How to connect to a guest with vGPU ?
by Josep Manel Andrés Moscardó 29 May '20

29 May '20

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

Ubuntu 18.04 and 16.04 cloud images hang at boot up
by suaro＠live.com 07 May '20

07 May '20

I'm using oVirt 4.3 (latest ) and able to successfully provision Centos VMs without any problems. When I attempt to provision Ubuntu VMs, they hang at startup. The console shows : ... ... [ 4.010016] Btrfs loaded [ 101.268594] random: nonblocking pool is initialized It stays like this indefinitely. Again, I have no problems with Centos images, but need Ubuntu Any tips greatly appreciated.

ovirt-guest-agent for CentOS 8
by Eduardo Mayoral 30 Mar '20

30 Mar '20

Hi, Just like many of you I am testing my first CentOS 8 VMs on top of ovirt. I am not finding the package ovirt-guest-agent.noarch . Closest I can find is qemu-guest-agent.x86_64 After installing and starting it, I do see information reported on the "Guest info" tab. Can anybody confirm if this is indeed the agent we should be using? Is there - or will there be - a more specific package for ovirt guests? Thanks! -- Eduardo Mayoral Jimeno Systems engineer, platform department. Arsys Internet. emayoral(a)arsys.es - +34 941 620 105 - ext 2153

Re: Hyperconverged setup questions

Hi Marko, I guess you can use distributed-replicated volumes and oVirt cluster with host triplets.

Re: Damaged hard disk in volume replica gluster
by Strahil 25 Feb '20

25 Feb '20

As you are replacing an old brick, you have to recreate the old LV and mount it on the same location. Then you can use the gluster's "reset-brick" (i thing ovirt UI has that option too) and all data will be replicated there. You got also the "replace-brick" option if you decided to change the mount location. P.S.: with replica volumes your volume should be still working, in case it has stopped - you have to investigate before proceeding.

terraform integration

Hello, I'm interested by installing okd on ovirt with the official openshift installer (https://github.com/openshift/installer) but ovirt is not yet supported. Regarding https://bugzilla.redhat.com/show_bug.cgi?id=1578255 and https://lists.ovirt.org/archives/list/users@ovirt.org/thread/EF7OQUVTY53GV3… , how ovirt 4.3.7 should integrate openshift installer integration with terraform? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Unsynced entries do not self-heal during upgrade from oVirt 4.2 -> 4.3
by Goorkate, B.J. 20 Feb '20

20 Feb '20

Hi all, I'm in the process of upgrading oVirt-nodes from 4.2 to 4.3. After upgrading the first of 3 oVirt/gluster nodes, there are between 600-1200 unsynced entries for a week now on 1 upgraded node and one not-yet-upgraded node. The third node (also not-yet-upgraded) says it's OK (no unsynced entries). The cluster doesn't seem to be very busy, but somehow self-heal doesn't complete. Is this because of different gluster versions across the nodes and will it resolve as soon as I upgraded all nodes? Since it's our production cluster, I don't want to take any risk... Does anybody recognise this problem? Of course I can provide more information if necessary. Any hints on troubleshooting the unsynced entries are more than welcome! Thanks in advance!

Vm suddenly paused with error "vm has paused due to unknown storage error"
by Jasper Siero 18 Feb '20

18 Feb '20

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.

Re: Cannot Increase Hosted Engine VM Memory
by Serhiy Morhun 13 Feb '20

13 Feb '20

Hello, did anyone find a resolution for this issue? I'm having exactly the same problem: Hosted Engine VM is running with 5344MB of RAM, when trying to increase to 8192 it would not accept the change because the difference is not divisible by 256. When trying to increase to 8160 the change is accepted but log shows "Hotset memory: changed the amount of memory on VM HostedEngine from 5344 to 5344" at the same time amount of guaranteed memory does increase to 8160 which, in turn, starts generating error messages that VM does not have all the guaranteed RAM.
