    Description

      In some conditions (race condition), VR gets rebooted after a out of band migration was done on vCenter.

      Note, new global setting in 4.5.2 "VR reboot after out of band migration" is set to false and this looks more like a bug.

      After a VR migration to a host and when the VM power state report gathering is running, the VR (and also any user VM as well) will get into the "PowerReportMissing".

      If the VM is a VR. it will be powered off and started again on vCenter. That is what we see. In can not be reproduced every time a migration was done, but it seems the problem is related to "powerReportMissing".

      I grep-ed the source and found this line related

      https://github.com/apache/cloudstack/blob/4.5.2/engine/orchestration/src/com/cloud/vm/VirtualMachineManagerImpl.java#L3616

      and also it seems that the graceful period might be also related,

      https://github.com/apache/cloudstack/blob/4.5.2/engine/orchestration/src/com/cloud/vm/VirtualMachinePowerStateSyncImpl.java#L110

      In case it is a user VM, we see in the logs that the state will be set to powered-off, but the VM keeps running. After a while a new VM power state report is running and the state for the user VM gets updated to Running again. Below the logs

      VR r-342-VM reboot log
