Hi Andrej,
I missed to point a fact that is probably determining. Prior to noticing
the error, we upgraded the Cluster & Data Center compatibility version
from 4.1 to 4.3, which caused ovirt-engine to automatically edit all VMs
and modify their compatibility versions as well (with changes pending
until next reboot).
So if we powered down the VM, edited the VM, saved it (even without
changes) and powered it up, migrations would work again.
This happened with all affected machines.
If you need some additional info, just ask.
Thanks.

Hi,
The NPE is because the CPU load of a VM is missing. It happens when
the VM statistics are not updated.
This is definitely a bug, missing CPU load should not prevent
migration.
I will open a Bugzilla ticket.
Can you share some more details about the VMs?
Does the NPE happen for all VMs or only some specific types?
Thanks,
Andrej

Hi,
We're running oVirt 4.3.2. When we click on the "Migrate" button
over a
VM, an error popup shows up and in the ovirt-engine log we see:
2019-04-03 12:37:40,897+01 ERROR
[org.ovirt.engine.core.bll.GetValidHostsForVmsQuery] (default
task-6)
[478381f0-18e3-4c96-bcb5-aafd116d7b7a] Query
'GetValidHostsForVmsQuery'
failed: null
I'm attaching the full NPE.
Could someone point out what could be the reason for the NPE?
Thanks._______________________________________________
