we need to add a message that will be displayed in case that there will be
attempt to acquire exclusive lock

Line 97: return
failCanDoAction(VdcBllMessages.ACTION_TYPE_FAILED_DISKS_LOCKED);
the image can also be illegal for example, can you change the message?

this is unneeded - please remove it, otherwise we need to put it all over the
code

all of those db operations should be done in the same transaction - otherwise
in case of engine crash for example, the image will remain locked.

perhaps remove the for loop from here.
