Also since the automated test coverage of this area is less, changes should
be made after taking into account all possible scenarios. Otherwise there might
be regressions in some valid scenarios.

> If you loose the communication between the management server and one of the
> agent for a few minutes, even though HA mode is not active the
> HighAvailibilityManager kicks in and start to schedule vm restart. Those
> tasks are being inserted as async job in the DB and if the agent comes back
> online during the time the jobs are still in the async table, they are pushed
> to the agent and shuts down the VMs. Then since HA is not active, the VM are
> not restarted.
> The expected behavior in my opinion is that the VM should not be restarted at
> all if HA mode is not active on them, and let the agent update the VM state
> with the power report.
> The bug lies in
> {{HighAvailibilityManagerImpl.scheduleRestartForVmsOnHost(final HostVO host,
> boolean investigate)}}, PR will follow.
