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

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.

oVirt host deploy: disable multipath

by femi adegoke

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

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

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-...). 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%20Enterp... 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?

OVS switch type for hosted-engine

by Devin A. Bougie

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

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?

OVN routing and firewalling in oVirt

by Gianluca Cecchi

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

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

OVN and change of mgmt network

by Gianluca Cecchi

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

"gluster-ansible-roles is not installed on Host" error on Cockpit

by Hesham Ahmed

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"

deprecating export domain?

by Charles Kozler

Hello, I recently read on this list from a redhat member that export domain is either being deprecated or looking at being deprecated To that end, can you share details? Can you share any notes/postings/bz's that document this? I would imagine something like this would be discussed in larger audience This seems like a somewhat significant change to make and I am curious where this is scheduled? Currently, a lot of my backups rely explicitly on an export domain for online snapshots, so I'd like to plan accordingly Thanks!

Hi Leo, As you do not have a distributed volume , you can easily switch to replica 2 arbiter 1 or replica 3 volumes.

How to connect to a guest with vGPU ?

by Josep Manel Andrés Moscardó

Hi, I got vGPU through mdev working but I am wondering how I would connect to the client and make use of the GPU. So far I try to access the console through SPICE and at some point in the boot process it switches to GPU and I cannot see anything else. Thanks. -- Josep Manel Andrés Moscardó Systems Engineer, IT Operations EMBL Heidelberg T +49 6221 387-8394

Vm suddenly paused with error "vm has paused due to unknown storage error"

by Jasper Siero

Hi all, Since we upgraded our Ovirt nodes to CentOS 7 a vm (not a specific one but never more then one) will sometimes pause suddenly with the error "VM ... has paused due to unknown storage error". It happens now two times in a month. The Ovirt node uses san storage for the vm's running on it. When a specific vm is pausing with an error the other vm's keeps running without problems. The vm runs without problems after unpausing it.

Ovirt-engine-ha cannot to see live status of Hosted Engine

by asm＠pioner.kz

Good day for all. I have some issues with Ovirt 4.2.6. But now the main this of it: I have two Centos 7 Nodes with same config and last Ovirt 4.2.6 with Hostedengine with disk on NFS storage. Also some of virtual machines working good. But, when HostedEngine running on one node (srv02.local) everything is fine. After migrating to another node (srv00.local), i see that agent cannot to check livelinness of HostedEngine. After few minutes HostedEngine going to reboot and after some time i see some situation.

But, installation was unsuccesfull, before i didnt install ovirt-hosted-engine-ha on this node. I dont see in documentation that its need bofore installation of new hosts. But this is for information and checking. After installing ovirt-hosted-engine-ha node was installed with HostedEngine support. But the main issue not changed. Thanks in advance for help.

Hyperconverged setup - storage architecture - scaling

by Leo David

Hello Everyone, Reading through the document: "Red Hat Hyperconverged Infrastructure for Virtualization 1.5 Automating RHHI for Virtualization deployment" Regarding storage scaling, i see the following statements: *2.7. SCALINGRed Hat Hyperconverged Infrastructure for Virtualization is supported for one node, and for clusters of 3, 6, 9, and 12 nodes.The initial deployment is either 1 or 3 nodes.There are two supported methods of horizontally scaling Red Hat Hyperconverged Infrastructure for Virtualization:* *1 Add new hyperconverged nodes to the cluster, in sets of three, up to the maximum of 12 hyperconverged nodes.* *2 Create new Gluster volumes using new disks on existing hyperconverged nodes.You cannot create a volume that spans more than 3 nodes, or expand an existing volume so that it spans across more than 3 nodes at a time* *2.9.1. Prerequisites for geo-replicationBe aware of the following requirements and limitations when configuring geo-replication:One geo-replicated volume onlyRed Hat Hyperconverged Infrastructure for Virtualization (RHHI for Virtualization) supports only one geo-replicated volume. Red Hat recommends backing up the volume that stores the data of your virtual machines, as this is usually contains the most valuable data.* ------ Also in oVirtEngine UI, when I add a brick to an existing volume i get the following warning: *"Expanding gluster volume in a hyper-converged setup is not recommended as it could lead to degraded performance. To expand storage for cluster, it is advised to add additional gluster volumes." * Those things are raising a couple of questions that maybe for some for you guys are easy to answer, but for me it creates a bit of confusion... I am also referring to RedHat product documentation, because I treat oVirt as production-ready as RHHI is. *1*. Is there any reason for not going to distributed-replicated volumes ( ie: spread one volume across 6,9, or 12 nodes ) ? - ie: is recomanded that in a 9 nodes scenario I should have 3 separated volumes, but how should I deal with the folowing question *2.* If only one geo-replicated volume can be configured, how should I deal with 2nd and 3rd volume replication for disaster recovery *3.* If the limit of hosts per datacenter is 250, then (in theory ) the recomended way in reaching this treshold would be to create 20 separated oVirt logical clusters with 12 nodes per each ( and datacenter managed from one ha-engine ) ? *4.* In present, I have the folowing one 9 nodes cluster , all hosts contributing with 2 disks each to a single replica 3 distributed replicated volume. They where added to the volume in the following order: node1 - disk1 node2 - disk1 ...... node9 - disk1 node1 - disk2 node2 - disk2 ...... node9 - disk2 At the moment, the volume is arbitrated, but I intend to go for full distributed replica 3. Is this a bad setup ? Why ? It oviously brakes the redhat recommended rules... Is there anyone so kind to discuss on these things ? Thank you very much !

ovirt-imagio-proxy upload speed slow

by Dev Ops

I am working on integrating a backup solution for our ovirt environment and having issues with the time it takes to backup the VM's. This backup solution is simply taking a snapshot and making a clone and backing the clone up to a backup server. A VM that is 100 gig takes 52 minutes to back up. The same VM doing a file backup using the same product, and bypassing their rhv plugin, takes 14 minutes. So the throughput is there but the ovirt imageio-proxy process seems to be what manages how images are uploaded and is officially my bottle neck. Load is not high on the engine or kvm hosts. I had bumped up the Upload image size from 100MB to 10gig weeks ago and that didn't seem to help. [root@blah-lab-engine ~]# engine-config -a |grep Upload UploadImageChunkSizeKB: 10240000 version: general [root@bgl-vms-engine ~]# rpm -qa |grep ovirt-image ovirt-imageio-proxy-1.4.6-1.el7.noarch ovirt-imageio-common-1.4.6-1.el7.x86_64 ovirt-imageio-proxy-setup-1.4.6-1.el7.noarch I have seen bugs reported to redhat about this but I am running above the affected releases. engine software is 4.2.8.2-1.el7 Any idea what we can tweak to open up this bottleneck?

Hosted-engine inaccessible

by Tau Makgaile

Hi, I am currently experiencing a problem with my Hosted-engine. Hosted-engine disconnected after increasing / partition. The increase went well but after some time the hosted-enigine VM disconnected and has since been giving alerts such as* re-initializingFSM*. Though VMs underneth are running, Hosted-engine --vm-status: *"reason": "failed liveliness check", "health": "bad", "vm": "up", "detail"* There is no backup to restore at the moment. I am looking for a way to bring it up without redeploying the hosted engine. Thanks in advance for your help. Kind regards, Tau

oVirt 3.6: Node went into Error state while migrations happening

by Christopher Cox

On the node in question, the metadata isn't coming across (state) wise. It shows VMs being in an unknown state (some are up and some are down), some show as migrating and there are 9 forever hung migrating tasks. We tried to bring up some of the down VMs that had a state of Down, but that ended up getting them the state of "Wait for Lauch", though those VMs are actually started. Right now, my plan is attempt a restart of vdsmd on the node in question. Just trying to get the node to a working state again. There a total of 9 nodes in our cluster, but we can't manage any VMs on the affected node right now. Is there a way in 3.6 to cancel the hung tasks? I'm worried that if vdsmd is restarted on the node, the tasks might be "attempted"... I really need them to be forgotten if possible. Ideally want all "Unknown" to return to either an "up" or "down" state (depending if the VM is up or down) and for "Wait for Launch" for those, to go to "up" and for all the "Migrating" to go to "up" or "down" (I think only one is actually down). I'm concerned that any attempt manually maniplate the state in the ovirt mgmt head db will be moot because the node will be queried for state and that state will be taken and override anything I attempt to do. Thoughts??

hosted engine installation / multipath / iscsi

by Michael Frank

Hi, since several days i try to install the hosted engine initially to an iscsi multipath device without success. Some information on the environment: - Version 4.3.3 - using two 10gbe interfaces as single bond for the ovirtmgmt interface - using two 10gbe storage interfaces on each hypervisor for iscsi storage -- each storage interface is configured without any bonding, etc -- each storage interface lives in a separate vlan were also the iscsi Portals/target are available, the iscsi portals have 4x10ge interfaces each, (2 in vlan xx and 2 interfaces in vlan yy ) -- so; each storage interface is connected to two iscsi Portals via 4 interfaces The documentation here is for me unclear: https://ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_En... >Note: To specify more than one iSCSI target, you must enable multipathing before deploying the self-hosted engine. There is also a Multipath >Helper tool that generates a script to install and configure multipath with different options. This indicates for me that it should be possbile to install the HE directly on the /dev/mapper/mpath device which is availibale when I have prepared the host accordingly before installing the HE (log in to multiple iscsi targets, create proper multipath,conf, etc) - right ? I login to the two iscsi portals and get in sum 8 pathes, 4 from each interface and iscsi target. Basically I have then the mpath device on the hypervisor available and i can mount the mpath device and put data on it. In the cockpit interface the mount can also be activated and is recognized correctly. multipathd -ll and lsblk looks good. Everything seems to be fine. But when I run the "hosted-engine" --deploy, the last option while running the assistant is to enter the iscsi data. So, basically i just want to define my mpath device - when entering the data (ip, port)for the iscsi Portal I can see the 4 pathes of the single hosted Engine target, and when i choose the path where the "lun" is finally available it fails. I think in general this option is not that what i want to have here for using the multipath device. I' m lost - what is the usual way to install the HE on a multipath device ? Do i have to change the configuration of the storage interfaces or the iscsi network design? Did I missed something obvious ? Can I put in my multipath data into the answerfile to get rid of the last step of the assistant ?

Data Center Compatibility version

by Rick A

So I updated our environment a bit ago during a scheduled down time from 4.2 to 4.3. Everything went smoothly, but it looks like I forgot to update the Data Center Compatibility (See alert message below). My question is, can I just change the Data Center compatibility to 4.3 while the environment is running without causing issues, or do i need to shutdown all my VM's and put the hosts into maintenance mode? The compatibility version for everything else is already set to 4.3. Thanks Alert Message: "Data Center compatibility version is 4.2, which is lower than latest engine version 4.3. Please upgrade your Data Center to latest version to successfully finish upgrade of your setup"

Use public-signed SSL certs?

by Chris Adams

I installed an SSL cert from a public CA (Let's Encrypt) on my engine, following this: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/... That gets the regular web UI working, but I can't upload an ISO. I assume that I need to do something with the imageio-proxy service on the engine, but not sure what... I tried replacing imageio-proxy.cer and imageio-proxy.key.nopass, but that didn't work. I'm trying to avoid ever needing to install a special CA cert in browsers. -- Chris Adams <cma(a)cmadams.net>

Re: Manual Migration not working and Dashboard broken after 4.3.4 update

by Strahil

I'm not sure, but I always thought that you need an agent for live migrations. You can always try installing either qemu-guest-agent or ovirt-guest-agent and check if live migration between hosts is possible. Have you set the new cluster/dc version ?

Good evening, Thanks in advance, I'm trying to set up a new VM in my cluster, and things appear to have hung up initializing the 80GB boot partition for a new Windows VM.

Moving data to new storage appliance

by David Johnson

Hi everyone, I'm sorry to bother y'all with another noob question. We are in the process of retiring the old storage appliance that backed our oVirt cluster in favor of a new appliance. I have migrated all of the active VM storage to the new appliance, but can't see how to migrate the "base versions". My understanding is that if I just drop the storage with the base versions then the derived VM's will cease to be functional. Please advise.

Great. Storage domain attached, templates imported and the only VM defined at source correctly started (at source I configured link down for the VM, inherited at target, so no collisions). Elapsed between beginning of ovirt connection, until first template import has been about 6 minutes. ...

I'm using EQL that doesn't support bonding and has one portal that all initiators use. So in my primary env I configured "iSCSI Multipathing" tab in Compute --> Datacenter --> Datacenter_Name window. But this tab appears only when you activate the storage. So during the ansible playbook run the iSCSI connection has been activated through the "default" iscsi interface I can then: - configure "iSCSI Multipathing" - shutdown VM - put host into maintenance - remove the default iSCSI session that has not been removed on host iscsiadm -m session -r 6 -u - activate host now I have: [root@ov201 ~]# iscsiadm -m session tcp: [10] 10.10.100.8:3260,1 iqn.2001-05.com.equallogic:4-771816-99d82fc59-5bdd77031e05beac-ovsd3910 (non-flash) tcp: [9] 10.10.100.8:3260,1 iqn.2001-05.com.equallogic:4-771816-99d82fc59-5bdd77031e05beac-ovsd3910 (non-flash) [root@ov201 ~]# with # multipath -l 364817197c52fd899acbe051e0377dd5b dm-29 EQLOGIC ,100E-00 size=1.0T features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='round-robin 0' prio=0 status=active |- 23:0:0:0 sdb 8:16 active undef running `- 24:0:0:0 sdc 8:32 active undef running - start vm The I do a cleanup: 1.

The mac address is the one defined in my target engine, that is different from source engine to avoid overlap of mac adresses Is this an option I can customize? In general a VM could have problems when changing its mac address... 3) Clean up dest DC after "discreet failover test" The guide says: 1. Detach the storage domains from the secondary site. 2. Enable storage replication between the primary and secondary storage domains. better to also restart the DR hosts? 4) VM consistency Can we say that all the imported VMs will be "crash consistent"? Thanks, Gianluca

Clone function seem broken - regarding disk virtual size

by Vrgotic, Marko

Dear oVirt, All our CentOS templates are “baked” with 40GB disk (sparse) QCOW. When Creating new VM from template, using Thin storage allocation: * VM is created with 40GB disk (reading from oVirt GUI) and * from OS fdisk and/or parted report 40GB disk size. * The / partition is also matching expected size When Creating VM from template, using default Clone storage allocation: * VM is created with 40GB disk (reading from oVIrt GUI) * However: * from OS fdsik and/or parted report only actual used space, which in our case is 8GB. * The / partition is matching only actual disk size, not virtual one Why is Clone not taking into account Virtual size of the Template disk? Is it intended behavior that when image is cloned from template, only actual disk size information is copied, not the virtual? Please assist. Kindly awaiting your reply. oVirt 4.3.4 with SHE and NFS based storage and Local. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic Sr. System Engineer @ System Administration m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> tel. +31 (0)35 677 4131 ActiveVideo BV Mediacentrum 3741 Joop van den Endeplein 1 1217 WJ Hilversum

Hosted Engine VM - CPU and Memory Sizing

by paul.christian.suba＠cevalogistics.com

Hi, Is there a recommended CPU and memory size for the Hosted Engine VM? We have what started as a 4 node physical cluster lab with 4 vms that has now grown to 44vms. The dashboard is slow to load information and the HE VM is consistently seen with 99% CPU with the breakdown below. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 12076 postgres 20 0 506516 276172 143772 R 99.3 1.7 206:17.15 postmaster 10337 postgres 20 0 484756 254156 144000 R 99.0 1.6 179:52.35 postmaster 38603 postgres 20 0 500068 267836 143992 S 70.1 1.6 528:04.13 postmaster 49217 postgres 20 0 468736 235484 143624 S 19.3 1.4 41:57.55 postmaster 5569 ovirt 20 0 6430912 2.3g 6368 S 1.3 14.5 894:20.75 java We used the default 4 CPU and 16 GB RAM. This is oVirt 4.3.1. I am curious to find out as well if the postgres processes using 99% CPU is normal?

Hi, Can someone tell me how to generate ovirt-engine-appliance ova file in ovirt-engine-appliance-4.3-20190610.1.el7.x86_64.rpm? I tried to import ovirt-engine-appliance ova(ovirt-engine-appliance-4.3-20190610.1.el7.ova) from ovirt-engine, but I got error as following: Failed to load VM configuration from OVA file: /var/tmp/ovirt-engine-appliance-4.2-20190121.1.el7.ova I guess ovirt-engine-appliance-4.2-20190121.1.el7.ova has more than CentOS7.6.

According to another post in the mailing list, the Engine Hosts (that has ovirt-ha-agent/ovirt-ha-broker running) is checking http://{fqdn}/ovirt-engine/services/health As the IP is changed, I think you need to check the URL before and after thr mifgration.

Active-Passive DR: mutual for different storage domains possible?

by Gianluca Cecchi

Hello, suppose I want to implement Active-Passive DR between 2 sites. Sites are SiteA and SiteB. I have 2 storage domains SD1 and SD2, that I can configure so that SD1 is active in storage array installed in SiteA with replica in SiteB and SD2 the reverse. I have 4 hosts: host1 and host2 in SiteA and host3 and host4 in SiteB. I would like to optimize compute resources and workload so that: oVirt env OV1 with ovmgr1 in SiteA (external engine) is composed by host1 and host2 and configured with SD1 oVirt env OV2 with ovmgr2 in SiteB (external engine) is composed by host3 and host4 and configured with SD2. Can I use OV2 as DR for OV1 for VMs installed on SD1 and at the same time OV1 as DR for OV2 for VMs installed on SD2? Thanks in advance, Gianluca Cecchi

iSCSI-based storages won't login to the portals with all IPs on reboot

by nicolas＠devels.es

Hi, We're running oVirt 4.3.2. Currently, we have one storage backend (cabinet) with two controllers, each of them with 2 network interfaces (4 network interfaces in total). When we added the Storage Domain, we discovered the target for each of the 4 IPs and marked the LUN so it would be added with 4 different IPs. When we put a host on maintenance, all the paths are deactivated, and when we activate it back it discovers all the 4 paths for the storage backend. However, if we reboot the host, on activation it only activates one path. We can see this running 'multipath -ll'. We can manually activate the rest of the paths using this command for each of the IPs: # iscsiadm --mode discovery --type sendtargets --portal 10.X.X.X --login However, we wonder why oVirt wouldn't log into each of the IPs upon a boot. Is there something we're missing? Can this be fixed manually? Currently we're running a script on boot that will issue the command above for each of the IPs of the cabinet. Thanks for any help!

Hi oVirt List, I have just a quick question if I should open a ticket for this or if I'm doing something wrong. I created a new VM template with specific permissions in addition to the system wide permissions. If I create a new VM with the template I notices that only system permissions are copied to the permission of the new VM. Is this the intended behavior? I was somehow under the impression that the permission from the template should have been copied to the newly created VM. Tested with Version 4.3.4.3-1.el7 Best regards Christoph

reinstallation information

by nikkognt＠gmail.com

Hi, after a blackout one host of my ovirt not working properly. I tried to Reinstall it but ends with the following error "Failed to install Host ov1. Failed to execute stage 'Closing up': Failed to start service 'vdsmd'." I tried to start manually but it not start . Now, I would like to reinstall from iso ovirt node. After I put the host is in maintenance must I remove host from the cluster (Hosts -> host1 -> Remove) or I can reinstall without remove it? If I remore it from the cluster the network configurations I lose them or not? My ovirt version is oVirt Engine Version: 4.1.9.1-1.el7.centos.

Re: Storage domain 'Inactive' but still functional

by Strahil

I forgot to mention that LVM config has to be modified in order to 'inform' local LVM stack to rely on clvmd/dlm for locking purposes. Yet, this brings abother layer of complexity which I prefer to avoid , thus I use HA-LVM on my pacemaker clusters. @Martin, Check the link from Benny and if possible check if the 2 cases are related.

USB turns off and wont come alive

by Darin Schmidt

I have 2 usb controllers installed via a riser card plugged into a M.2 slot. (Like those used for mining with GPU's). Everything works great for a long time, then my Windows 10 VM freezes and I lose all USB activity. LSPCI still sees the devices: 0a:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller 0b:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller 43:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller 44:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller I assume a and b are the same physical card as its supposed to have 2 channels each, same with 44 and 43. I tried for both 44 and 43 echo "1" > /sys/bus/pci/devices/0000\:43\:00.0/remove echo "1" > /sys/bus/pci/rescan echo "1" > /sys/bus/pci/devices/0000\:43\:00.0/reset This did not work. I cannot determine if its just the VM thats no longer seeing/using the hardware or if its the hardware itself. I wonder if its a power state thing as well? Nothing I plug into the card seems to be recognized. Any Suggestions? rebooting the VM doesnt help either. It appears the hardware is functioning, but anything you plug into it isnt being detected.

Import VM from ovirt-exported ova

by david.paning＠gmx.ch

Hello, i installed a new oVirt 4.3.4 from scratch and am attempting to restore the VMs which ran perfectly fine on my last oVirt 4.2.8, where i exported the VM to the export domain and also as an OVA file. Importing the export domain fails, which i plan to debug later. But importing the OVA file via the Administration Portal also fails with Error ID: 1153 Message: Failed to import the VM to Data Center, Cluster. The VM name is still recognised by the import routine, which tells me the file is readable... Now my questions: Is there any option to try the same from CLI, hoping to get better clues for what is going on? Are there specific log options which could give some clues? Would it be better in general to import the VM from an export-storage domain instead of using a OVA export? Any hint would highly appreciated. Best

Re: major network changes

by Strahil

Hi Carl, I think there is another thread here related to the migration to another network. As far as I know, the check liveliness try's to access the ovirt's health page. Does the new engine's ip has A/PTR record setup? Also, check the engine logs, once the HostedEngine VM is up and running.

major network changes

by carl langlois

Hi We are in a process of changing our network connection. Our current network is using 10.8.256.x and we will change to 10.16.248.x. We have a HA ovirt cluster (around 10 nodes) currently configure on the 10.8.256.x. So my question is is it possible to relocate the ovirt cluster to the 10.16.248.x. We have tried to move everything to the new network without success. All the node seem to boot up properly, our gluster storage also work properly.

Re: ovirt-engine-appliance ova

It looks like a kickstart error. Maybe a parameter in the kickstart is missing ?

Cinderlib managed block storage, ceph jewel

Re: Storage domain 'Inactive' but still functional

by Strahil

If you can give directions (some kind of history) , the dev might try to reproduce this type of issue. If it is reproduceable - a fix can be provided. Based on my experience, if something as used as Linux LVM gets broken, the case is way hard to reproduce.

Re: Storage domain 'Inactive' but still functional

by Martijn Grendelman

Hi, Thanks for the tips! I didn't know about 'pvmove', thanks. In the mean time, I managed to get it fixed by restoring the VG metadata on the iSCSI server, so on the underlying Zvol directly, rather than via the iSCSI session on the oVirt host. That allowed me to perform the restore without bringing all VMs down, which was important to me, because if I had to shut down VMs, I was sure I wouldn't be able to restart them before the storage domain was back online. Of course this is a more a Linux problem than an oVirt problem, but oVirt did cause it ;-) Thanks, Martijn. Op 19-7-2019 om 19:06 schreef Strahil Nikolov: Hi Martin, First check what went wrong with the VG -as it could be something simple. vgcfgbackup -f VGname will create a file which you can use to compare current metadata with a previous version. If you have Linux boxes - you can add disks from another storage and then pvmove the data inside the VM. Of course , you will need to reinstall grub on the new OS disk , or you won't be able to boot afterwards. If possible, try with a test VM before proceeding with important ones. Backing up the VMs is very important , because working on LVM metadata is quite risky. Last time I had such an issue , I was working on clustered LVs which got their PVs "Missing". For me , restore from VG backup fixed the issue - but that might not be always the case. Just get the vgcfgbackup's output and compare with diff or vimdiff and check what is different. Sadly, I think that this is more a Linux problem , than an oVirt problem. Best Regards, Strahil Nikolov В четвъртък, 18 юли 2019 г., 18:51:32 ч.

These are largely the same, but there are differences: * seqno = 1854 in the backup and 1865 in the actual metadata. * 3 logical volumes that are not present in the backup, but are in the actual metadata. I suspect that these are related to snapshots that were created for live storage migration, but I am not sure. In any case, I did NOT create any new disk images on this domain, so that can't be it. Now, support I wanted to try the 'pvcreate' route, then: * what would be the chances of success? Is this procedure at all advisable, or is there an alternative? * which restore file (1854 or 1865) should I use for the restore? * can I do this while the VG is in use? I tried running the command without --force, and it said 'Can't open /dev/mapper/23536316636393463 exclusively. Mounted filesystem?'. I didn't dare to try it with '--force'. I could really use some advice on how to proceed. This are about 36 VMs that have one or more disks on this domain. I could bring them down, although doing so for extended amounts of time would be problematic. I want to be careful, obviously, especially since the actual storage doesn't seem to be impacted at this time. The VMs are all still running without issue, and if I'm about to embark on a dangerous journey that could cause data loss, I need a contingency / recovery plan. Hoping someone can help...

Then, you can try a newer version of the kernel from epel repo. Also, check in the CentOS forum - maybe someone had a similar issue.

It appears the VG metadata is corrupt: /dev/mapper/23536316636393463: Checksum error at offset 2748693688832 Couldn't read volume group metadata from /dev/mapper/23536316636393463.

So, I have found some information online, that suggests that PV metadata can be fixed by recreating the PV label using the correct PVID and a backup of the LVM metadata, like so: pvcreate -u <pv_uuid> --restorefile <lvm_metadata_backup> /dev/mapper/23536316636393463 Now I have the following two files: * An LVM metadata backup of yesterday 10:35, about 6 hours before the problem occurred. * The actual metadata found on the PV at offset 2748693688832 (obtained with hexedit on the block device). These are largely the same, but there are differences: * seqno = 1854 in the backup and 1865 in the actual metadata. * 3 logical volumes that are not present in the backup, but are in the actual metadata. I suspect that these are related to snapshots that were created for live storage migration, but I am not sure. In any case, I did NOT create any new disk images on this domain, so that can't be it. Now, support I wanted to try the 'pvcreate' route, then: * what would be the chances of success? Is this procedure at all advisable, or is there an alternative? * which restore file (1854 or 1865) should I use for the restore? * can I do this while the VG is in use? I tried running the command without --force, and it said 'Can't open /dev/mapper/23536316636393463 exclusively. Mounted filesystem?'. I didn't dare to try it with '--force'. I could really use some advice on how to proceed. This are about 36 VMs that have one or more disks on this domain. I could bring them down, although doing so for extended amounts of time would be problematic. I want to be careful, obviously, especially since the actual storage doesn't seem to be impacted at this time. The VMs are all still running without issue, and if I'm about to embark on a dangerous journey that could cause data loss, I need a contingency / recovery plan. Hoping someone can help...

Storage domain 'Inactive' but still functional

Hi, For the first time in many months I have run into some trouble with oVirt (4.3.4.3) and I need some help.

assign vm traffic to a physical NIC and Storage traffic to another NIC

by Erick Perez

Hi, fresh install I have created a network called "storage" and another called "vms" and both have vlan 102 tag. Only the "vms" network have the check on "vm network". then on Compute---Hosts---hvm001---setup_host_network physical nic enp3s0f0 has ovirtmgmt and vms networks defined physical nic enp3s0f1 has storage network defined Question is how do I tell ovirt that I want the STORAGE traffic to use enp3s0f1 ? I am using NFS data domains and I cannot find a place to tell the network/physical nic my NFS traffic should use. thanks,

LDAP Group issue with rfc2307bis

by Timmi

Hi oVirt List, I'm currently working on my new oVirt setup and want to integrate it into our LDAP server. Accounts are working fine but I have problems to get the groups working correctly. The LDAP server is base on ClearOS which is using the rfc2307bis setup. Means I don't have MemberOf inside my users. The user DN is as Member inside the group. I manage that oVirt is able to read the groups while overwriting: search.rfc2307-resolve-groups-memberUid.search-request.filter = &(objectClass=posixGroup)(memberUid=${seq:_rfc2307_uid_encoded}) with search.rfc2307-resolve-groups-memberUid.search-request.filter = &(objectClass=posixGroup)(member=${seq:_rfc2307_dn}) This is working absolutely fine for my admin group in "Administrator Portal". I can asign the group to the system permission "SuperUser" and everything is working great. My problem is with the "VM Portal" I have assigned "PowerUser" rights to a quota and it is possible to login but I receive the following error in the engine.log. 2019-07-18 07:38:12,317+02 ERROR [org.ovirt.engine.core.bll.GetPermissionsForObjectQuery] (default task-5) [a6828f8b-8ded-422f-a216-5e5406d7bf20] Query execution failed due to insufficient permissions. 2019-07-18 07:38:12,319+02 ERROR [org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (default task-5) [] Operation Failed: query execution failed due to insufficient permissions. I'm able to see the group permission in the user details. So I guess that something is already working. But I guess the error is preventing me to have the "create VM" button on the "VM Portal". Would be great if someone could help me out. I'm running the latest 4.3.4 version. Best regards Christoph

Support and suggestions for 10/25 GbE cards

by Gianluca Merlo

Hello everyone, I am in the hardware selection phase for an oVirt cluster which has a requirement for 10/25 GbE connectivity. Does anyone have any advice on which adapters are better supported and working on oVirt Node? The choice I have is between: - Intel XXV710 - Mellanox ConnectX-4 It is my first foray into this tier of connectivity, so pardon the naivety of the question. I would just like to hear suggesions from the experience any of you may have had in the field, so I can be better prepared and know which kind of problems I may run into, and if choosing a specific card over the other can spare me some. Thank you in advance for your help Gianluca

hosted engine, Hyperconverged recovery

by William Kwan

Hi, I need some direction to make sure we won't make more mistake in recovering a 3-node self hosted engine with Gluster. Someone carelessly, very, wiped out the first few MB of the LVM PV on one node. We changed the quorum and brought up the Gluster and oVirt. We ran vgcfgrestore on the 'bad node' and we can run pvscan, vgscan and lvscan to see the LV's. What should I do next to prevent more damage or corrupt the glusterfs on the other two nodes? Will this work? mkfs the LV's bring up gluster run gluster sync <goodNode>? ThanksWill

VM says paused, but does not appear to be.

by Jacob Green

I have a Fibre Channel back end for my oVirt cluster, and one of my VMS is saying "paused due to lack of storage space", however I can confirm that the back end storage has plenty of space and the VM itself does not appear to be paused. I can SSH the VM and perform tasks on the VM. So I am trying to figure out why it would say that, and how to clear it. Also have 20 something other VMS on this cluster and no errors like this on those. I am running engine 4.3.3.7-1.el7 Also I do not fully understand this chart, what I can tell you is that the top storage domain is my Fibre Channel storage, and it has plenty of available space, 35%-40% free And lastly this is what a df -h looks like on the given VM. If anyone has some insight on to what might cause this let me know and ill chase it down. Thank you

Re: ovirt_disk and ubuntu issues

Moving Hosted Engine Storage

by Dan Poltawski

Hello, I've read various posts[1] on this list, but I must confess that I am still not entirely clear on the process for moving a hosted engine to a new storage domain (in my case I want to move from an existing NFS server to a new iSCSI target). Some of what i've read make me slightly concerned it's a risky operation and in my situation I am just prototyping and retaining the existing engine will be saving some time rather than mission critical. Is anyone able to outline the steps to me? thanks, Dan [1] https://lists.ovirt.org/pipermail/users/2017-June/082466.html ________________________________ The Networking People (TNP) Limited.

VM status codes

by Mitja Mihelič

Hi! We are graphing certain parameters we collect from the engine database. We use following query to get the count of running VMs: select count(*),cluster.name as cluster from vms, cluster where vms.cluster_id = cluster.cluster_id and vms.status = 1 group by cluster; It would help extremely if we knew what the numeric VM status codes mean. For example, I know that "status = 1" means the VM is running. The ones we can cause through the web interface are easy enough to figure out. But there are error states, that cannot be produced by standard use. For instance, when the event log says "VM foobar has been paused due to storage I/O problem." the following states get set in the DB (Query used: select * from vm_dynamic where vm_guid =(select vm_guid from vm_static where vm_name = 'foobar';): status | 4 exit_status | 0 pause_status | 2 guest_agent_status | 0 What do they mean? If you could point me to a table somewhere with the state descriptions it would be extremely helpful. Kind regards, Mitja Mihelič

Re: ovirt-engine-appliance ova

by Strahil

Exactly. Ovirt (and RHV respectively) can be installed as: 1. VM in an oVirt Cluster 2. Separate machine(s) In point 2 , the Virt admin should take care about the high availability of the engine. So, you can install CentOS7 and then deploy the engine's software ontop of it. Extracting the OVA will not provide you with fully working engine, as the deployment scripts on the hosts will not inject the necessary data on remote system.

Add Instance_type option for VM Portal

by Vrgotic, Marko

Dear oVIrt, We are relying on Templates more and more, which is great. Images/templates built using “official” cloud images usually have 1CPU and 1GB of RAM. Using this feature via Administration portal is super, since we can attach Instance_type to template to provide sufficient CPU and RAM, regardless of via UI or using Ansible. Would it be possible to consider adding Instance_Type option to Create New VM options in VM Portal? Haven’t tested yet, but is Instance_type supported via ovirt_vm ansible module, in case of EndUser privileges?

iptables with 4.3+?

by Jordan Conway

Hello, I'm working on migrating an existing ovirt setup to a new hosted-engine setup and I've been seeing messages about iptables support being deprecated and slated to be removed. Can I continue using iptables to manage the firewalls on my ovirt hosts if I don't care about allowing ovirt to configure the firewalls? We manage all of our machines with puppet and iptables is deeply integrated into this. It would be non-trivial to migrate to firewalld support. As it stands I already manage the firewall rules for our ovirt hosts with puppet and iptables and have always ignored the "Automatically Configure Firewall" option when adding new hosts. Will this continue to work? Also with hosted engine, I had to cowboy enable firewalld to get the engine installed, but now that I've got a cluster up and running with hosted engine enabled on several hosts, can I just switch back from firewalld to iptables assuming I've got all the correct ports open? Thank you, Jordan Conway

Re: ovirt-engine-appliance ova

by Strahil

Based on my experience - the OVA contains the xml and the actual disk of the hosted engine. Then the deployment starts locally the VM and populates the necessary data in it Once it's over , the deployment shuts down and copies the disk of that local VM, undefines it and then ovirt's ha agents are being configured - so they can mount the shared storage and power up the VM (special tar /OVMF/ file on shared storage has the agent configuration file). So , in the ova there should be a template VM + the xml config (cpus, ram, devices, etc) . I would be surprised if there is something else in it.

hosted engine installation on iscsi multipath/mpath device fails

by Michael Frank

Dear all, since several days i try to install the hosted engine initially to an iscsi multipath device without success. Some information on the environment: - Ovirt Version 4.3.3 - using two 10gbe interfaces as single lacp - bond for the ovirtmgmt interface - using two 10gbe storage interfaces on each hypervisor for iscsi storage -- each storage interface is configured without any lacp bonding or 802.1q tagging, etc (on the switches the vlan is configured; port based vlan) -- each storage interface lives in a serarate vlan were also the iscsi target is available, the iscsi target has 4x10ge interfaces -- so; each storage interface is connected to a iscsi target through a different vlan The documentation here is for me unclear: https://ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_En... <https://ovirt.org/documentation/self-hosted/chap-Deploying_Self-Hosted_En...> >Note: To specify more than one iSCSI target, you must enable multipathing before deploying the self-hosted engine. There is also a Multipath >Helper tool that generates a script to install and configure multipath with different options. This indicates for me that it should be possbile to install the HE directly on the /dev/mapper/mpath device which is availibale when I have prepared the host accordingly before installing the HE (log in to multiple iscsi targets, create proper multipath,conf, etc) - right ? I login to the two iscsi targets and get in sum 8 pathes, 4 from each interface and iscsi target. I have then the mpath device on the hypervisor available and i can mount the mpath device and put (test) data on it. In the cockpit interface the mount can also be activated and is recognized correctly. multipathd -ll and lsblk looks good. Everything seems to be fine. But when I run the "hosted-engine" --deploy, the last option while running the assistant is to enter the iscsi data. So, basically i just want to define my mpath device - when entering the data for one of my iscsi target I can see the 4 pathes of the single target, and when i choose the path where the "lun" is finally available it fails. I think in general this option is not that what i want to have here for using the multipath device. I' m lost - what is the usual way to install the HE on a mutlipath device ? Do I have to change the configuration of the storage interfaces or the iscsi network design? - Are bond interfaces for these iscsi connections mandatory ? Did I missed something obvious ? Can I put in my multipath data into the answerfile somehow to get rid of the last step of the assistant ? Is it not possible in general ?? : https://bugzilla.redhat.com/show_bug.cgi?id=1193961 <https://bugzilla.redhat.com/show_bug.cgi?id=1193961> Sorry in advance for the long mail .... 1!^^ br, michael

Re: System unable to recover after a crash

by Strahil

Hi Carl, I'd recommend you to avoid DNS & DHCP unless you oVirt infra consistes of hundreds of servers. It is far more reliable to use static IPs + /etc/hosts . As you could 'ssh' to the engine, check the logs - there should be a clue why it failed. Most probably it's related to the DNS/IP used. I think the devs can tell their opinion on Monday.

Does Ovirt 4.3.4 have support for NFS 4/4.1/4.2 or pNFS

by Erick Perez

I have read the archives and the most recent discussion was 5 years ago. So I better ask again. My NAS runs Centos with NFS4.2 (and I am testing Ganesha in another server) Does Ovirt 4.3.4 have support for NFS 4/4.1/4.2 or pNFS Specially version 4.2 due to: Server-Side Copy: NFSv4.2 supports copy_file_range() system call, which allows the NFS client to efficiently copy data without wasting network resources. But this will only happen if the Ovirt (which I know is Centos based) supports NFS 4.2. Not sure If I update the NFS toolset on the Ovirt install, it will break something or worst.

"Actual timezone in guest doesn't match configuration" for Windows VMs since guest agent 4.3

by Matthias Leopold

Hi, the oVirt guest agent seems to report DST configuration for the timezone since version 4.3 (of the guest agent). this results in "Actual timezone in guest doesn't match configuration" messages in the UI for windows VMs because the timezone field can't be matched with oVirt configuration anymore (no DST flag). to me this looks like a bug. shall I report it? I know there was a similar thread at the beginning of May, but there was no solution mentioned. Matthias

Update 4.2.8 --> 4.3.5

by Christoph Köhler

Hello! We have a 4.2.8 environment with some managed gluster-volumes as storage domains and we want to go up to 4.3.5. How is that procedure especially with the gluster nodes in ovirt that are running 3.12.15? My fear is on the jump to gluster 6. Do the cluster work if the first node (of three) is upgraded? And what about the sequence - first the hypervisors or first gluster nodes? Is there anyone who had done this? Greetings! Christoph Köhler

Re: VM Migrations Failing

by Strahil

Power down the VM and reduce the memory a little bit but keep the maximum memory value the same or larger. Then power it up and extend the ram to the same value the VM had. It's a wild guess... So don't expect miracles.

Manual Migration not working and Dashboard broken after 4.3.4 update

by Neil

Hi guys. I have two problems since upgrading from 4.2.x to 4.3.4 First issue is I can no longer manually migrate VM's between hosts, I get an error in the ovirt GUI that says "Could not fetch data needed for VM migrate operation" and nothing gets logged either in my engine.log or my vdsm.log Then the other issue is my Dashboard says the following "Error! Could not fetch dashboard data. Please ensure that data warehouse is properly installed and configured."

Re: Impossible to install VM Machine

by Juan Pablo Lorier

Hi Abdoul, what I don't get right is what is your setup. Ovirt can have data domains that is where you put the vm disks. That domains can be NFS share, gluster bricks, iscsi san or direct disk. When you say files sharing folders, I can't think of a data domain attached there unless it's a NFS local share. Maybe I'm missing something, but I can see that working. Do you have a data domain in storage? I tend to think you have because otherway you can't create the disks for the vms (which you add when you create the vm) Please, replay to the list too so others can see the thread.

Re: iptables with 4.3+?

by Strahil

Firewalld was deployed in EL7 , because they got plans of getting rid of iptables. With EL8 , we got only emulation of iptables for backward compatibility. Also the integration between NetworkManager.service and firewalld is quite good - which is another reason behind that. Last but not least, in the enterprise almost all systems are with firewalld down and behind hardware-based appliances and keeping the complex filtering away of the systems. Thus firewalld is nice for simple tasks, while complex tasks require nftables ... It makes sense and we have to deal with the changes or get extended support for as long as possible :) Best Regards, Strahil NikolovOn Jul 10, 2019 18:13, Michael Watters <wattersm(a)watters.ws> wrote: > > Same here.

VM Migrations Failing

by Michael Watters

I need to migrate running VMs from one host in our cluster to another however the task keeps failing any time I start a migration. The engine logs show a few different errors as follows. 2019-07-10 09:53:19,440-04 ERROR [org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer] (ForkJoinPool-1-worker-2) [] Migration of VM 'vm1' to host 'ovirt-node-production3' failed: VM destroyed during the startup. 2019-07-10 09:53:06,542-04 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-51) [c1daf639-ff39-4397-b1bf-09426cacf72d] EVENT_ID: VM_MIGRATION_FAILED(65), Migration failed due to a failed validation: [Cannot migrate VM. There is no host that satisfies current scheduling constraints. See below for details:, The host ovirt-node-production3 did not satisfy internal filter Memory.] (VM: vm2, Source: ovirt-node-production2). I also checked the vdsm.log on the destination host which is showing an error like this. ERROR (jsonrpc/2) [virt.vm] (vmId='f5bb25a8-3176-40b6-b21b-f07ed1089b27') Alias not found for device type balloon during migration at destination host (vm:5562) Does anybody know how to resolve this? The destination host is able to run VMs and I've been able to move a few VMs by shutting down and doing a restart however I'd like to do a live migration if possible.

ovirt_disk and ubuntu issues

Dear oVirt, I am downloading the ubuntu cloud image 16.04 and or 18.04: - name: "Download base cloud image from server" get_url: url: "{{ image_url }}" checksum: "sha256:{{ image_checksum }}" validate_certs: yes dest: "/tmp/{{ inventory_hostname_short }}.qcow2" delegate_to: localhost creating a 40GB HDD and attaching image to it: - name: "Create oVirt disk with base image (with 40Gb allocated)" ovirt_disk: name: "{{ inventory_hostname_short }}" interface: virtio size: 40GiB format: cow upload_image_path: "/tmp/{{ inventory_hostname_short }}.qcow2" storage_domain: ovirt_production wait: true delegate_to: localhost creating VM afterwards: - name: "Create new Ubuntu VMs from cloud image" delegate_to: localhost ovirt_vm: auth: "{{ ovirt_auth }}" name: "{{ inventory_hostname_short }}" disks: - name: "{{ inventory_hostname_short }}" graphical_console: protocol: vnc serial_console: true usb_support: true soundcard_enabled: false operating_system: "{{ operating_system_type }}" type: server nics: - name: nic1 profile_name: tenant1 interface: virtio nic_on_boot: true cloud_init: host_name: "{{ inventory_hostname }}" user_name: ubuntu authorized_ssh_keys: "{{ ssh_agent_pubkeys.stdout }}" state: "running" cluster: "{{ ovirt_cluster }}" when: inventory_hostname in groups['ubuntu-baker'] When VM gets created, I can see in oVIrt VM details disk created is 40GB. Executing df -h, gives me following: root@av3-ubuntu-18-base:/home/ubuntu# df -h Filesystem Size Used Avail Use% Mounted on udev 447M 0 447M 0% /dev tmpfs 92M 696K 92M 1% /run /dev/vda1 2.0G 1.3G 706M 65% / tmpfs 460M 0 460M 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 460M 0 460M 0% /sys/fs/cgroup /dev/vda15 105M 3.6M 101M 4% /boot/efi tmpfs 92M 0 92M 0% /run/user/1000 Initially I thought growpart or resize2fs is not triggered, but then running dmesg or fdisk /dev/vda, told me that physical disk size is still only size of the downloaded ubuntu cloud image.

Re: Help!

Edit the VM and go to 'system' tab (on the left). If you don't see it -click on 'show advanced options'. There select Harddisk as 1st device and DVD as second. Also mark the tick for the disk and from the dropdown choose your install disk. Then poweroff and then poweron.

Impossible to install VM Machine

Good evening Today it's been almost a week since my efforts are in vain in the face of this problem that pushes me to write to you again. I installed ovirt 4.3 on a minimal centos installation. Then I confided ovirt as well as the iso and data domains. Now the problem, I try to create a VM by setting up the entries and attaching a CD from the iso data center. As soon as I run the machine by opening the console, the VM blocks on the boot and the installation does not start. I'll give you two previews for my config and the problem in question.

Ovirt Hyperconverged Cluster

by raffaele＠stefanile.com

I am installing ovirt 4.2 on three nodes. I am using centos with ovirt cockpit. My /sdb is my boot disk and /sda is my local storage, When I started the setup with cockpit I selected the sda but the ansible script stay on sdb. I have fix all changing the playbook manually but in the execution the gdeploy tool stay blocked on TASK [Create Physical Volume] . I don't find any logs. How I can fix that?

Regarding VDSM_Hooks

by Vrgotic, Marko

Dear oVIrt, Happy to report I have deployed my first python vdsm_hook which removes A, AAAA, TXT records of VM each time after_vm_destroy event is triggered, and it works fine. This was required to be able to quickly redploy/rebuild VMs using same hostname. Issue I am observing/just discovered now is: Since live_migration of VM guest is considered a destruction from Host perspective, DNS records get deleted and VM lands on new host without being resolvable 😊 . I would like to introduce another python script for hook regarding migration events to get these entries back into DNS but for that I need there IPs. Question: * Where can I find/locate/read VMs IPs and Hostnames (is it dom_xml) to be able to incorporate them for DNS Update script? If its relevant for the question: we are currently running oVIrt 4.3.3 version Kindly awaiting your reply. Marko Vrgotic ActiveVideo

VM Portal please add search filter box and list view as in Administration portal

by Vrgotic, Marko

Dear oVirt, This email has bounced two times already, and I am not sure what is wrong. Hopefully you get it this time. Request is below. Sent from my iPhone Dear oVirt, Would it be possible to discuss/consider adding search/filter field for VM Portal, resembling one in Administration Portal? I have 60 users with over 500VMs and it would be really good to have this option. At this moment is virtually impossible to use the VMPortal due to poor view options. We are currently running oVirt 4.3.3. — — — Met vriendelijke groet / Kind regards, Marko Vrgotic Sr. System Engineer @ System Administration m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com>

Ethernet tools for VM's

by Mark Steele

oVirt Enginge Version: 3.5.0.1-1.el6 (yes....I know it's old) VM is running Ubuntu 18.04 with ovirt agent installed.

[ANN] oVirt updates

by Sandro Bonazzola

oVirt community, Today marks a new day in the 26-year history of Red Hat. IBM has finalized its acquisition of Red Hat, which will operate as a distinct unit within IBM moving forward. What does this mean for Red Hat’s contributions to the oVirt project? In short, nothing. Red Hat always has and will continue to be a champion for open source and projects like oVirt that have played such a large role in driving innovation in the virtualization space. IBM is committed to Red Hat’s independence and role in open source software communities so that we can continue this work without interruption or changes. Our mission, governance, and objectives remain the same. We will continue to execute the existing project roadmap as we’ve been doing since 2011 for the oVirt project. Red Hat associates will continue to contribute to the upstream in the same way they have been. And, as always, we will continue to help upstream projects be successful and contribute to welcoming new members and maintaining the project. We will do this together, with the community, as we always have. If you have questions or would like to learn more about today’s news, I encourage you to review the materials below. Red Hat CTO Chris Wright will host an online Q&A session in the coming days where you can ask questions you may have about what the acquisition means for Red Hat and our involvement in open source communities. Details will be announced on the Red Hat blog [1]. * Press release [2] * Blog from Chris Wright [3] * FAQ [4] Sandro Bonazzola, Manager, Software Engineering [1] https://www.redhat.com/en/blog [2] https://www.redhat.com/en/about/press-releases/ibm-closes-landmark-acquis...

Managed Block Storage

by dan.poltawski＠tnp.net.uk

I'm testing out the managed storage to connect to ceph and I have a few questions: * Would I be correct in assuming that the hosted engine VM needs connectivity to the storage and not just the underlying hosts themselves? It seems like the cinderlib client runs from the engine? * Does the ceph config and keyring need to replicated onto each hypervisor/host? * I have managed to do one block operation so far (i've created a volume which is visible on the ceph side), but multiple other operations have failed and are 'running' in the engine task list. Is there any way I can increase debugging to see whats happening?

Storage domain format version info

by Gianluca Cecchi

Hello, part of updating a DC from 4.2 to 4.3 consists in updating format of data storage domains from V4 to V5. Questions: - where can I find list of differences between V4 and V5? And in general between previous ones? - can I force only a particular storage domain to remain in V4 while having the other ones upgraded to V5, for any reason? Or the reverse: update only one of the defined domains? Eg on oVirt web site I only found this for V4 https://www.ovirt.org/develop/release-management/features/storage/storage... with mention about Qcow2 v3 (link broken.. one ot the upstream pages for it here: https://wiki.qemu.org/Features/Qcow3 ) that should give near raw performance with advantages of qcow2 format... Thanks, Gianluca

Ovirt Secure boot issues

by Strahil

Hello All, I would like to ask any of you to do a simple test. Please install a linux on a VM with Secure boot and after the install wizzard is over -power it off and then on. Here is what I have observed: 1. UEFI forgets the certificates after a poweroff and asks for the openSUSE certificate every time. Rebooting from the VM doesn't cause any problems till nextg boot. 2. RHEL8 grub menu consists only of 'System setup'. When you select it - you are sent to the UEFI menu. If you select continue - everything is fine. Poweroff + Poweron makes everything to repeat. Do you observe the same issues. If I'm not the only one hitting this - I will open a bug, otherwise I will try to further debug this. Best Regards, Strahil Nikolov

HE deployment failing

by Parth Dhanjal

Hey! I'm trying to deploy a 3 node cluster with gluster storage. After the gluster deployment is completed successfully, the creation of storage domain fails during HE deployment giving the error: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Error: the target storage domain contains only 46.0GiB of available space while a minimum of 61.0GiB is required If you wish to use the current target storage domain by extending it, make sure it contains nothing before adding it."} I have tried to increase the disk size(provided in storage tab) to 90GiB. But the deployment still fails. A 50GiB storage domain is created by default even if some other size is provided. Has anyone faced a similar issue? Regards Parth Dhanjal

Re: UI - cannot remove disk whiel system is running

Re: UI - cannot remove disk whiel system is running

I think I'm getting closer. It seems the snapshot of the VM did not get deleted and that might be the problem. Can someone give me a hint how to remove the snapshot as I get an error: Cannot remove Snapshot. The following disks are in ILLEGAL status: uyuni-OS-Disk1 - please remove them and try again. Yet, removal of the disk cannot happen as I got: Cannot detach Virtual Disk. The disk is already configured in a snapshot. In order to detach it, remove the disk's snapshot. This seems like 'Catch 22' .

UI - cannot remove disk whiel system is running

Hello All, I have changed my system layout and the old disk is removed (echo 1 > /sys/block/sdX/device/delete) from OS, but UI complains when I try to remove with the following error: Error while executing action: Cannot remove Virtual Disk. At least one of the VMs is not down. Is it a limitation of oVirt ? If so, I will open an enhancement entry in bugzilla. As far as I remember KVM allowed me to make such stuff without any issues so far. Best Regards, Strahil Nikolov

VM snapshot - some info needed

by Strahil Nikolov

Hello Community, I have noticed that if I want a VM snapshot with memory - I get a warning "The VM will be paused while saving the memory" .Is there a way to make snapshot without pausing the VM for the whole duration ? I have noticed that it doesn't matter if VM has qemu-guest-agent or ovirt-guest-agent. Thanks in advance for sharing your thoughts. Best Regards,Strahil Nikolov

Experience 4.1.x -> 4.2.8 -> 4.3.4 upgrade lessons

by Richard Chan

Hi oVirters, Did a 4.1 - > 4.2.8 -> 4.3.4 upgrade in two hops. Here is my experience, hope it can save you some pain. Gotchas 1. For shutdown VMs, their disks were deactivated (though still attached) 2. For shutdown VMs, their NICs were "Up" but "Unplugged" 3. VM Custom Compatibility Version is hard to find. (If it is too old say 3.6, 4.1) they won't start up. The location is: VM -> Edit -> System -> Advanced Parameters (click this) "Advanced Parameters" is an expandable widget that is quite small when collapsed. When it is expanded then you will see "Custom Compatibility Version" 4. Storage Domain migration to V5: I use a NFS storoage domain. This is migrated to the "V5" format and a lot of cleanup is done. If you have stray files or images not owned by 36:36 (vdsm:kvm on my NFS server), the V5 upgrade will fail, there will be no SPM, and the Data Center will oscillate between Non-responsive and Contending. Why would there be non 36:36 uid/gid files? This is a long story, but from the older 3.x days when there was less functionality, we would sometimes directly manipulate the filesystem and/or qcow2 images using guestfish or equivalent tools which would change the owner to qemu:qemu. Forgetting to chown back to vdsm:kvm is a recipe for pain. Cheers! -- Richard Chan

Anaconda crashing on start while trying to Install oVirt Node on bare metal

by rubentrindade＠live.com

Hello there! I'm trying to install an oVirt node(the most stable recent one) on a machine(just in case you didn't figure from the title :P) and anaconda just crashes \o/ I've tried to start anaconda in text mode, but the error is the exact same. Here's a screenshot of the event(text mode, although it shouldn't matter): https://i.imgur.com/ihO1xWP.jpg The only "disk" attached to the machine has no partitions, it's absolutely clean. The machine in question is a PowerEdge M520, if that matters, and I'm trying to install on top of a pair of 32GB mirrored SD cards. I installed CentOS7 on a machine that's virtually the same(they're the exact same, but aren't the same machine) and didn't have any problem. I just have no idea. Never encountered such problem. So any help would be very appreciated. Thanks ^^

Re: [ovirt-devel] USB on host support?

by Juan Pablo Lorier

I'm having a similar problem. The passtrough needs 2 steps, the first is to attach the host device to the VM, but if you don't enable the spice usb the vm fails to start. I don't know if the USB works straight from the host device or if it depends on the spice console. In my case, a device that work in a windows 10 pc doesn't work in a windows 10 vm. Maybe we both can get help in this matter.

4.3 won't upgrade engine in standalone KVM VM: low_custom_compatibility_version 'agent03'

by Richard Chan

Hi, I am running 4.2 engine in a standalone libvirt KVM VM (running on a hypervisor that is not part of the oVirt infrastructure); i.e., I am not using hosted engine but still running engine in a VM. Now 4.3 won't upgrade inside this libvirt KVM VM: Failed to execute stage 'Setup validation': Cannot upgrade the Engine due to low custom_compatibility_version for virtual machines: ['agent03']. Please edit this virtual machines, in edit VM dialog go to System->Advanced Parameters -> Custom Compatibility Version and either reset to empty (cluster default) or set a value supported by the new installation: 4.1, 4.2, 4.3. engine-setup has probably detected that it is running inside a VM: 1. Where did it get 'agent03' string from 2.

Bad Gateway buhaa

by Vrgotic, Marko

Dear oVIrt, Although it should be simple, I am failing to understand the connection between Default Gateway setting and Bad Gateway issue. On which network I need to set default gateway: Our ovirtmgmt is set not to be used by Guest VMs, only Hosted-Engine. We have tenant1 network which is assigned to VM Guest instances and it has Default Gateway, working one 😊. Why am I still seeing this message: 2019-07-04 12:53:08,991Z ERROR [org.ovirt.engine.core.bll.provider.network.SyncNetworkProviderCommand] (EE-ManagedThreadFactory-engineScheduled-Thread-54) [2cfff521] Command 'org.ovirt.engine.core.bll.provider.network.SyncNetworkProviderCommand' failed: EngineException: (Failed with error Bad Gateway and code 5050) What am I doing wrong? If you need more info or log data, just let me know. oVIrt 4.3.3 Kindly awating your reply. Marko Vrgotic ActiveVideo

Re: Anaconda crashing on start while trying to Install oVirt Node on bare metal

by Strahil

If you don't have a raid controller with battery-backed cache - disable the raid in bios. Fake raids are just like software raid, use the cpu for calculations and could be a potential problem if the Motherboard dies. Software raid (controlled by mdadm) and lvm raid (sane driver but controlled from lvm) can easily be recovered on any type of linux (as long as it is not too old ofc) and do not have the minuses of the fake raid.

Re: lvm agregation of lun in a storage domain

I think the simplest way is to get a new LUN and migrate the VM disks to it. Once the 2 old LUNs are free - you can release them both.

Issue adding Network to host with Python SDK

by Don Dupuis

I am having issue with adding network to host nic with python SDK. It works just fine using the portal GUI. I have the following: bond0 that is setup as mode 4 bond0.120 that is attached to ovirtmgmt network bond0.96 that I am trying to attach a new installed network called External.

Spice console very poor performance for Windows 10 vm

by Leo David

Hello Everyone, Maybe I am something wrong, but spice console seem to be very laggy and slow for windows 10 vms. I have tried both qxl and qxl-dod drivers, but no luck so far... As a notice, the Win 2012R2 vm console is running fine, the problem seems to only affect Windows 10. Any ideas, what should I do to sort this out ? Thank you very much !

Re: Hosted Engine Deploy - Error at the end... [NFS ?]

Have you checked if the permissions are 36:36 on the NFS side ?

Using a synology as an nfs storage

by Andy Michielsen

Hello, I'm setting up a 3 node cluster with the ovirtnode iso and a seperate server with the engine on and a synology for nfs storage. I have done my configuration and I'm able to mount the share manually on the node with a command. Also on the server with the engine on I can mount it manually. But when I want to do it through the webinterface to add a data domain it say the permissions are wrong. Any idea's on how to figure this out ? Kind regards.

Hosted Engine Deploy - Error at the end... [NFS ?]

by csi-laser＠cisco.com

Hi, While Trying to Deploy Hosted Engine, I'm stuck on Stage 4. Here is the error : [ INFO ] TASK [ovirt.hosted_engine_setup : Fetch Datacenter name] [ INFO ] ok: [localhost] [ INFO ] TASK [ovirt.hosted_engine_setup : Add NFS storage domain] [ ERROR ] Verify permission settings on the specified storage path.]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Permission settings on the specified path do not allow access to the storage.\nVerify permission settings on the specified storage path.]\". HTTP response code is 400."} But, it's very strange, because, when I'm trying to mount this NFS share manually, It's working.... So what am I doing wrong here ? Here is the "Storage Connection" - 8.45.119.16:/ovirt_engine Mount option is blanked NFS Version is "v3" Thanks in advance !

network performance issues

by Guy Brodny

Hello. we have installed Ovirt on HPE ProLiant XL270d Gen10. The server is installed with 2 * Intel(R) Xeon(R) Gold 6154 CPU @ 3.00GHz, 1.5T Ram, 23T Local SSD, 4 Nvidia V100 32GB GPU and 2* Mellanox Technologies MT27800 Family [ConnectX-5] The Mellanox card are 2 100Gbit DualPort each connected with a single 100Gbit port to a Mellanox 100Gbit switch which has access to a 16GByte storage server. MTU is set to 9000 for jumbo packets. Running our application on a VM created on top of the server is having lower network performance vs the host. I tried both normal ovirt network driver, using Virtual Function and PCI-passthrough moving one of the Mellanox card directly to the VM but i never get the same result as on the host. I also tried allocating the numa bush directly to the VM but it doesnt improve the results. Im testing using FIO to perform sequential reads from the storage, this is the command we run both on the host and the VM. sqream@host-3-171 /media/StorONE1/tpch10t_for_4.0/logs/192.168.3.171_5000 $ fio --randrepeat=1 --ioengine=sync --direct=1 --gtod_reduce=1 --name=test --filename=/media/StorONE3/t1e1s1111t221www22.file --bs=2m --iodepth=24 --size=25G --numjobs=14 --readwrite=read --rwmixread=100 Run status group 0 (all jobs): READ: bw=3919MiB/s (4109MB/s), 280MiB/s-314MiB/s (294MB/s-329MB/s), io=350GiB (376GB), run=81630-91459msec Before starting Ovirt i measured 7.5GB/sec on the host running the same FIO command. are there any optimization i should perform to make sure the vguest i getting the best possible network performance, im mostly stressed about GPFS performance as this is our main filesystem. On the same time running the test on another host not running Ovirt i can still get the 7.9GB/sec. appreciate any comments or suggestions.

oVirt node 4.3.4 stable can't deploy hosted engine to iscsi target all available LUNs used

by Mitja Pirih

Hi, I am new to oVirt, coming from XenServer platform, so please be patient with me. After a successful install of latest stable oVirt node (ovirt-node-ng-installer-4.3.4-2019061016.el7.iso) I am having troubles deploying hosted engine to an iscsi target over Cockpit. I have a couple of iscsi targets available on two different storage platforms (Synology DS418, Lenovo DE2000H). After retrieving iscsi Target list all LUNs get automatically "connected" by "Target list scan" and shown as used on LUNs list. I can reproduce this every single time. On storage system I can also see, that all LUNs get connected by the initial scan. As a result I an unable to continue the deployment as there are no LUNs available. Is this a normal behavior? What would you suggest me to do? Thanks.

Adding a custom fence agent on 4.3.4

by Matteo

Hi, I'm trying to add a custom fence agent for my test deployment on hetzner. Have written a small fence_hetzner_robot script which works ok from cli and installed on every ovirt node. Then added with engine_config in this way: # engine-config -s CustomVdsFenceType="hetzner_robot" But does not show up in fence agents list under host pm configuration. I'm missing something? thanks! Matteo PS: Also tried to set up an empty param mapping, just to test # engine-config -s CustomVdsFenceOptionMapping="hetzner_robot:" but still nothing.

SPICE and VNC native

by kim.kargaard＠noroff.no

Hi, We are running ovirt 4.3. The engine is on a bare metal machine and the hosts are running on Centos 7. When installing the engine, I set it to be the webproxy. When I create a new vm, I select both SPICE+VNC. When clicking on the console I only have the option for SPICE native, not for the HTML option. For VNC I have both options and the HTML option can be selected and works. But, this is also the only option that works. VNC Native as well as SPICE Native do not work. I have tried using both remote viewer on Mac and a VNC client on a Windows machine and neither will actually open the VM. I would really also like the SPICE HTML option to exist, but it does not. The enable SPICE proxy in the Console selection is greyed out. When I open in remoteviewer (Mac) I get Unable to connect to the graphic server. Any suggestions? Kim

it seems vgpu state be mistack freed when operating(start and stop) vm at the same time

by weizhengya16＠gmail.com

We using ovirt in production environment with each virtual machine with a vGpu。but serveral days later, I find several phisical server has been crash and automatic reboot。And I also found some vGpu exist with no virtual machine using. So it makes virtual machine start fail because of lacking resource.I must enter the vgpu directory and using "echo "1" >remove" to free this vGpu。With ceaselessly stop and start, the probability of its occurrence is approximately 0.1%-1%

[ANN] Incubating terraform-provider-ovirt

by Roy Golan

Hi all, Happy to announce the incubation of a terraform provider[1] for oVirt which is the the result of a community effort started by ESM-MSC institute [2] and then picked up by @imjoey [3] which is now the main maintainer of the project. Terraform with an ovirt provider makes it easy to declaratively create virtualized environments. One usage we will make of it is to create an installer for OKD 4 [4] which will lay an OKD cluster on top of oVirt resources.

There were various lease errors for the servers but they came up and seemed functional. Clearly the issue is here: "Exception in startFailedAutoStartVms" in the "START_ARRAY token" but I can't find anything as of yet that says if you see this - do x,y,z. Learning oVirt so my apologies if this is a 101 question.

Re: SPICE and VNC native

by Strahil

The graphics server is the actual host. Can you directly access SPICE/VNC port from your workstation? Best Regards, Strahil NikolovOn Jul 1, 2019 13:31, kim.kargaard(a)noroff.no wrote: > > Hi, > > We are running ovirt 4.3. The engine is on a bare metal machine and the hosts are running on Centos 7. When installing the engine, I set it to be the webproxy. When I create a new vm, I select both SPICE+VNC. When clicking on the console I only have the option for SPICE native, not for the HTML option. For VNC I have both options and the HTML option can be selected and works. But, this is also the only option that works. VNC Native as well as SPICE Native do not work. I have tried using both remote viewer on Mac and a VNC client on a Windows machine and neither will actually open the VM. I would really also like the SPICE HTML option to exist, but it does not. The enable SPICE proxy in the Console selection is greyed out. > > When I open in remoteviewer (Mac) I get Unable to connect to the graphic server. > > Any suggestions? > > Kim > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/site/privacy-policy/ > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/PDH2UJKZC2X...

Re: USB Passtrough device problem

by Strahil

You can attach the usb to an oVirt node and check the module in use there. Then you can try patthrough the device and check the module in use on the VM (if it's linux) or install the driver (if Windows).

Re: Mix CPU

No. Keep the hosts with different Brand CPU in separate clusters. For example, I have 2 gluster Bricks with AMD (default cluster) and an Intel-based arbiter (Intel cluster).
