Side note: on an important VM, if you find yourself in this situation (two 
drives pointing at the same underlying data) and don't want to lose data, 
it's best to stop it as soon as possible.  Probably an xm destroy is better 
than a clean shutdown in this case!

(side note: unless you really have a clear idea of what you're doing and why 
it's safe or it's just a testing VM you can afford to hose)

Sorry to butt in on this, I just have a thing about pepperring the ML archives 
with warnings about this, having once (years ago) hosed a Xen machine 3 times 
in an afternoon doing stuff like this :-)
