------------------------------------------------

             Summary: Some VMs are being stopped when agent is reconnecting
                 Key: CLOUDSTACK-9458
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9458
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
            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.
