Just to clarify, by 'everything works perfectly' I mean that a domain
that doesn't have any vif or vbd interfaces (just a 'kernel=' line for
testing), crashes and cleans up after itself, as opposed to crashing and
hanging around. Restarting xenstored obviously breaks the connection to
the Dom0 backend drivers.
