Hello,
All 4 VMs on one of my oVirt cluster node shutdown for an unknown reason
almost simultaneously.
Please help me to find the root cause.
Thanks.
Please note the host seems doing fine and never crash or hangs and I can
migrate VMs back to it later.
Here is the exact timeline of all the related events combined from the host
and the VM(s):
