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.

Deploy oVirt Engine fail behind proxy
by Matteo Bonardi 21 Mar '24

21 Mar '24

Hi, I am trying to deploy the ovirt engine following self-hosted engine installation procedure on documentation. Deployment servers are behind a proxy and I have set it in environment and in yum.conf before run deploy.

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

OVS switch type for hosted-engine

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.

I am experiencing the error message in the ovirt-hosted-engine-setup-ansible-create_target_vm log {2020-05-06 14:15:30,024-0500 ERROR ansible failed {'status': 'FAILED', 'ansible_type': 'task', 'ansible_task': u"Fail if Engine IP is different from engine's he_fqdn resolved IP", 'ansible_result': u'type: <type \'dict\'>\nstr: {\'msg\': u"Engine VM IP address is while the engine\'s he_fqdn ovirt1-engine.kelleykars.org resolves to 192.168.122.2.

Now this bug looks like it may play but I don't see the failed rediness check in the this log https://access.redhat.com/solutions/4462431 or is it because the vm fails or dies or ???

Snapshot and disk size allocation
by jorgevisentini＠gmail.com 28 Oct '21

28 Oct '21

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.

Dear oVirt, We are currently running oVirt 4.3 and upgrade/migration to 4.4 won’t be possible for few more months.

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!

Libgfapi considerations
by Jayme 01 Jul '21

01 Jul '21

Are there currently any known issues with using libgfapi in the latest stable version of ovirt in hci deployments? 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

Gluster volume slower then raid1 zpool speed
by Harry O 28 Jan '21

28 Jan '21

Hi, Can anyone help me with the performance on my 3 node gluster on zfs (it is setup with one arbiter) The performance on the single vm I have on it (with engine) is 50% worse then a single bare metal disk, on the writes. I have enabled "Optimize for virt store" I run 1Gbps 1500MTU network, could this be the write performance killer? Is this to be expected from a 2xHDD zfs raid one on each node, with 3xNode arbiter setup? Maybe I should move to raid 5 or 6? Maybe I should add SSD cache to raid1 zfs zpools? What are your thoughts? What to do for optimize this setup? I would like to run zfs with gluster and I can deal with a little performance loss, but not that much.

OVN and change of mgmt network
by Gianluca Cecchi 26 Jan '21

26 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 ....

ovirt 4.3 - locked image vm - unable to remove a failed deploy of a guest dom
by 3c.monitor＠gruppofilippetti.it 09 Dec '20

09 Dec '20

Hi all. I've deployed a VM from a corrupted template (it's disk is missing, but I've checked it later...). My Software Version is:4.3 Now, I have an unmanaged VM in inventory and unable to remove it too. It's reference is "locked image". I've restarted ovirt-engine many times on self-hosted engine and hosts too, but no benefits. So, what's now? I've also consulted: https://access.redhat.com/solutions/396753 but still no results. No tasks or items results to be "locked"... Any other ideas? Thanks a lot.

How to install win-virtio Drivers (aka guest tools) silently
by t.hofmann＠klett-it.net 09 Dec '20

09 Dec '20

Hi, i am currently trying to automate an upgrade process from the "old" oVirt 4.3 Guest Tools new one which should using starting with oVirt 4.4 To achieve this I have to install the win-virtio tools quietly. This works even if I use the parameters /install /passive /norestart. But then the oVirt Guest Agent is not installed. Is there a parameter or another way to install it during a silent installation? Thanks in advance. - Tim

Cannot SSH into the self hosted host (going through tutorial)
by jenia.ivlev＠gmail.com 03 Dec '20

03 Dec '20

Hello. I want to install oVirt on my PC and for this purpose I'm following the tutorial which instructed me to make a VM and install there the oVirt self hosted host: https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engin… I cannot SSH to this new oVirt install - I get the error "Connection refused" (Even though I see something listening on port 22 by running `netstat -an`). So I tried stopping `sshd`and I got the same error. Tried to do all of this with `telnet 192.168.122.1 22`, I get the same error "Connection refused". Also, Yum returns "could not resolve host: https://mirrors.fedoraproject.org" I can ping the machine though from my PC. I turned off `firewalld`. `iproute -S` returns `ACCEPT` for everything. My PC is running archlinux and I installed the new VM using "Virtual Machine Manager". Normally, I can easily SSH to any VM I create. Maybe someone know what I'm doing wrong? Thanks kindly Jenia P.S. Running `nodectl check` returns "ok" for all.

After that I have installed hosted engine from console with command - "hosted-engine --deploy" and than installed successfully. From console was able to retrieve iSCSI luns and select one there. Who can try to deploy ovirt from cockpit?

Guest OS Memory Free/Cached/Buffered: Not Configured
by Stefan Seifried 30 Nov '20

30 Nov '20

Hi, I'm quite new to oVirt, so my apologizies if I'm asking something dead obvious: I noticed that there is an item in the 'General Tab' of each VM, which says 'Guest OS Memory Free/Cached/Buffered' and on all my VM's it says 'Not Configured'. Right now I'm trying to figure out how to enable this feature. I assume that this gives me the equivalent output of executing 'free' on the shell on a Linux guest. Googling and digging around the VMM guide did not give me any pointers so far. Thanks in advance, Stefan PS: A little background info: I have one 'client' which keeps nagging me to increase the RAM on his VM because it's constantly operating at 95% memory load (as shown on the VM dashboard). After a quick investigation with 'free' I could see that Linux has built up the disk cache to 12G (from 16G total, no swapping occured). My intention is to make the real memory load visible to him, as he has already access to the VM portal for shutdown/restart/etc.

Re: Constantly XFS in memory corruption inside VMs

Are you using "nobarrier" mount options in the VM ? If yes, can you try to remove the "nobarrrier" option.

If there's any corruption it may be silent corruption... I've cases where the VM was new, just installed, run dnf -y update to get the updated packages, rebooted, and boom XFS corruption. So perhaps the motion process isn't the one to blame. But, in fact, I remember when moving a VM that it went down during the process and when I rebooted it was corrupted. But this may not seems related. It perhaps was already in a inconsistent state. Anyway, here's the mount options: Host1: 192.168.10.14:/mnt/pool0/ovirt/vm on /rhev/data-center/mnt/192.168.10.14:_mnt_pool0_ovirt_vm type nfs4 (rw,relatime,vers=4.1,rsize=131072,wsize=131072,namlen=255,soft,nosharecache,proto=tcp,timeo=100,retrans=3,sec=sys,clientaddr=192.168.10.1,local_lock=none,addr=192.168.10.14) Host2: 192.168.10.14:/mnt/pool0/ovirt/vm on /rhev/data-center/mnt/192.168.10.14:_mnt_pool0_ovirt_vm type nfs4 (rw,relatime,vers=4.1,rsize=131072,wsize=131072,namlen=255,soft,nosharecache,proto=tcp,timeo=100,retrans=3,sec=sys,clientaddr=192.168.10.1,local_lock=none,addr=192.168.10.14) The options are the default ones.

Ovirt 4.4.3 - Unable to start hosted engine
by Marco Marino 28 Nov '20

28 Nov '20

Hi, I have an ovirt 4.4.3 with 2 clusters, hosted engine and iscsi storage. First cluster, composed of 2 servers (host1 and host2), is dedicated to the hosted engine, the second cluster is for vms. Furthermore, there is a SAN with 3 luns: one for hosted engine storage, one for vms and one unused. My SAN is built on top of a pacemaker/drbd cluster with 2 nodes with a virtual ip used as iscsi Portal IP. Starting from today, after a failover of the iscsi cluster, I'm unable to start the hosted engine. It seems that there is some problem with storage. Actually I have only one node (host1) running in the cluster. It seems there is some lock on lvs, but I'm not sure of this. Here are some details about the problem: 1. iscsiadm -m session iSCSI Transport Class version 2.0-870 version 6.2.0.878-2 Target: iqn.2003-01.org.linux-iscsi.s1-node1.x8664:sn.2a734f67d5b1 (non-flash) Current Portal: 10.3.8.8:3260,1 Persistent Portal: 10.3.8.8:3260,1 ********** Interface: ********** Iface Name: default Iface Transport: tcp Iface Initiatorname: iqn.1994-05.com.redhat:4b668221d9a9 Iface IPaddress: 10.3.8.10 Iface HWaddress: default Iface Netdev: default SID: 1 iSCSI Connection State: LOGGED IN iSCSI Session State: LOGGED_IN Internal iscsid Session State: NO CHANGE ********* Timeouts: ********* Recovery Timeout: 5 Target Reset Timeout: 30 LUN Reset Timeout: 30 Abort Timeout: 15 ***** CHAP: ***** username: <empty> password: ******** username_in: <empty> password_in: ******** ************************ Negotiated iSCSI params: ************************ HeaderDigest: None DataDigest: None MaxRecvDataSegmentLength: 262144 MaxXmitDataSegmentLength: 262144 FirstBurstLength: 65536 MaxBurstLength: 262144 ImmediateData: Yes InitialR2T: Yes MaxOutstandingR2T: 1 ************************ Attached SCSI devices: ************************ Host Number: 7 State: running scsi7 Channel 00 Id 0 Lun: 0 Attached scsi disk sdb State: running scsi7 Channel 00 Id 0 Lun: 1 Attached scsi disk sdc State: running 2. vdsm.log errors: 2020-11-27 18:37:16,786+0100 INFO (jsonrpc/0) [api] FINISH getStats error=Virtual machine does not exist: {'vmId': 'f3a1194d-0632-43c6-8e12-7f22518cff87'} (api:129) ..... 2020-11-27 18:37:52,864+0100 INFO (jsonrpc/4) [vdsm.api] FINISH getVolumeInfo error=(-223, 'Sanlock resource read failure', 'Lease does not exist on storage') from=::1,60880, task_id=138a3615-d537-4e5f-a39c-335269ad0917 (api:52) 2020-11-27 18:37:52,864+0100 ERROR (jsonrpc/4) [storage.TaskManager.Task] (Task='138a3615-d537-4e5f-a39c-335269ad0917') Unexpected error (task:880) Traceback (most recent call last): File "/usr/lib/python3.6/site-packages/vdsm/storage/task.py", line 887, in _run return fn(*args, **kargs) File "<decorator-gen-159>", line 2, in getVolumeInfo File "/usr/lib/python3.6/site-packages/vdsm/common/api.py", line 50, in method ret = func(*args, **kwargs) File "/usr/lib/python3.6/site-packages/vdsm/storage/hsm.py", line 3142, in getVolumeInfo info = self._produce_volume(sdUUID, imgUUID, volUUID).getInfo() File "/usr/lib/python3.6/site-packages/vdsm/storage/volume.py", line 258, in getInfo leasestatus = self.getLeaseStatus() File "/usr/lib/python3.6/site-packages/vdsm/storage/volume.py", line 203, in getLeaseStatus self.volUUID) File "/usr/lib/python3.6/site-packages/vdsm/storage/sd.py", line 549, in inquireVolumeLease return self._domainLock.inquire(lease) File "/usr/lib/python3.6/site-packages/vdsm/storage/clusterlock.py", line 464, in inquire sector=self._block_size) sanlock.SanlockException: (-223, 'Sanlock resource read failure', 'Lease does not exist on storage') 2020-11-27 18:37:52,865+0100 INFO (jsonrpc/4) [storage.TaskManager.Task] (Task='138a3615-d537-4e5f-a39c-335269ad0917') aborting: Task is aborted: "value=(-223, 'Sanlock resource read failure', 'Lease does not exist on storage') abortedcode=100" (task:1190) 3. supervdsm.log MainProcess|monitor/de4645f::DEBUG::2020-11-27 18:41:25,286::commands::153::common.commands::(start) /usr/bin/taskset --cpu-list 0-11 /usr/sbin/dmsetup remove de4645fc--f379--4837--916b--a0c2b89927d9-dfa4e933--2b9c--4057--a4c5--aa4485b070e9 (cwd None) MainProcess|monitor/de4645f::DEBUG::2020-11-27 18:41:25,293::commands::98::common.commands::(run) FAILED: <err> = b'device-mapper: remove ioctl on de4645fc--f379--4837--916b--a0c2b89927d9-dfa4e933--2b9c--4057--a4c5--aa4485b070e9 failed: Device or resource busy\nCommand failed.\n';

[ANN] oVirt 4.4.4 Third Release Candidate is now available for testing
by Sandro Bonazzola 27 Nov '20

27 Nov '20

oVirt 4.4.4 Third Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.4 Third Release Candidate for testing, as of November 26th, 2020. This update is the fourth 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 or later 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 4.4.4 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 4.4.4 (redeploy in case of already being on 4.4.4). 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. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.2 or newer * CentOS Linux (or similar) 8.2 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.2 or newer * CentOS Linux (or similar) 8.2 or newer * oVirt Node 4.4 based on CentOS Linux 8.2 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available for CentOS Linux 8 - oVirt Node NG is already available for CentOS Linux 8 Additional Resources: * Read more about the oVirt 4.4.4 release highlights: http://www.ovirt.org/release/4.4.4/ * Get more oVirt project updates on Twitter: https://twitter.com/ovirt * Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] http://www.ovirt.org/release/4.4.4/ [2] http://resources.ovirt.org/pub/ovirt-4.4-pre/iso/ -- Sandro Bonazzola MANAGER, SOFTWARE ENGINEERING, EMEA R&D RHV Red Hat EMEA <https://www.redhat.com/> sbonazzo(a)redhat.com <https://www.redhat.com/> *Red Hat respects your work life balance.

"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"

VM memory decrease
by Erez Zarum 26 Nov '20

26 Nov '20

I have an 8 node cluster running oVirt 4.4.2, i have noticed lately that some VMs started to have their memory decrease. For example a VM that was configured to have 32GB memory without any notice were had their memory decrease to about 4GB, if i restart the VM the VM comes up with the correct memory but shortly after it decreases again. The VM configuration has: Memory Size: 32768 MB Maximum Memory: 131072 MB Physical Memory Guaranteed: 1024 MB It's worth mentioning that those are Linux VMs which are provisioned through Foreman, Windows VMs are not provisioned from Foreman and their "Memory Size" is identical to "Physical Memory Guaranteed", so far i have not observed a Windows VM with this behaviour, though there might be some that i haven't caught. Is there a possibility the cause for this issue is by having "Physical Memory Guaranteed" set to this low?

Check multipath status using API
by Paulo Silva 26 Nov '20

26 Nov '20

Hi, Is it possible to check the multipath status using the current REST API on ovirt? There is an old page that hints at this but I'm not sure if this has been implemented: https://www.ovirt.org/develop/release-management/features/storage/multipath… Thanks -- Paulo Silva <paulojjs(a)gmail.com>

Connecting OVN network to physical network
by Alex K 26 Nov '20

Hi all, I have created some logical switches at the OVN network provider (the default provider that is configured during engine-setup). This is working fine. I would like though to be able to connect a logical OVN switch to a physical network at which the hosts have access, so as to give access to guest VMs to this network. When connecting such switch to a physical network the guest VMs do not have access to the physical network: [image: image.png] It seems that this should be supported from ovirt. Am I missing something? P.S. I know I can provide such connectivity through standard networking, though was wondering if this can be done with OVN. Many thanx, Alex

Re: EPYC CPU not being detected correctly on cluster
by Lucia Jelinkova 25 Nov '20

Hi Vinícius, Thank you for the libvirt output - libvirt marked the EPYC CPU as not usable. Let's query qemu why that is. You do not need an oVirt VM to do that, just any VM running on qemu, e.g. created by Virtual Machines Manager or you can follow the command from the answer here: https://unix.stackexchange.com/questions/309788/how-to-create-a-vm-from-scr… Then you can use the following commands: sudo virsh list --all sudo virsh qemu-monitor-command [your-vm's-name] --pretty '{"execute":"query-cpu-definitions"}' I do not know if this could be related to UEFI Firmware, lets check the qemu output first.

https://www.ovirt.org/documentation/administration_guide/#Designate_a_Speci… documents how to use a display network. A possible flow could be like this: 1. Create a new logical network, use a VLAN if you do not have a free NIC on every host 2. Attach the new logical network and attach it in Compute > Hosts > hostname > Network Interfaces > Setup Host Networks to a free NIC (or an already used one if the network has a VLAN) for every host.

Ovirt 4.4.3 Hyper-converged Deployment with GlusterFS
by rcpoling＠gmail.com 24 Nov '20

24 Nov '20

Trying to deploy a 3 Node Hyperconverged Ovirt Cluster with Gluster as the backend storage. I have tried this against the three nodes that I have as well as with just a single node to get a working base line. The failure that I keep getting stuck on is: TASK [gluster.infra/roles/backend_setup : Create volume groups] **************** task path: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/vg_create.yml:59 failed: [ovirt01-storage.poling.local] (item={'key': 'gluster_vg_sdb', 'value': [{'vgname': 'gluster_vg_sdb', 'pvname': '/dev/sdb'}]}) => {"ansible_loop_var": "item", "changed": false, "err": " Device /dev/sdb excluded by a filter.\n", "item": {"key": "gluster_vg_sdb", "value": [{"pvname": "/dev/sdb", "vgname": "gluster_vg_sdb"}]}, "msg": "Creating physical volume '/dev/sdb' failed", "rc": 5} I have verified my dns records and have reverse dns set up. The Front End Network and Storage Networks are physical separated and are 10GB connections. In the reading i have done this seems to point to possibly being a multipath issue, but i do see multipath configs being set in the Gluster Wizard and when I check after the wizard fails out - it does look like the mpath is set correctly.

bond or different networks for frontend and backend
by jb 24 Nov '20

24 Nov '20

Hello, here in the description (https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_node…) it says that we should have at least 2 interfaces to separate frontend and backend traffic. How is this when I have 4 nics and I make with all one bond interface, is this not better in terms of performance? What is your recommendation with 4 x 1Gbit nics? Best regards Jonathan

Replacing ovirt certificates issue
by Alex K 24 Nov '20

24 Nov '20

Hi all, I am trying to replace the ovirt certificate at ovirt 4.3 following this: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.3/ht… I am doing the following: I have engine FQDN: manager.lab.local 1. Create root CA private key: openssl genrsa -des3 -out root.key 2048 2. Generate root certificate: (enter passphrase of root key) openssl req -x509 -new -nodes -key root.key -sha256 -days 3650 -out root.pem cp root.pem /tmp 3. Create key and CSR for engine: openssl genrsa -out manager.lab.local.key 2048 openssl req -new -out manager.lab.local.csr -key manager.lab.local.key 4. Generate a certificate for engine and sign with the root CA key: openssl x509 -req -in manager.lab.local.csr \ -CA root.pem \ -CAkey root.key \ -CAcreateserial \ -out manager.lab.local.crt \ -days 3650 \ -sha256 \ -extensions v3_req 5. Verify the trust chain and check the certificate details: openssl verify -CAfile root.pem manager.lab.local.crt openssl x509 -text -noout -in manager.lab.local.crt | head -15 6. Generate a P12 container: (with empty password) openssl pkcs12 -export -out /tmp/apache.p12 \ -inkey manager.lab.local.key \ -in manager.lab.local.crt 8. Export key and cert: openssl pkcs12 -in apache.p12 -nocerts -nodes > /tmp/apache.key openssl pkcs12 -in apache.p12 -nokeys > /tmp/apache.cer From the above steps we should have the following: /tmp/root.pem /tmp/apache.p12 /tmp/apache.key /tmp/apache.cer 9. Place the certificates: hosted-engine --set-maintenance --mode=global cp -p /etc/pki/ovirt-engine/keys/apache.p12 /tmp/apache.p12.bck cp /tmp/apache.p12 /etc/pki/ovirt-engine/keys/apache.p12 cp /tmp/root.pem /etc/pki/ca-trust/source/anchors update-ca-trust rm /etc/pki/ovirt-engine/apache-ca.pem cp /tmp/root.pem /etc/pki/ovirt-engine/apache-ca.pem Backup existing key and cert: cp /etc/pki/ovirt-engine/keys/apache.key.nopass /etc/pki/ovirt-engine/keys/apache.key.nopass.bck cp /etc/pki/ovirt-engine/certs/apache.cer /etc/pki/ovirt-engine/certs/apache.cer.bck cp /tmp/apache.key /etc/pki/ovirt-engine/keys/apache.key.nopass cp /tmp/apache.cer /etc/pki/ovirt-engine/certs/apache.cer chown root:ovirt /etc/pki/ovirt-engine/keys/apache.key.nopass chmod 640 /etc/pki/ovirt-engine/keys/apache.key.nopass systemctl restart httpd.service 10.

Edit /etc/ovirt-imageio-proxy/ovirt-imageio-proxy.conf: vi /etc/ovirt-imageio-proxy/ovirt-imageio-proxy.conf # Key file for SSL connections ssl_key_file = /etc/pki/ovirt-engine/keys/apache.key.nopass # Certificate file for SSL connections ssl_cert_file = /etc/pki/ovirt-engine/certs/apache.cer 13. Import the certificate at system-wide java trust store update-ca-trust extract keytool -list -alias ovirt -keystore /etc/pki/java/cacerts 14. Restart services: systemctl restart httpd.service systemctl restart ovirt-provider-ovn.service systemctl restart ovirt-imageio-proxy systemctl restart ovirt-websocket-proxy systemctl restart ovirt-engine.service Following the above I get at engine GUI: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I have tried also to run engine-setup in case it could fix anything (it renewed the cert due to missing subjectAltName), and the above error still persists. I have tried several other suggestions from similar issues reported at this list without any luck. I have run out of ideas. Am I missing anything? Thanx for any suggestions. Alex

oVirt Engine LDAP aaa - rfc2307bis issues
by Jake R 23 Nov '20

23 Nov '20

Hi, I have LDAP with rfc2307bis schema - I have posixGroup, with members defined as FDNs under the member attribute. Currently, if I login to oVirt via the AAA extension. then my groups are not enumerated. The LDAP searches (recorded on the LDAP server) are: slapd[1503]: conn=7876 op=2 SRCH base="dc=example,dc=com" scope=2 deref=0 filter="(&(objectClass=posixGroup)(memberUid=jreynolds))" slapd[1503]: conn=7876 op=2 SRCH attr=entryUUID cn description slapd[1503]: conn=7871 op=2 SRCH base="dc=example,dc=com" scope=2 deref=0 filter="(&(|(objectClass=groupOfUniqueNames)(objectClass=posixGroup))(uniqueMember:uniqueMemberMatch:=cn=jreynolds,ou=users,dc=example,dc=com))" slapd[1503]: conn=7871 op=2 SRCH attr=entryUUID cn description This returns no results, as the search needs to search for 'member' attribute, with an FDN. The issue looks to be inherited from the simple.properties file (regardless of if I use rfc2307, rfc2307-openldap profile), with the line: search.simple-resolve-groups-member.search-request.filter = &${seq:simple_filterGroupObject}(${seq:simple_attrGroupMemberDN}=${seq:_simple_dn_encoded}) I can fix the issue by replacing "${seq:simple_attrGroupMemberDN}=" with "member=", but this feels pretty hacky. I cannot find where this variable is defined, nor how to change it. Is the correct way to do this to create a new profile that overwrites the filter value? Or am I doing something wrong? I don't think my LDAP schema is particularly unusual, as far as I'm aware it complies with rfc2307bis spec. Thanks, Jake

Best and clean way to have oVirt qemu and libvirt versions on CentOS 8
by Gianluca Cecchi 22 Nov '20

22 Nov '20

Hello, normally with current CentOS 8.2 I get qemu-kvm-core-15:2.12.0-99.module_el8.2.0+524+f765f7e0.4.x86_64 libvirt-daemon-4.5.0-42.module_el8.2.0+320+13f867d7.x86_64 With oVirt 4.4 having qemu-kvm-core-4.2.0-29.el8.3.x86_64 libvirt-daemon-6.0.0-25.2.el8.x86_64 and in current Fedora 32 updates: qemu-kvm-core-4.2.1-1.fc32.x86_64.rpm libvirt-daemon-6.1.0-4.fc32.x86_64.rpm I see on CentOS these groups somehow related to Virtualization: Virtualization Host Virtualization Client Virtualization Hypervisor Virtualization Platform Virtualization Tools What could be the best and less intrusive repo to enable on plain CentOS 8.2 to get qemu-kvm and libvirt versions quite similar to oVirt shipped ones, or fedora ones, without enabling all the ovirt 4.4 repos? Thanks, Gianluca

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?

Re: Fix corrupt self-hosted engine
by Alex K 22 Nov '20

For the records, After having fixed the major fs issues with guestfish and since the DB was not starting up, I removed everything from DB data dir and recreated it as below: rm -rf /var/opt/rh/rh-postgresql10/lib/pgsql/data/* /opt/rh/rh-postgresql10/root/usr/bin/postgresql-setup --initdb systemctl restart rh-postgresql10-postgresql.service Then proceeded with the restoration, where I requested to provision all missing databases: engine-backup --mode=restore --file=engine-backup.gz --provision-all-databases \ --log=restore.log --restore-permissions Following this, ran engine-setup, as instructed from the restore operation. Gained engine web access and saw the same running VMs were shown as up without issues. I only observed one VM not able to start due to illegal volume, but that's another story.

Found a host rebooting - ways to watch?
by Chris Adams 20 Nov '20

20 Nov '20

I just noticed that one of my oVirt physical hosts has been rebooting due to an apparent hardware voltage fault. It's a Dell, and I've got their tools installed and am monitoring status, but the issue clears itself. It has apparently been doing this for a bit now, and we didn't catch it because (a) there weren't any VMs on it (probably were the first time but they were restarted elsewhere fast enough that it wasn't noticed) and (b) it reboots fast enough that at most it pops up in our monitoring system for one pass and then clears so our NOC either didn't see it or assumed it was okay since it cleared. oVirt has been logging alerts when it happens, but seeing that requires someone to log in and check the logs (and we've got a bunch of different systems to manage, including multiple oVirt clusters, so nobody is doing that on a regular basis). We monitor most things with SNMP and/or CLI checks (we have PRTG, Nagios, and LibreNMS for various different things). What are people doing to monitor the health of their oVirt systems? Is it possible to get alerts emailed to admins? Is there any SNMP support in oVirt to allow external systems to monitor its health? This setup is on 4.3.10 if that matters. -- Chris Adams <cma(a)cmadams.net>

Re: EPYC CPU not being detected correctly on cluster
by Lucia Jelinkova 20 Nov '20

20 Nov '20

Hi, oVirt CPU detection depends on libvirt (and that depends on qemu) CPU models. Could you please run the following command to see what libvirt reports? virsh domcapabilities That should give you the list of CPUs known to libvirt with a usability flag for each CPU. If you find out that the CPU is not usable by libvirt, you might want to dig deeper by querying quemu directly. Locate any VM running on the system by sudo virsh list --all Use the name of a VM in the following command: sudo virsh qemu-monitor-command [your-vm's-name] --pretty '{"execute":"query-cpu-definitions"}' That would give you the list of all CPUs supported by qemu and it will list all cpu's features that are not available on your system.

Upgrade hyperconverged self-hosted ovirt from 4.3 to 4.4
by ralf＠os-s.de 20 Nov '20

20 Nov '20

Hi, has anyone attempted an upgrade from 4.3 to 4.4 in a hyperconverged self-hosted setup? The posted guidelines seem a bit contradictive and not complete. Has anyone tried it and could share his experiences? I am currently having problems when deploying the hosted engine and restoring. The host becomes unresponsive and has hung tasks. Kind regards, Ralf

Can't use ovirt web interface (500 error)
by lorenzobarbati02＠gmail.com 20 Nov '20

20 Nov '20

Hi, After updating to the latest version of ovirt (standalone installed with engine-setup) I am no longer able to use the web ui. After I log in, in fact, I get a modal error entitled "operation canceled" and with content "a request to the server failed, error 500" Looking at the requests it actually receives an error 500 when it goes to make a request to "/ovirt-engine/webadmin/GenericApiGWTService" which replies "The call failed on the server; see server log for details" These are the last lines of the engine.log: https://pastebin.com/uFgZASuW Is anyone experiencing the same problem or know how to fix it?

How do you manage OVN?
by Alex McWhirter 20 Nov '20

20 Nov '20

I'm not sure if I' missing something, but it seems there is no way built in to oVirt to manage OVN outside of network / subnet creation. In particular routing both between networks and to external networks. Of course you have the OVN utilities, but it seems that the provider API is the preffered method of interaction? As far as i can tell, the only utility that can use this API as intended is ManageIQ, which is a bit a behemoth if you only need the OVN portion of things. So is that it then? Interface with the API directly or use ManageIQ? Just curious what others are doing in regards to OVN.

EPYC CPU not being detected correctly on cluster
by Vinícius Ferrão 19 Nov '20

19 Nov '20

Hi I've an strange issue with two hosts (not using the hypervisor image) with EPYC CPUs, on the engine I got this message: The host CPU does not match the Cluster CPU Type and is running in a degraded mode. It is missing the following CPU flags: model_EPYC. Please update the host CPU microcode or change the Cluster CPU Type.

[ANN] oVirt 4.4.4 Second Release Candidate is now available for testing
by Lev Veyde 19 Nov '20

19 Nov '20

oVirt 4.4.4 Second Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.4 Second Release Candidate for testing, as of November 19th, 2020. This update is the fourth 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 or later 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 4.4.4 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 4.4.4 (redeploy in case of already being on 4.4.4). 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. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.2 or newer * CentOS Linux (or similar) 8.2 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.2 or newer * CentOS Linux (or similar) 8.2 or newer * oVirt Node 4.4 based on CentOS Linux 8.2 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed.

Self Hosted Engine a single Bare Metal Server
by LS CHENG 19 Nov '20

19 Nov '20

Hi We are planning to set up a single ovirt node for testing. It is a single Bare Metal Server. I wonder if there is any problem setting up a Self Hosted Engine in this Bare Metal (there is no HA but we don't need it in this case)? I know it is probably not the best practice but it is for training and testing purposes. Thank you

Fix corrupt self-hosted engine
by Alex K 19 Nov '20

19 Nov '20

Hi all, I have a corrupt self-hosted engine (with several file system errors, postgres not able to start) and thus it does not give access to the web UI. This happened following an unlucky split brain resolution (I am running 2 nodes). The two hosts are running VMs also which I would like to keep running as they are needed. When trying to boot into rescue mode (using systemd.unit=emergency.target boot parameter) I get a cursor and nothing else. I have backups of engine files with scope all (using the engine-backup tool). What is the best approach to try and fix the engine or redeploy. Thanks for any help. Alex

Hi, I installed a new server, using the ovirt iso, with the target of migrating the VMs coming from another cluster, contained on another ovirt node. I tried to migrate a vm using the Export Domain, once imported on the new node, i see the vm from web dashboard but, from command line “virsh list --all” is absent, the imported vm does not appear in the list. Also if I try to start it, I get the following error: VM X is down with error. Exit message: unsupported configuration: bus must be 0 for ide controller. Can you help me?

Hi Bradley, usually this is not supposed to happen. I can propose you a fast fix: - Set a node into maintenance (via the UI) and then from the "Installation" drop down menu (upper right) click "reinstall" There is a tab for the HostedEngine and you have to mark it as deployed/installed If it doesn't work,ssh to one of the hosts and provide the output of: hosted-engine --vm-status Best Regards В сряда, 18 ноември 2020 г., 08:08:36 Гринуич+2, McNamara, Bradley <bradley.mcnamara(a)seattle.gov> написа: I'm new to oVirt, but not new to virtualization technologies.

Thanks. :-) > If you go in Compute --> Hosts in web admin gui, do the added hosts have a crown icon on the left of their "Name" column? If not, when you added them possibly you overlooked the "Hosted Engine" section in the window, where by default, if I'm not wrong, the value is "None": that means that the added host doesn't contributed to be one of the "Hosted Engine" ones electable to host the engine VM, but only an hyoervisor. Long time ago I opened two bugzillas about this default with some notes for improving a better experience.... If this is the case, you can remove the hosts one by one and add them again selecting "Deploy" in the Hosted Engine section, for how many you would like to contribute to the score and to be able to host the hosted engine VM.

Hosted Engine can't migrate
by McNamara, Bradley 17 Nov '20

17 Nov '20

I'm new to oVirt, but not new to virtualization technologies. I've run into a wall, but the solution has gotta be simple. I've seen other threads with the same issue, but a solution is never posted. I've followed the guide perfectly. I get the self-hosted engine up and running with no issues. I add hosts to the cluster, but it won't let me migrate the HE because of Hosted Engine HA score of "N/A" on every host except the one it was initially deployed on. The physical servers are exactly the same: same networks, storage, OS, patches, etc. The additional hosts are added thru the HE GUI and are added without issue. Is there a secret button I gotta push? What am I missing? This is with 4.3 on CentOS 7.9. HELP! Thanks. :-)

ovirt-shell SSL Error
by FRIES, Dirk, SHS Informatik 17 Nov '20

17 Nov '20

Hello there, I am trying to connect via ovirt-shell to my ovirt manager. To do this I've downloaded the CA File (https://127.0.0.1/ovirt-engine/services/pki-resource?resource=ca-certificat…) to /tmp and set up my config in .ovirtshellrc : [cli] autoconnect = True autopage = True [ovirt-shell] username = adminuser renew_session = False timeout = None extended_prompt = False url = https://127.0.0.1/api insecure = False kerberos = False filter = False session_timeout = None ca_file = /tmp/pki-resource?resource=ca-certificate dont_validate_cert_chain = True key_file = None password = somepassword cert_file = None So when I am trying to connect I get the following error: (60, "Peer's certificate issuer has been marked as not trusted by the user.") While researching I also found a pretty similar issue here https://lists.ovirt.org/archives/list/users@ovirt.org/thread/IYG6AQPII25366… but unfortunally there is no solution posted. Does anyone have a hint for me what could cause this problem or where to look else ? Thanks a lot ! Bye, Dirk

Re: VM with illegal snapshots
by Florian Schmid 17 Nov '20

17 Nov '20

Hi, I have also sometimes the issue with snapshots or disk move, which is also related to snapshots, when the engine process is running for a longer time. After restarting the engine service, then it is working again for several weeks, until it gets too long and issues starting again to happen. I had never the time to dig in deeper here and I'm never on a version, which is still supported, but it would be nice to here, if you maybe have the same issue? How long was your engine process running, until the issues have started?

November 2020 10:37:24 Betreff: [ovirt-users] Re: VM with illegal snapshots Hello We have the same issue, and not just one VM, we have about 10-15 VMs that have either snapshots that are illegal or snapshots that is not possible to remove. This have been an issue for quite some time, all since beginning of 4.3 we get "vm with illegal snapshots" almost every week, and most often we can remove the snapshot and all is ok, but now this have escalated quite much and leaves us with customer VM that we may not be able to reboot or that the disk gets corrupted, that have happed a few times. This is the VM with most snapshots that we are unable to remove any of them. Engine is on 4.3.10 and hosts on 4.3.9 How can i safely remove these snapshots? (I am not super comfortable around database "hacking" so some informative description would be much appreciated.) And how can we eliminate that these things happen?

VM with illegal snapshots

Hi, due to a bug in our Ovirt integrated backup system now we have some VMs with snapshots in illegal state. It seems that there's an inconsistency between the db and the real status of images on disk. Let me show an example: engine=# select image_guid,parentid,imagestatus,vm_snapshot_id,volume_type,volume_format,active from images where image_group_id='e34f77cb-54d5-40d0-b539-e0a5fd512d2d'; image_guid | parentid | imagestatus | vm_snapshot_id | volume_type | volume_format | active --------------------------------------+--------------------------------------+-------------+--------------------------------------+-------------+---------------+-------- a107b6c4-842e-4b40-9215-c965431a0c0f | 00000000-0000-0000-0000-000000000000 | 4 | d19d6ca3-1989-4c67-8ee7-c0c43b3e6d74 | 2 | 4 | f a4c86a68-9123-454c-b417-1b15038a4bf2 | a107b6c4-842e-4b40-9215-c965431a0c0f | 1 | e7a405ee-8fd4-4733-ae9c-5252bf07c9d3 | 2 | 4 | f f6a61f2e-26bd-4b63-97c6-d66913ce48c5 | a4c86a68-9123-454c-b417-1b15038a4bf2 | 1 | 9d0958b9-4995-4e11-a027-a32d4bac52e4 | 2 | 4 | t (3 rows) [root@host02 ~]# lvs -o+lv_tags |grep e34f77cb-54d5-40d0-b539-e0a5fd512d2d a107b6c4-842e-4b40-9215-c965431a0c0f 459011cf-ebb6-46ff-831d-8ccfafd82c8a -wi------- 149.50g IU_e34f77cb-54d5-40d0-b539-e0a5fd512d2d,MD_68,PU_00000000-0000-0000-0000-000000000000 f6a61f2e-26bd-4b63-97c6-d66913ce48c5 459011cf-ebb6-46ff-831d-8ccfafd82c8a -wi------- 10.00g IU_e34f77cb-54d5-40d0-b539-e0a5fd512d2d,MD_348,PU_a107b6c4-842e-4b40-9215-c965431a0c0f so image guid a4c86a68-9123-454c-b417-1b15038a4bf2 is not present on disk, i think that the image was correctly merged but not removed from the database.
