vdsm+engine logs

Description of problem:

Force remove storage domain(aka destroy) from a DC with 2 or more storage domain
can cause disappearance of the vm from a DC without any pop-up warning or error on logs, or in the case of vm that is in status: "up", it becomes external, all the disks he had becomes floating disks and all attempts to add or attach them back is block by CanDoAction:
"Cannot add Virtual Machine Disk. This VM is not managed by the engine"
the result is the loss of what can be a vital data since all Virtual Machine Memory is deleted,or cannot be accessed. 


Version-Release number of selected component (if applicable):
av9.5
vdsm-4.14.7-3.el6ev.x86_64
