[ovirt-users] oVirt 4.0.3 (Hosted Engine) - High Availability VM not restart after auto-fencing of host.

Thu Sep 15 07:27:15 EDT 2016

Hi,

I found out this in the log:

2016-09-15 12:02:04,661 INFO
[org.ovirt.engine.core.vdsbroker.monitoring.VmAnalyzer]
(ForkJoinPool-1-worker-6) [] VM
'660bafca-e9c3-4191-99b4-295ff8553488'(KOM-AD01-PBX02) moved from 'Up' -->
'Down'
2016-09-15 12:02:04,788 INFO
[org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector]
(ForkJoinPool-1-worker-6) [] Correlation ID: null, Call Stack: null, Custom
Event ID: -1, Message: VM KOM-AD01-PBX02 is down. Exit message: User shut
down from within the guest

If I'm not mistaken, this means that VM was properly shutted down from
within itself and in that case it's not restarted automatically. So I'm
curious what actions have you made to make host KOM-AD01-VM31
non-responsive?

If you want to test fencing properly, then I suggest you to either block
connection between host and engine on host side and forcibly stop ovirtmgmt
network interface on host and watch fencing is applied.
