> Reporter: Marc-Aurèle Brothier
>
> 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.
