At this point, yes, you should use the testing repos, since libivrt and qemu
are too old in CentOS 8.1.

Once CentOS 8.2 is released, we should be good with the official packages.

[ovirt-users] Re: Problem with oVirt 4.4

2020-06-15 Thread Marco Fais
Hi Nir,

I have raised the same issue here:
https://bugzilla.redhat.com/show_bug.cgi?id=1840414

It is indeed working with the libvirt and qemu versions you mention below,
however in order to use them I had to add the testing repository for AV
which could bring other issues...
Also ovirt-node-4.4.0 ships with libvirt 5.6/qemu 4.1 -- if the recommended
versions are the more recent ones, should they not be included in
ovirt-node-4.4.x as well?

Thanks,
Marco

This is a known issue in libvirt 5.6/qemu 4.1.

It works in libivrt >= 6.0 and qemu >= 4.2, which are the versions
needed for 4.4.

I did get them, but not engine logs. Can you please attach them as well? Thanks.

Illegal means that you cannot restore this snapshot, it was modified by merging
data from the next layer, so it does not represent the state of the VM
at the time
of the snapshot any more.

Failure to remove a snapshot should be recoverable by retrying the operation.

If retrying still fails, you should be able to delete the snapshot
after stopping the VM.

If this also fails, there may be an issue in the volume metadata that
needs to be
fixed manually.

Please file a bug if this is the case.

Can you please share relevant parts of engine and vdsm logs? Perhaps
open a bug and attach all of them, just in case.

Hi,

I guess you are hitting the same bug I have reported here:

https://lists.ovirt.org/archives/list/users@ovirt.org/message/AMVU2RS5RHY4OPUFRDEU4F3OEWKDUZXB/


In fact I am hitting it when testing some infrastructure backup solutions
(not only yours) for our oVirt environments...
I have no solution yet and the recommendation is to test with libvirt 6,
but don't think it can apply for oVirt 4.4...

Regards,
Marco
