Hmm, no, seems to be a missing hotplug event.

I've added a debug line to xen-backend.rules:

SUBSYSTEM=="xen-backend", RUN+="/bin/logger -p daemon.debug -- 
xen-backend: $env{ACTION} %k"

A successfull start looks like this:

   Oct 27 17:34:50 master-xen logger: xen-backend: add vbd-19-768
   Oct 27 17:34:50 master-xen logger: xen-backend: add vbd-19-832
   Oct 27 17:34:50 master-xen logger: xen-backend: add vif-19-0
   Oct 27 17:34:50 master-xen logger: xen-backend: online vif-19-0

With broken network the "online" event is missing:

   Oct 27 17:35:31 master-xen logger: xen-backend: add vbd-20-832
   Oct 27 17:35:31 master-xen logger: xen-backend: add vbd-20-768
   Oct 27 17:35:31 master-xen logger: xen-backend: add vif-20-0

Oh, and btw, reboot doesn't work all the time either.  Sometimes the 
domain comes up again as it should, and sometimes it doesn't.

cheers,
