deactivated is like having a disk in offline, or hot unplugging when
you still want to retain it in the context of the vm configuration
I understand that, I just argue it's quite useless (offline can be done
from within the guest OS), does not work that way in physical hardware
(offline is a logical action within the OS), has very little value to
the RHEV Admin (unless he's paranoid and afraid that the disk will
become float and someone else would 'steal' it from his VM) and is
annoying to require multiple actions.
