Hi,
Let’s say that backup of ovirt engine is done once every day, for example 6 AM
using engine-backup tool.
Then during the day the changes are made that not only influence the database,
but actually influence Libvirt/KVM/QEMU
(create/delete VMs,snapshots, disks, ).
Now let’s say at 18:00 an eng

Not a direct answer – but I think something to consider:

Before doing that you need to understand following:

about iLO/IPMI in oVirt).
There was a loss of communication with the Storage for approximately 3 minutes
and this caused all Hosts to reboot.

Hi,
It looks that ovirt doesn't consider that your host has any PFs/VFs.
You should navigate to ovengine 4.3 and 4.4 and see those differences in 'Host
Devices' in some host.
The basic check is then to check if iommu is 'on' on those hosts. This might
rely on ovengine's control on that (check 'h

The problem/problems don't seem to be related to HE storage in any way.

You need to check whether you use VNC or Spice and check certificates on ovirt

/etc/pki/vdsm/libvirt-vnc/server-cert.pem

and is not expired.

Do I understand it correctly that:

there is no ovirt 4.7, the latest (and it could be the last ☹) version of ovirt
