Playing around with the release candidate of Xen-4.4 I seems to have problems
launching a PV guest with a config that used to work with Xen-4.3. The normal
logging would hint problems with the NIC setup (witch the slightly confusing
origin of vtpm).
Comparing the output to one produced by xen-4.3 I found a weird deregister of a
watch never registered (see below) instead of a call to the hotplug script.
Am I doing something wrong?

This second watch getting unregistered, I do not get in xen-4.3. Also there
never seems to be a register with that handle. In 4.3 at this point the hotplug
script gets called.

CC'ing IanJ - this looks related to the recent libxl events/forking work.

It seems you are missing a xencommons init script update, see commit
