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.

I tried brute-forcing it by making libxl_wait_for_device_model() try to
find the stubdomid for the given domid and use that if present. That
appeared to work in that it avoided this particular problem, but xl
immediately decided the domain had rebooted and sat in a loop repeatedly
constructing and rebooting the domain until I forcably killed it.
I also tried making libxl_create_stubdom() set (*starting_r)->domid =
domid; (rather than info->domid), which had the same effect.
So at this point I'm not sure what's going on.
