluster 3. Reattached and activated my Gluster-based storage domain 4. I have imported my ISOs via the Disk Import tab in UI Next I tried to import the VM Disks , but they are unavailable in the disk tab So I tried to import the VM: 1. First try - import with partial -> failed due to MAC conflict 2. Second try - import with partial , allow MAC reassignment -> failed as VM id exists -> recommends to remove the original VM 3. I tried to detach the VMs disks , so I can delete it - but this is not possible as the Vm already got a snapshot. What is the proper way to import my non-OS disks (data domain is slower but has more space which is more suitable for "data") ? Best Regards, Strahil Nikolov

Hi Everyone, In a test environment I'm trying to deploy a single node self hosted engine 4.4 on CentOS 8 from a 4.3 backup. The actual setup is: - node1 with CentOS7, oVirt 4.3 with a working SH engine. The data domain is a local NFS; - node2 with CentOS8, where we are triyng to deploy the engine starting from the node1 engine backup - host1, with CentOS78, running a couple of VMs (4.3) I'm following the guide: https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_the_Manager_to… Everything seems working fine, the engine on the node1 is in maintenance:global mode and the ovirt-engine service i stopped.

About the VM it’s configured with 10 CPUs, 48GB of RAM running oVirt 4.3.10 with iSCSI storage to a FreeNAS box, where the VM disks are running; there are a 300GB disc for C:\ and 2TB disk for D:\. Any ideia on how to start troubleshooting it? Thanks,

in ovirt-engine all host show the status at "non-responsive"
by momokch＠yahoo.com.hk 22 Sep '20

22 Sep '20

hello everyone, I apologize for asking what is probably a very basic question. i have 4 hosts running on the ovirt-engine, but on the last week the alert show all the hosts status has gone to non responsive like the following statement Host 1 became non responsive. It has no power management configured. Please check the host status, manually reboot it, and click "Confirm Host Has Been Rebooted" all the storage, vm, cannot detect on the ovirt-engine, does anyone face this before? and also the alert also show ""Engine's certification has expired at 2020-08-18. Please renew the engine's certification"" is it related to the hosts become non-responsive??? i have already regenerate the ovirt-engine cert from the previous post: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/ZI5WNU6OB6FZMQ… Yours Sincerely, school it

Upgrading self-Hosted engine from 4.3 to oVirt 4.4
by Adam Xu 22 Sep '20

22 Sep '20

Hi ovirt I just try to upgrade a self-Hosted engine from 4.3.10 to 4.4.1.4. I followed the step in the document: https://www.ovirt.org/documentation/upgrade_guide/#SHE_Upgrading_from_4-3 the old 4.3 env has a FC storage as engine storage domain and I have created a new FC storage vv for the new storage domain to be used in the next steps. I backup the old 4.3 env and prepare a total new host to restore the env. in charter 4.4 step 8, it said: "During the deployment you need to provide a new storage domain. The deployment script renames the 4.3 storage domain and retains its data." it does rename the old storage domain. but it didn't let me choose a new storage domain during the deployment. So the new enigne just deployed in the new host's local storage and can not move to the FC storage domain. Can anyone tell me what the problem is? Thanks -- Adam Xu

routing policy problem in ovirt 4.4
by g.vasilopoulos＠uoc.gr 19 Sep '20

19 Sep '20

Hello I created a cluster of ovirt 4.4 with 5 servers, I have a diferent gateway, ovirtmgmt and display network. In 4.4 routing is managed from network manager. Network manager seems to "forget" and recreate the route each time. So I cannot connect to the virtual machines console unless I run a ping for about a minute on the display network ip of the hypervisor, so network manager "wakes up" and "recreates" the route. I use this work around but it is not something that a user can do. What is the proper way to do this ? Thank you

New oVirt Install - Host Engine Deployment Fails
by mblanton＠vnet.net 18 Sep '20

18 Sep '20

I am attempting a new oVirt install. I have two nodes installed (with oVirt Node 4.4). I have NFS shared storage for the hosted engine. Both nodes are Dell quad core Xeon CPUs with 32GB of RAM. Both have been hypervisors before, XCP-NG and Proxmox. However I'm very interested to learn oVirt now. The hosted engine deployment (through cockpit) fails during the "Finish" stage. I do see the initial files created on the NFS storage. [ INFO ] TASK [ovirt.hosted_engine_setup : Convert CPU model name] [ ERROR ] fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable.

But this is normal correct? The Cluster CPU type is "undefined" until the first host is added to the cluster. The error makes it seems that server_cpu_dict and not cluster_cpu.type is the problem. I'm not sure this is really the problem, but that is the only undefined variable I can find. Any advice or recommendation is appreciated -Thanks in advance

Re: Random hosts disconnects
by Artur Socha 18 Sep '20

18 Sep '20

Hi Anton, I am not sure if changing this value would fix the issue. Defaults are pretty high. For example vdsHeartbeatInSeconds=30seconds, vdsTimeout=180seconds, vdsConnectionTimeout=20seconds. Do you still have relevant logs from the affected hosts: * /var/logs/vdsm/vdsm.log* * /var/logs/vdsm/supervdsm.log* Please look for any jsonrpc errors ie. write/read errors or (connection) timeouts. Storage related warnings/errors might also be relevant. Plus system logs if possible: *journalctl -f /usr/share/vdsm/vdsmd* *journalctl -f /usr/sbin/libvirtd* In order to get system logs from particular time period please combine it with the following example using -S -U options: *journalctl -S "2020-01-12 07:00:00" -U "2020-01-12 07:15:00" * I haven't a clue what to look there for besides any warnings/errors or anything else that seems .... unusual.

Bad volume specification

18 Sep '20

Hi all, I'm having some issues with one VM. The VM won't start and it's showing problems with the virtual disks so I started the VM without any disks and trying to hot adding the disk and that's fail too. The servers are connected thru FC, all the other VMs are working fine. Any ideas?. Thanks!!

Low Performance (KVM Vs VMware Hypervisor) When running multi-process application
by Rav Ya 17 Sep '20

17 Sep '20

Hello Everyone, Please advice. Any help will be highly appreciated. Thank you in advance. Test Setup: 1. oVirt Centos 7.8 Virtulization Host 2. Guest VM Centos 7.8 (Mutiqueue enabled 6 vCPUs with 6 Rx Tx Queues) 3. The vCPUs are configured for host pass through (Pinned CPU). The Guest VM runs the application in userspace. The Application consists of the parent process that reads packets in raw socket mode from the interface and forwards then to child processes (~vCPUs) via IPC (shared memory – pipes). *The performance (throughput / CPU utilization) that I get with KVM is half of what I get with VMware.* Any thoughts on the below observations? Any suggestions? - KVM Guest VMs degraded performance when running multi-process applications. - High FUTEX time (Seen on the Guest VM when passing traffic). - *High SY: *System CPU time spent in kernel space (Seen on both Hypervisor and the Guest VMs only when running my application.) -Rav Ya

UPN suffix and my SAM account do not have the sames domains
by dominique.deschenes＠gcgenicom.com 17 Sep '20

17 Sep '20

I have a SSO authentication question. In my Active Directory, my UPN suffix login and my SAM account do not have the sames domains. Example : UPN : dominique.test(a)abc.com Sam account : domtest(a)local.lan On the VM portal, I am able to connect with dominique.test(a)abc.com but not with domtest(a)local.lan (I have the following message:server_error: Cannot resolve principal 'domtest(a)local.lan' If I connect to the VM PORTAL with dominique.test(a)abc.com, when I click on "RDP Console" to get the link, the login of the RDP is dominique.test(a)local.lan. So I have to manually change the login to dominique.test(a)abc.com. Is it possible to use the Sam account domtes(a)local.lan instead of the UPN ? if not, is it possible to adjust the consol.rdp configuration and include the domain abc.com instead of local.lan ? In research I found this, but I don't have access.

Re: Random hosts disconnects
by Anton Louw 17 Sep '20

Hi Everybody, Did some digging around, and saw a few things regarding “vdsHeartbeatInSeconds” I had a look at the properties file located at /etc/ovirt-engine/engine-config/engine-config.properties, and do not see an entry for “vdsHeartbeatInSeconds.type=Integer”. Seeing as these data centers are geographically split, could the “vdsHeartbeatInSeconds” potentially be the issue? Is it safe to increase this value after I add “vdsHeartbeatInSeconds.type=Integer” into my engine-config.properties file?

Ovirt legacy migration policy is missing
by ovirtand-cnj342＠yahoo.com 16 Sep '20

16 Sep '20

Hello, We have many cases of failed migrations, and reducing the load on the respective VMs made migration possible. Using "Suspend workload when needed" did not help either with the migrations, which only worked when stopping services on the VMs, thus reducing load. I was therefore trying to tweak the migration downtime setting. The suggested way of doing this is by using the Legacy migration policy. That being said, I am unable to find the Legacy migration policy in the VM Host tab, nor in the cluster's "Migration policy" tab. I cannot find any mention of it being left out of our current version (4.3.6.1) - moreover, the setting "Use custom migration downtime" (only available when using the Legacy migration policy) does exist in the interface - but I cannot find the Legacy policy itself. The only policies present are Minimal downtime (default for cluster), Post-copy migration and Suspend workload when needed. Is there a way to make the Legacy migration policy available if it's missing? Thanks! Best regards, Andy PS. Setting DefaultMaximumMigrationDowntime=20000 as default did not have any effect, presumably because the system uses one of the 3 pre-defined policies and ignores the "default"

Hello, I set cpu QoS as 10 and applied it to VM on oVirt 4.2, but it doesn't seem to work. compared to VM without QoS, there wasn't any difference in cpu usage. Also, there wasn't any <period>...</period> or <quota>...</quota> field related to QoS in libvirt file. is it right result?? Thanks,

Removal of deprecated init-scripts (network-scripts)
by Ales Musil 16 Sep '20

16 Sep '20

Hello, network-scripts for host networking were deprecated since oVirt 4.4. It will be removed completely in the 4.4.3 release. There is no action required for setups that did not change the configuration to use network-scripts backend (net_nmstate_enabled = false). Users that did disable nmstate should redeploy all affected hosts before 4.4.3. Also can you please tell us what was the reason to use network-scripts, if that is the case? Thank you. Best regards, Ales Musil -- Ales Musil Software Engineer - RHV Network Red Hat EMEA <https://www.redhat.com> amusil(a)redhat.com IM: amusil <https://red.ht/sig>

Random hosts disconnects
by Anton Louw 16 Sep '20

16 Sep '20

Hi All, I have a strange issue in my oVirt environment. I currently have a standalone manager which is running in VMware. In my oVirt environment, I have two Data Centers. The manager is currently sitting on the same subnet as DC1. Randomly, hosts in DC2 will say "Not Responding" and then 2 seconds later, the hosts will activate again. The strange thing is, when the manager was sitting on the same subnet as DC2, hosts in DC1 will randomly say "Not Responding" I have tried going through the logs, but I cannot see anything out of the ordinary regarding why the hosts would drop connection. I have attached the engine.log for anybody that would like to do a spot check. Thanks Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

Enable a cluster node to run the hosted engine
by rap＠isogmbh.de 16 Sep '20

16 Sep '20

Hi there, currently my team is evaluating oVirt and we're also testing several fail scenarios, backup and so on. One scenario was: - hyperconverged oVirt cluster with 3 nodes - self-hosted engine - simulate the break down of one of the nodes by power off - to replace it make a clean install of a new node and reintegrate it in the cluster Actually everything worked out fine. The new installed node and related bricks (vmstore, data, engine) were added to the existing Gluster storage and it was added to the oVirt cluster (as host). But there's one remaining problem: The new host doesn't have the grey crown, which means it's unable to run the hosted engine. How can I achieve that? I also found out that the ovirt-ha-agent and ovirt-ha-broker isn't started/enabled on that node. Reason is that the /etc/ovirt-hosted-engine/hosted-engine.conf doesn't exist. I guess this is not only a problem concerning the hosted engine, but also for HA VM's. Thank you for any advice and greetings, Marcus

It seems that the installation is all done, but I have a problem. it takes very long to open the web pages, plus it disconnect all the time. it is impossible to do anything. I can ping the hostname as I set up a sub-domain for it. to be honest, I am new to this and it took me days to get to this point. I think there are some issues with my network settings. if there are any oVirt experts that can check my installation and give me advice about how to improve it, it will be greatly appreciated.

Gluster quorum issue on 3-node HCI with extra 5-nodes as compute and storage nodes
by thomas＠hoberg.net 15 Sep '20

15 Sep '20

Yes, I've also posted this on the Gluster Slack. But I am using Gluster mostly because it's part of oVirt HCI, so don't just send me away, please! Problem: GlusterD refusing to start due to quorum issues for volumes where it isn’t contributing any brick (I've had this before on a different farm, but there it was transitory. Now I have it in a more observable manner, that's why I open a new topic) In a test farm with recycled servers, I started running Gluster via oVirt 3node-HCI, because I got 3 machines originally. They were set up as group A in a 2:1 (replica:arbiter) oVirt HCI setup with 'engine', 'vmstore' and 'data' volumes, one brick on each node. I then got another five machines with hardware specs that were rather different to group A, so I set those up as group B to mostly act as compute nodes, but also to provide extra storage, mostly to be used externally as GlusterFS shares. It took a bit of fiddling with Ansible but I got these 5 nodes to serve two more Gluster volumes 'tape' and 'scratch' using dispersed bricks (4 disperse:1 redundancy), RAID5 in my mind. The two groups are in one Gluster, not because they serve bricks to the same volumes, but because oVirt doesn't like nodes to be in different Glusters (or actually, to already be in a Gluster when you add them as host node). But the two groups provide bricks to distinct volumes, there is no overlap. After setup things have been running fine for weeks, but now I needed to restart a machine from group B, which has ‘tape’ and ‘scratch’ bricks, but none from original oVirt ‘engine’, ‘vmstore’ and ‘data’ in group A. Yet the gluster daemon refuses to start, citing a loss of quorum for these three volumes, even if it has no bricks in them… which makes no sense to me. I am afraid the source of the issue is concept issues: I clearly don't really understand some design assumptions of Gluster. And I'm afraid the design assumptions of Gluster and of oVirt (even with HCI), are not as related as one might assume from the marketing materials on the oVirt home-page. But most of all I'd like to know: How do I fix this now? I can't heal 'tape' and 'scratch', which are growing ever more apart while the glusterd on this machine in group B refuses to come online for lack of a quorum on volumes where it is not contributing bricks.

What is the purpose of memory deflation in oVirt memory ballooning?
by pub.virtualization＠gmail.com 15 Sep '20

15 Sep '20

Hi, guys Why does momd(ballooning manager in oVirt) explicitly deflate the balloon when host gets plenty of memory? as far as I know, momd is supporting memory ballooning with setMemory API to inflate/deflate the balloon in guest and I've just checked the memory change in the guest after inflating the balloon. as expected, memory(total, free, available) in the guest was reduced just after inflating the balloon, but it was "automatically" restored to its initial memory after a few seconds. So, here I'm wondering why deflation is additionally required even though it can be restored automatically just after seconds. Thanks.

oVirt disk disappeared after importing iSCSI domain
by gantonjo-ovirt＠yahoo.com 15 Sep '20

15 Sep '20

Hi all oVirt experts. So, I managed to f.. up a VM today. I had one VM running on a oVirt 4.3 cluster, where the disk was located on an iSCSI data domain. I stopped the VM, put the storage domain in maintenance mode, detached adn removed the storage domain from the ovirt 4.3 cluster. Then I imported the storage domain to our new oVirt 4.4.1 cluster, let the process convert it from V4 to V5 format and activated the storage domain in the new cluster. Entering the information page for the imported storage domain, I expected to see "Import VM" and "Import Disk" menus, but these menues did not appear as they did for other storage domains that I successfully had moved from old to new cluster. Clicking "Scan Disks" did not help either. So, now I am stuck with a storage domain where the VM's disk is located, but oVirt is not able to see the disk. What can I do to recover the lost disk from the storage domain? Any CLI commands available in ovirt 4.4.1 would be nice. Thanks in advance for your quick and good help.

Testing ovirt 4.4.1 Nested KVM on Skylake-client (core i5) does not work
by wodel youchi 14 Sep '20

14 Sep '20

Hi, I've been using my core i5 6500 (skylake-client) for some time now to test oVirt on my machine. However this is no longer the case. I am using Fedora 32 as my base system with nested-kvm enabled, when I try to install oVirt 4.4 as HCI single node, I get an error in the last phase which consists of copying the VM-Manager to the engine volume and boot it. It is the boot that causes the problem, I get an error about the CPU : *the CPU is incompatible with host CPU: Host CPU does not provide required features: mpx* *This is the CPU part from virsh domcapabilities on my physical machine* <cpu> <mode name='host-passthrough' supported='yes'/> <mode name='host-model' supported='yes'> *<model fallback='forbid'>Skylake-Client-IBRS</model> * <vendor>Intel</vendor> <feature policy='require' name='ss'/> <feature policy='require' name='vmx'/> <feature policy='require' name='pdcm'/> <feature policy='require' name='hypervisor'/> <feature policy='require' name='tsc_adjust'/> <feature policy='require' name='clflushopt'/> <feature policy='require' name='umip'/> <feature policy='require' name='md-clear'/> <feature policy='require' name='stibp'/> <feature policy='require' name='arch-capabilities'/> <feature policy='require' name='ssbd'/> <feature policy='require' name='xsaves'/> <feature policy='require' name='pdpe1gb'/> <feature policy='require' name='invtsc'/> <feature policy='require' name='ibpb'/> <feature policy='require' name='amd-ssbd'/> <feature policy='require' name='skip-l1dfl-vmentry'/> </mode> <mode name='custom' supported='yes'> <model usable='yes'>qemu64</model> <model usable='yes'>qemu32</model> <model usable='no'>phenom</model> <model usable='yes'>pentium3</model> <model usable='yes'>pentium2</model> <model usable='yes'>pentium</model> <model usable='yes'>n270</model> <model usable='yes'>kvm64</model> <model usable='yes'>kvm32</model> <model usable='yes'>coreduo</model> <model usable='yes'>core2duo</model> <model usable='no'>athlon</model> <model usable='yes'>Westmere-IBRS</model> <model usable='yes'>Westmere</model> <model usable='no'>Skylake-Server-IBRS</model> <model usable='no'>Skylake-Server</model> <model usable='yes'>Skylake-Client-IBRS</model> <model usable='yes'>Skylake-Client</model> <model usable='yes'>SandyBridge-IBRS</model> <model usable='yes'>SandyBridge</model> <model usable='yes'>Penryn</model> <model usable='no'>Opteron_G5</model> <model usable='no'>Opteron_G4</model> <model usable='no'>Opteron_G3</model> <model usable='yes'>Opteron_G2</model> <model usable='yes'>Opteron_G1</model> <model usable='yes'>Nehalem-IBRS</model> <model usable='yes'>Nehalem</model> <model usable='yes'>IvyBridge-IBRS</model> <model usable='yes'>IvyBridge</model> <model usable='no'>Icelake-Server</model> <model usable='no'>Icelake-Client</model> <model usable='yes'>Haswell-noTSX-IBRS</model> <model usable='yes'>Haswell-noTSX</model> <model usable='yes'>Haswell-IBRS</model> <model usable='yes'>Haswell</model> <model usable='no'>EPYC-IBPB</model> <model usable='no'>EPYC</model> <model usable='no'>Dhyana</model> <model usable='yes'>Conroe</model> <model usable='no'>Cascadelake-Server</model> <model usable='yes'>Broadwell-noTSX-IBRS</model> <model usable='yes'>Broadwell-noTSX</model> <model usable='yes'>Broadwell-IBRS</model> <model usable='yes'>Broadwell</model> <model usable='yes'>486</model> </mode> </cpu> *Here is the lscpu of my physical machine* # lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian Address sizes: 39 bits physical, 48 bits virtual CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per socket: 4 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 94 Model name: Intel(R) Core(TM) i5-6500 CPU @ 3.20GHz Stepping: 3 CPU MHz: 954.588 CPU max MHz: 3600.0000 CPU min MHz: 800.0000 BogoMIPS: 6399.96 Virtualization: VT-x L1d cache: 128 KiB L1i cache: 128 KiB L2 cache: 1 MiB L3 cache: 6 MiB NUMA node0 CPU(s): 0-3 Vulnerability Itlb multihit: KVM: Mitigation: Split huge pages Vulnerability L1tf: Mitigation;

oVirt HCI issue: GlusterD refusing to start due to quorum issues for volumes where it isn’t contributing any brick
by thomas＠hoberg.net 14 Sep '20

14 Sep '20

Sorry if it's a duplicate: I go an error on post... And yes I posted it on the Gluster slack first, but I am using Gluster only because the marketing on oVirt HCI worked so well... I got 3 recycled servers for an oVirt test environment first and set those up as 3-node HCI using defaults mostly, 2 replica + 1 arbiter, 'engine', 'vmstore' and 'data' volumes with single bricks for each node. I call these group A. Then I got another set of five machines, let's call them group B, with somewhat different hardware characteristics than group A, but nicely similar between themselves. I wanted to add these to the farm as compute nodes but also use their storage as general GlusterFS storage for a wider use. Group B machines were added as hosts and set up to run hosted-engine, but they do not contribute bricks to the normal oVirt volumes 'engine', 'vmstore' or 'data'. With some Ansible trickery I managed to set up two dispersed volumes (4 data: 1 redundancy) on group B 'scratch' and 'tape', mostly for external GlusterFS use. oVirt picked them up automagically, so I guess they could also be used with VMs. I expect to get more machines and adding them one-by-one to dispersed volumes with a fine balance between capacity and redundancy made me so enthusiastic about oVirt HCI in the first place... After some weeks of fine operation I had to restart a machine from group B for maintenance. When it came back up, GlusterD refuses to come online, because it doesn't have "quorum for volumes 'engine', 'vmstore' and 'data'".... It's a small surprise it doesn't *have* quorum, what's a bigger surprise is that it *asks* for quorum in a volume where it's not contributing any bricks. What's worse is that it then refuses to start serving its bricks for 'scratch' and 'tape', which are now growing apart without any chance of healing. How do I fix this? Is this a bug (my interpretation) or do I fundamentlly misunderstand how Gluster as a hyper scale out file system is supposed to work with potentially thousands of hosts contributing each dozens of bricks to each of hundreds of volumes in a single name space?

OVN Geneve tunnels not been established
by Konstantinos B 11 Sep '20

11 Sep '20

Hi all We have a small installation based on OVIRT 4.3. 1 Cluster is based on Centos 7 and the other on OVIRT NG Node image. The environment was stable till an upgrade took place a couple of months ago. As such we had to re-install one of the Centos 7 node and start from scratch. Even though the installation completed successfully and VMs are created, the following are not working as expected: 1. ovn geneve tunnels are not established with the other Centos 7 node in the cluster. 2. Centos 7 node is configured by ovirt engine however no geneve tunnel is established when "ovn-sbctl show" is issued on the engine. 3. no flows are shown on the engine on port 6642 for the ovs db. Does anyone have any experience on how to troubleshoot OVN on ovirt? Thank you

Failed to create a new VM in ovirt due to "The host did not satisfy internal filter Memory" error
by KISHOR K 10 Sep '20

10 Sep '20

Hi All, I'm new to Ovirt and not having a perfect experience with Ovirt yet. I ran into a strange issue today when I tried to create a new VM with 32GB in ovirt. VM creation basically due to an error, pasted below. Cannot run VM. There is no host that satisfies current scheduling constraints. See below for details:, The host host-01 did not satisfy internal filter Memory., The host host-01 did not satisfy internal filter Memory. After some troubleshooting, I found that there was enough available memory (around 120 GB free ) in the host to host new VM and there were around 10 VMs already running on this host. But, I noticed that ovirt is actually scheduling and creating VM based on "Max free Memory for scheduling new VMs" value, which seems to be set/updated based on total allocated memory for all VMs running on the host and it's not really the then consumed memory by running VMs. Can anyone help to explain if it is some kind of bug in ovirt or it expected behavior? If it is expected behavior, is there any possibility to change it to make sure VM is created based on actual free memory? Thanks a lot in advance for your support. /Kishore /Kishore

Diskless oVirt Nodes
by harryo.dk＠gmail.com 10 Sep '20

10 Sep '20

Hi, why does my ovirt hypervisor node crash when i pull the hypervisor boot drive? The following thread claims that the oVirt node hypervisor should lodad into memory, so boot disk failure shouldn't have any impact on a running node. https://lists.ovirt.org/pipermail/users/2014-December/029771.html Only memory failure should have a impact, and if RAM fails there is a possibility that the hypervisor OS would have crashed regardless. If you load the hypervisor OS into memory there will be moved/combined a point of failure (the boot disk) with another(the RAM). RAM=memory

Hyperconverged set up with Gluster and 6 Nodes
by Holger Petrick 09 Sep '20

09 Sep '20

Dear All, in all documentation to set up oVirt in a Hyperconverged system with Gluster says that it must have 3 Enterprise nodes. In our test environment we set up successfully with oVirt wizard an oVirt cluster with gluster + Arbiter and hosted engine. Is it also possible to build a cluster with 6 nodes? The wizard gives only the option to add 3 nodes. Is this kind of design supported? My idea is, first to set up the Gluster, then install the oVirt nodes and deploy the engine. Would this work? Any documentation avaiable? Thanks Holger

iSCSI multipath issue
by Nick Kas 08 Sep '20

08 Sep '20

Hello evryone, setup ovirt 4.4.1 on CentOS 8.2 as an experiment, and I am trying to get an iSCSI domain working but have issues. The little experimental cluster has 3 hosts. There is an ovirtmgmt network on the default vlan, and two iSCSI network (172.27.0/1.X) with vlans 20/21. ovirtmgmt has all the functions (Data, display, migration etc), and the iSCSI networks nothing yet, and they are not set as required. The SAN device is already serving a few iSCSI volumes to a vmware cluster, so I know things are fine on this end. It has two controllers, and four NICs per controller so a total of 8 NICs, half of the NICS per controller on 172.27.0.X and half on 172.27.1.X. When I create the iSCSI domain, I login to only one of the targets, and add the Volume, all is good and I can use the disc fine. However when I login to more than one of the targets, then I start having issues with the Volume. Even when I enabled multipath in the cluster, and I created a single multipath by selecting both of the 172.27.0/1.X networks, and all the targets, the end result was the same. The hosts have difficulty accessing the volume, they may even swing between 'non-operational' and 'up' if I transfer data to the volume. When I ssh to the hosts and i check things in the command line I also get inconsistent results between hosts, and blocks that appear with lsblk when I first setup iSCSI have dissapeared after I try to actively use the volume. I am new to iSCSI so I am not sure how to debug this. I am not sure if my multipath configuration is correct or not. The documentation on this part was not very detailed. I also tried to remove the domain, and try to experiment with mounting the iSCSI volume from the command line, but I cannot even discover the target from the command line, which is very bizarre. The command iscsiadm --mode discovery --target sendtargets --portal 172.27.0.55 --discover returns the message 'iscsiadm: cannot make connection to 172.27.0.55: No route to host'. Yet through ovirt, and if I select only one target, everything work fine! Any suggestions on how to start debugging this would really be appreciated.

Engine certificate and HTTPS : broken on recent Firefox
by Michaël Couren 08 Sep '20

08 Sep '20

Hi, Is there a "verified"* way to add a valid certificate to an oVirt 4.3 engine ? (or suppress HTTP Strict Transport Security) It is no more possible to add a security exception (on latest Firefox 80.0.1 Linux) and I don't want to use 2 browsers (like sanp-chromium just for oVirt...) *"verified" : I mean we have already tried official doc (many months ago) but with no success Thanks -- Cordialement / Best regards, Michaël Couren, ABES, Montpellier, France.

Hi Anton, Just to let you know. I investigated this issue. If you want to use keycloak in version >=10 you would need to define all additional scopes as 'optional client scopes' in your client configuration. In my case, on my test environment, I only had to add 'ovirt-ext=auth:sequence-priority=~' but in your case you may need all listed in error_description: *{"error_description":"Cannot authenticate user Invalid scopes: ovirt-app-api ovirt-ext=revoke:revoke-all ovirt-ext=token-info:authz-search ovirt-ext=token-info:public-authz-search ovirt-ext=token-info:validate ovirt-ext=token:password-access.","error":"access_denied"}* This configuration change is required because it has been changed/fixed how 'unknown' scopes are handled in keycloak. Now keycloak must always be aware of all scopes and previously unknown ones were simply ignored. Here is BZ with details: https://bugzilla.redhat.com/show_bug.cgi?id=1849569 best, Artur On Tue, Jun 23, 2020 at 5:03 PM Artur Socha <asocha(a)redhat.com> wrote: > On Tue, 2020-06-23 at 14:41 +0000, Anton Louw wrote: > > > > Hi Artur, > > > > Apologies for the late response.

Storage Domain won't activate
by Gillingham, Eric J (US 393D) 05 Sep '20

05 Sep '20

I recently removed a host from my cluster to upgrade it to 4.4, after I removed the host from the datacenter VMs started to pause on the second system they all migrated to. Investigating via the engine showed the storage domain was showing as "unknown", when I try to activate it via the engine it cycles to locked then to unknown again. /var/log/sanlock.log contains a repeating: add_lockspace e1270474-108c-4cae-83d6-51698cffebbf:1:/dev/e1270474-108c-4cae-83d6-51698cffebbf/ids:0 conflicts with name of list1 s1 e1270474-108c-4cae-83d6-51698cffebbf:3:/dev/e1270474-108c-4cae-83d6-51698cffebbf/ids:0 vdsm.log contains these (maybe related) snippets: --- 2020-09-03 20:19:53,483+0000 INFO (jsonrpc/6) [vdsm.api] FINISH getAllTasksStatuses error=Secured object is not in safe state from=::ffff:137.79.52.43,36326, flow_id=18031a91, task_id=8e92f059-743a-48c8-aa9d-e7c4c836337b (api:52) 2020-09-03 20:19:53,483+0000 ERROR (jsonrpc/6) [storage.TaskManager.Task] (Task='8e92f059-743a-48c8-aa9d-e7c4c836337b') Unexpected error (task:875) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 882, in _run return fn(*args, **kargs) File "<string>", line 2, in getAllTasksStatuses File "/usr/lib/python2.7/site-packages/vdsm/common/api.py", line 50, in method ret = func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/hsm.py", line 2201, in getAllTasksStatuses allTasksStatus = self._pool.getAllTasksStatuses() File "/usr/lib/python2.7/site-packages/vdsm/storage/securable.py", line 77, in wrapper raise SecureError("Secured object is not in safe state") SecureError: Secured object is not in safe state 2020-09-03 20:19:53,483+0000 INFO (jsonrpc/6) [storage.TaskManager.Task] (Task='8e92f059-743a-48c8-aa9d-e7c4c836337b') aborting: Task is aborted: u'Secured object is not in safe state' - code 100 (task:1181) 2020-09-03 20:19:53,483+0000 ERROR (jsonrpc/6) [storage.Dispatcher] FINISH getAllTasksStatuses error=Secured object is not in safe state (dispatcher:87) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/dispatcher.py", line 74, in wrapper result = ctask.prepare(func, *args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 108, in wrapper return m(self, *a, **kw) File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 1189, in prepare raise self.error SecureError: Secured object is not in safe state --- 2020-09-03 20:44:23,252+0000 INFO (tasks/2) [storage.ThreadPool.WorkerThread] START task 76415a77-9d29-4b72-ade1-53207cfc503b (cmd=<bound method Task.commit of <vdsm.storage.task.Task instance at 0x7fe99c27dea8>>, args=None) (thre adPool:208) 2020-09-03 20:44:23,266+0000 INFO (tasks/2) [storage.SANLock] Acquiring host id for domain e1270474-108c-4cae-83d6-51698cffebbf (id=1, wait=True) (clusterlock:313) 2020-09-03 20:44:23,267+0000 ERROR (tasks/2) [storage.TaskManager.Task] (Task='76415a77-9d29-4b72-ade1-53207cfc503b') Unexpected error (task:875) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 882, in _run return fn(*args, **kargs) File "/usr/lib/python2.7/site-packages/vdsm/storage/task.py", line 336, in run return self.cmd(*self.argslist, **self.argsdict) File "/usr/lib/python2.7/site-packages/vdsm/storage/sp.py", line 317, in startSpm self.masterDomain.acquireHostId(self.id) File "/usr/lib/python2.7/site-packages/vdsm/storage/sd.py", line 957, in acquireHostId self._manifest.acquireHostId(hostId, wait) File "/usr/lib/python2.7/site-packages/vdsm/storage/sd.py", line 501, in acquireHostId self._domainLock.acquireHostId(hostId, wait) File "/usr/lib/python2.7/site-packages/vdsm/storage/clusterlock.py", line 344, in acquireHostId raise se.AcquireHostIdFailure(self._sdUUID, e) AcquireHostIdFailure: Cannot acquire host id: ('e1270474-108c-4cae-83d6-51698cffebbf', SanlockException(22, 'Sanlock lockspace add failure', 'Invalid argument')) --- Another symptom is in the hosts view of the engine SPM bounces between "Normal" and "Contending". When it's Normal if I select Management -> Select as SPM I get "Error while executing action: Cannot force select SPM. Unknown Data Center status." I've tried rebooting the one remaining host in the cluster no to avail, hosted-engine --reinitialize-lockspace also seems to not solve the issue. I'm kind of stumped as to what else to try, would appreciate any guidance on how to resolve this. Thank You

Hi All, Using OLVM and having an issue connecting to a noVNC console on a secondary host. Im getting the Failed to connect. We are using the standalone host as the deployment of the self hosted kept failing, something about the machine not being able to run virtualised machines even though it can. Added a second kvm host to the management engine. Can create new machines, disks etc. Just when trying to connect to the console using noVNC. Any help would be appreciated.

Upgrade 4.3 to 4.4 node to manager communication error
by Pierre pit 03 Sep '20

03 Sep '20

I have a communication problem between all the nodes and the manager following the upgrade from 4.3 to 4.4. I followed the procedure of update 4.3 to 4.4 everything worked correctly, according to the import export scripts as well as the installation setup on the new manager in 4.4, all is ok. Only after connection to the manager, all the nodes are in a down state, there is no more communication between the manager newly installed in 4.4 and the nodes still in production in 4.3. In the manager I have this message for all the nodes: ` VDSM virtdell8 command Get Host Capabilities failed: PKIX path validation failed: java.security.cert.CertPathValidatorException: Algorithm constraints check failed on signature algorithm: SHA256withRSA` And on the nodes: ` 2020-09-01 17:38:13,083+0200 ERROR (Reactor thread) [ProtocolDetector.SSLHandshakeDispatcher] ssl handshake: SSLError, address: ::ffff:XXX.XXX.XXX.XXX (sslutils:264) vdsm[4400]: ERROR ssl handshake: SSLError, address: ::ffff:XXX.XXX.XXX.XXX` After a search on the forums I found a similar error on version 4.2 only the solution of comment `ssl_excludes` in the `/etc/vdsm/vdsm.conf` file but does not apply to my problem. I unfortunately had to backtrack because it was no longer possible to control ovirt and use the manager for our production. the new machine with the manager in 4.4 is offline while a solution is found Do you know where should I look in order to solve this problem? thank you in advance Pierre

Re: [ovirt 4.2]The snapshot is deleted after restoring the snapshot
by Strahil Nikolov 03 Sep '20

If you have snapshots like A -> B -> C and you restore A , it is normal to loose B & C. After all when you restore A , B & C never happened. Otherwise , ovirt should clone the snapshots in separate images and that is not the requested, right ?

How to Backup a VM
by Stefan Wolf 03 Sep '20

03 Sep '20

Hello to all I try to backup a normal VM. But It seems that I don't really understand the concept. At first I found the possibility to backup with the api https://www.ovirt.org/documentation/administration_guide/#Setting_a_storage…. Create a snapshot of the VM, finding the ID of the snapshot and the configuration of the VM makes sense to me. But at this point, I would download the config an the snapshot and put it to my backup storage. And not create a new VM attach the disk and run a backup with backup programm. And for restoring do the sam way backwards. If i look at other project, there seems do be a way to download the snapshot and configfile, or am I wrong? Maybe someone can explain to me why I should use additional software to install in an additional machine. Or even better someone can explain to me how I don't have to use additional backup software. And to the same topic backup. There is in the documentation the possibility to set up a backup storage It is nearly the same, create a snapshot, or clone the machine and export it to backup storage > Export the new virtual machine to a backup domain. See Exporting a Virtual Machine to a Data Domain in the Virtual Machine Management Guide. Sadly there is just writen what to do, not how, the link points to 404 page. maybe someone can explain to me how to use backup storage thank you very much shb

Ovirt Host Crashed
by Darin Schmidt 02 Sep '20

02 Sep '20

I am running this as an all in one system for a test bed at home. The system crashed which lead me to have to reinstall the OS (CentOS 8) and I imported the data stores but I cannot find any way to import the VM's that were in the DATA store. I havent had a chance to backup/export the VMs. I havent been able to find anything in the documentation on how to import these VMs. Any suggestions or links to what Im looking for? I had to create a new DATA store as the option for importing a local data store wasnt an option, I assume its because the host was down. THen I imported the old data store.

Mellanox OFED with oVirt
by Vinícius Ferrão 02 Sep '20

02 Sep '20

Hello, Anyone had success using Mellanox OFED with oVirt? Already learned some things: 1. I can’t use oVirt Node. 2. Mellanox OFED cannot be installed with mlnx-ofed-all since it breaks dnf. We need to rely on the upstream RDMA implementation. 3. The way to go is running: dnf install mlnx-ofed-dpdk-upstream-libs But after the installation I ended up with broken dnf: [root@c4140 ~]# dnf update Updating Subscription Management repositories. Last metadata expiration check: 0:03:54 ago on Tue 01 Sep 2020 11:52:41 PM -03.

How can Gluster be a HCI default, when it's hardly ever working?
by thomas＠hoberg.net 02 Sep '20

02 Sep '20

I've just tried to verify what you said here. As a base line I started with the 1nHCI Gluster setup. From four VMs, two legacy, two Q35 on the single node Gluster, one survived the import, one failed silently with an empty disk, two failed somewhere in the middle of qemu-img trying to write the image to the Gluster storage. For each of those two, this always happened at the same block number, a unique one per machine, not in random places, as if qemu-img reading and writing the very same image could not agree. That's two types of error and a 75% failure rate I created another domain, basically using an NFS automount export from one of the HCI nodes (a 4.3 node serving as 4.4 storage) and imported the very same VMs (source all 4.3) transported via a re-attached export domain to 4.4. Three of the for imports worked fine, no error with qemu-img writing to NFS. All VMs had full disk images and launched, which verified that there is nothing wrong with the exports at least. But there was still one, that failed with the same qemu-img error. I then tried to move the disks from NFS to Gluster, which internally is also done via qemu-img, and I had those fail every time. Gluster or HCI seems a bit of a Russian roulette for migrations, and I am wondering how much it is better for normal operations. I'm still going to try moving via a backup domain (on NFS) and moving between that and Gluster, to see if it makes any difference. I really haven't done a lot of stress testing yet with oVirt, but this experience doesn't build confidence.

HP blade G7, with be2net.
by Remulo 01 Sep '20

01 Sep '20

Hello I have some blades with 10GE interface that have / need the Emulex be2net driver, however it is no longer available on Redhat8 / Centos8. Is there any way to install ovirt to work on these machines? Here are some links to problems with Redhat. Emulex NIC using be2net driver https://access.redhat.com/solutions/1229853 https://access.redhat.com/solutions/514353 I did a lot of research and couldn't get a functional driver for ovirt. Thank you. -- Atenciosamente, Rêmulo Ferreira.

How can you avoid breaking 4.3.11 legacy VMs imported in 4.4.1 during a migration?
by thomas＠hoberg.net 01 Sep '20

01 Sep '20

Testing the 4.3 to 4.4 migration... what I describe here is facts is mostly observations and conjecture, could be wrong, just makes writing easier... While 4.3 seems to maintain a default emulated machine type (pc-i440fx-rhel7.6.0 by default), it doesn't actually allow setting it in the cluster settings: Could be built-in, could be inherited from the default template... Most of my VMs were created with the default on 4.3. oVirt 4.4 presets that to pc-q35-rhel8.1.0 and that has implications: 1. Any VM imported from an export on a 4.3 farm, will get upgraded to Q35, which unfortunately breaks things, e.g. network adapters getting renamed as the first issue I stumbled on some Debian machines 2. If you try to compensate by lowering the cluster default from Q35 to pc-i44fx the hosted-engine will fail, because it was either built or came as Q35 and can no longer find critical devices: It evidently doesn't take/use the VM configuration data it had at the last shutdown, but seems to re-generate it according to some obscure logic, which fails here. I've tried creating a bit of backward compatibility by creating another template based on pc-i440fx, but at the time of the import, I cannot switch the template. If I try to downgrade the cluster, the hosted-engine will fail to start and I can't change the template of the hosted-engine to something Q35. Currently this leaves me in a position where I can't separate the move of VMs from 4.3 to 4.4 and the upgrade of the virtual hardware, which is a different mess for every OS in the mix of VMs. Recommendations, tips anyone? P.S. A hypervisor reconstructing the virtual hardware from anywhere but storage at every launch, is difficult to trust IMHO.

Hi, Not sure if this is relevant but in the ovirt doc in the 4.2 to 4.3 upgrade the repo rpm is specified with 4,4 rpm . Thanks Carl [image: image.png]
