Hello,
=20
last Wednesday I wanted to update my oVirt 3.5 hypervisor. It is a =
single Centos 7 server, so I started by suspending the VMs in order to =
set the oVirt engine host to maintenance mode. During the process of =
suspending the VMs the server crashed, kernel panic=E2=80=A6
After restarting the server I installed the updates via yum an restarted =
the server again. Afterwards, all the VMs could be started again. Some =
hours later my monitoring system registered some unresponsive hosts, I =
had a look in the oVirt interface, 3 of the VMs were in the state =
=E2=80=9Cnot responding=E2=80=9D, marked by a question mark.=20
I tried to shut down the VMs, but oVirt wasn=E2=80=99t able to do so. I =
tried to reset the status in the database with the sql statement
=20
update vm_dynamic set status =3D 0 where vm_guid =3D (select vm_guid =
from vm_static where vm_name =3D 'MYVMNAME');
=20
but that didn=E2=80=99t help, either. Only rebooting the whole =
hypervisor helped=E2=80=A6 afterwards everything worked again. But only =
for a few hours, then one of the VMs entered the =E2=80=9Cnot =
responding=E2=80=9D state again=E2=80=A6 again only a reboot helped. =
Yesterday it happened again:

Does anybody know what I can do? Where should I have a look? Hints are =
greatly appreciated!
