> Xenserver - After HA , ssvm fails to start on the new host . Also not able to deploy new Vms in this host.
> Steps to reproduce the problem:
> Set up - Advanced zone with 2 hots (Xenserver 6.2) , host1 and host2.
> All user Vms (~11) and system Vms were running on host1.
> power down host1.
> All the HA enabled user Vms and system Vms were able to successfully start on host2 and are reported as "Running" except for SSVM.
> As part of HA process , seems like there were 2 threads that were trying to work on the SSVM ( one trying to stop Vm and other trying to start Vm).
> SSVM fails to start. I see that ssvm getting destroyed and trying to get recreated over and over again with no success.
> Following exception seen in management server logs:
> com.cloud.utils.exception.CloudRuntimeException: We cannot proceed with stop VM VM[SecondaryStorageVm|s-52-VM] since it is not in 'Stopping' state, current state: Stop
