Error exporting into ova
by Gianluca Cecchi
Hello,
I'm playing with export_vm_as_ova.py downloaded from the examples github:
https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/export...
My environment is oVirt 4.3.3.7 with iSCSI storage domain.
It fails leaving an ova.tmp file
In webadmin gui:
Starting to export Vm enginecopy1 as a Virtual Appliance

During export I have this qemu-img process creating the disk over the loop

The ova.tmp file is getting filled while command runs

It seems 30 minutes... for timeout? About what, ansible job?
Or possibly implicit user session created when running the python script?
The snapshot has been correctly deleted (as I see also in engine.log), I
don't see it in webadmin gui.
Any known problem?
Just for test I executed again at 14:24 and I see same Ansible error at
14:54
The snapshot gets deleted, while the qemu-img command still continues....

and then continues until image copy completes, but at this time the job has
already aborted and so the completion of the ova composition doesn't go
ahead... and I remain with the ova.tmp file...
How to extend timeout?

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!

Re: Single instance scaleup.
by Strahil
Hi Leo,
As you do not have a distributed volume , you can easily switch to replica 2 arbiter 1 or replica 3 volumes.
You can use the following for adding the bricks:

Failed to add storage domain

Hi!
I have installed oVirt using the iso ovirt-node-ng-installer-4.3.2-2019031908.el7. I the did run the Host-engine deployment through Cockpit.
I got an error when it tries to create the domain storage. It sucessfully mounted the NFS-share on the host. Bellow is the error I got:

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.
