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.

Ubuntu 18.04 and 16.04 cloud images hang at boot up
by suaro＠live.com
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
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!

Re: Hyperconverged setup questions
by Strahil
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
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.

Unsynced entries do not self-heal during upgrade from oVirt 4.2 -> 4.3
by Goorkate, B.J.
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!
Regards,
Bertjan

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.

CentOS Linux release 7.1.1503

*So, what gives? I already disabled all ssh security in the physical host,
and whitelisted all potential IPs from the engine using firewalld.
Regardless, the engine can ssh to the host as root :-(. Is there maybe
another user that's used for the "Wait for the host to be up" SSH test?
Yes, I tried both passwords and certificates.*
*Maybe what's really happening is that engine is not getting the right IP?
bric-ovirt-engine is supposed to get 10.130.0.50, instead it never gets
there, getting 192.168.1.52 from virbr0 in bric-ovirt-1. See below.*

Re: Cannot Increase Hosted Engine VM Memory
by Serhiy Morhun
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.
