Hi,
Installed and reinstalled, VM HA just does not work for me.
In addition, if the HV going AWOL is hosting the systemvms, then they also do
not get restarted despite available HVs online.
I've opened another ticket with logs:
https://issues.apache.org/jira/browse/CLOUDSTACK-
eboot. Also, it allows HA to kick-in and handle
correctly.

(we have 2 threads interleaving on the libvirt lockd..) - so, did you
manage to understand what can cause the Agent Disconnect in most cases, for

.

I plan on submitting our updates via a pull request at some point. But I can
also send the updated code to anyone that wants to do some testing before then.

Hi Paul,
Thanks for checking. My compute offering is HA enabled, of course.
Host HA is disabled as well as OOBM.
I'll do the tests again on Monday and report back.
