Is this information still available after a domain has been destroyed? I
was expecting that the watcher of @releaseDomain was only notified of a
domain destruction after the domain had been completely destroyed so
there would be no information amount the domain available any more. Are
you saying the would still be qemus/xenstore information available for
the domain, and if so how does it get tidied up?
Anthony.
