> Steps:
> 1. Configure Adv Zone with VMWARE ESXI 5.0 using Zone wide primary storage
> 2. Deploy a VM using user account
> 3. Move Zone wide primary storage into maintenance. With this System Vm's
> got migrated to a xenserver host which is one more cluster in the setup.
> 4. Now tried to create ROOT volume snapshot of VMWARE user VM
> 5. It failed saying "Failed to create snapshot due to an internal error
> creating snapshot for volume 194"
> But when looked at snapshot table. There is an entry created for this
> snapshot which is allowcated state. There is no snapshot in the Secondary
> storage. Issue is only about the entry in DB . This is getting displayed with
> listSnapshots from UI.
> Expected results : When there is a failure to create snapshot , we should
> cleanup the entries created for that in the DB.
