I have this problem too. In my case it seems to be the very short timeout
for starting backend devices. Basically, AFAICT, all vif- scripts must
finish within 10 seconds or the xm create command is aborted.

In my case I do a lot of dynamic configuration in vif-nat and it often takes
much longer than 10 seconds, especially if I'm running a kernel build or
something in the background.

You can see if this is the same problem you're having by changing the
timeout DEVICE_CREATE_TIMEOUT in
/usr/lib/python/xen/xend/server/DevController.py (probably around line 28)
to something larger than 10.
