[ovirt-users] rebooting hypervisors from time to time

Fri Feb 23 17:15:55 UTC 2018

Hi,

The log does't indicate HV reboot, and i see lots of errors in the logs.
During the reboot, what happened to the VM inside of the HV ? migrated ? paused ? what about the system's logs ? does it indicate a graceful shutdown ?

Thanks for the reply,

I've attached all the logs from yesterday, reboot has happened during the day but this is not the first time and this is not the only one hypervisor.

Kind Regards

Erekle

Dear all,

It would be great if someone will share any experience regarding the
similar case, would be great to have a hint where to start investigation.

Thanks again

Cheers
