There does seem to be a problem with the hotplug scripts either not running at
all or bailing out early.  Please could you put some tracing into the relevant
scripts -- /etc/hotplug/xen-backend.agent,
/etc/hotplug.d/default/default.hotplug, and / or
/etc/udev/rules.d/xen-backend.rules, depending on your system, and see if you
can figure out whether the hotplug event is firing at all, and if it is, where
the script bails out.

To have got the device in /sys/devices/xen-backend tells us that it's managed
almost everything before the hotplug scripts get started, so this shouldn't be
difficult to track down.

Thanks,

Ewan.
