[ovirt-users] Can't start VM after shutdown

[gregor]

Hi,

a VM has snapshots which are unable to remove during when the VM is up.
Therefore I power down the Windows Server 2012 VM. The snapshots are
still unable to remove and the VM can't boot anymore !!!

This is the message from engine.log

------------------
Message: VM srv03 is down with error. Exit message: Bad volume specification
------------------

Clone is not possible I get:
------------------
Message: VDSM command failed: Image is not a legal chain
------------------

All others VM's can be powered down and start without any problem.
What can I do?
This is very important because now no one can work :-( !!!

cheers
gregor
