Hi,
I am writing a kernel module in dom0 to watch for @introduceDomain.
The callback procedure is prototyped as (registerd with
register_xenbus_watch()) :
static void new_domain(struct xenbus_watch *watch, const char *node)
In this callback, what we can get is node=="@introduceDomain" when
the watch fired. Is that all we have? If I want to know which domain
(include domain-name and domid) caused this event, where to look for?
Many Thanks.
Hieu

I have a patch to extend the watches to include arbitrary data
specifically so we can get the domain id for an
@{introduce,release}Domain watch.
Just waiting for some feedback on it...

Great. Otherwise I must enum for the domains myself.
Thanks.
