You bootstrap yourself via xenbus. You have a pre-agreed location in

I imagine that we can get rid of event channel, and use xenstore to
notify. That is certainly OK, but I doubt about its efficientcy. What
do you think?
Very mad. It's easy to set up an inter-domain event channel betwene
domains A and B:
1. A executes something like evtchn = EVTCHNOP_alloc_unbound(B)
2. A writes 'evtchn' into xenstore.
3. B reads 'evtchn' from xenstore
4. B executes something like EVTCHNOP_bind_interdomain(A,evtchn)
