A dom0less domU doesn't have that negotiation with xenstored, as

Thanks for the informaiton. So dom0 needs to send a command in order to
know if Xenstored is up. This is the part I find odd and the event
channel notification could have help to harmonize that part (not the
ring page setup).
Anyway, I seem the only one to think that and I don't have a use-case so
far. So I will not push for it.
