[Xen-devel] problem starting hvm domain with stubdoms with "xl create"

[Jeremy Fitzhardinge <jeremy@xxxxxxxx>]

xl create is failing with a timeout waiting on the device model.  I'm
pretty sure its because its looking at the wrong domid for the device
model (the main domain's, not the stubdom; I added to the log message to
print which domain it's waiting on), but I haven't tracked down a
specific fix yet.
