It comes handy for management application to be able to have a
per-device label so that it can uniquely identify devices it
cares about. The advantage of this approach is that we don't have
to generate aliases at define time (non trivial amount of work
and problems). The only thing we do is parse the user supplied
tag and format it back. For instance:
<disk type='block' device='disk'>
<driver name='qemu' type='raw'/>
<source dev='/dev/HostVG/QEMUGuest1'/>
<target dev='hda' bus='ide'/>
<alias user='myDisk0'/>
I really do not like this - having two arbitrary string alias names is
just crazy. If we want to add a second attribute to uniquely identify
devices, then it should be a UUID IMHO, so it at least has some tangible
benefit instead of just duplicating the existing id format
