Change subject: core: fix removal of attached disks to stateless vm
......................................................................


Patch Set 3:

Don't we want the user to unplug those disks instead doing that automatically, 
since he is the one which attach them at the first place?

Please use Entities.getIds(...)

Line 82:                                 getVmId(), activeDiskSnapshot.getId(), 
false, false));
I assume that we want that when a failure occurs the disks which were already 
detached will not be attached again (rollback)?
Do we have any compensation here?
Line 83: 
Line 84:                 if (!returnValue.getSucceeded()) {
Line 85:                     return false;
Line 86:                 }


Line 81:                         new AttachDetachVmDiskParameters(
Line 82:                                 getVmId(), activeDiskSnapshot.getId(), 
false, false));

Line 84:                 if (!returnValue.getSucceeded()) {
Line 85:                     return false;
I think we don't have an audit log indicating that we failed to detach a Disk 
from a VM?
we should indicate this somehow, otherwise the user will not know which disk 
sabotage his attempts of stopping the VM.

Please also add a log here indicating the disk id which failed the detach and 
stopped the process
