I've seen this a lot when working bug#197 As the number of entries in
/var/lib/xenstored/store/domain/$uuid increase, the time for xend to get
up and running increases. When I had over 500 stale uuid directories in
the store, it took several *minutes* for xend to full come up, and
/var/lib/xenstored was several hundred MB.
The only workaround I know is to:
/etc/init.d/xend stop
killall xenstored xenconsoled
rm -rf /var/lib/xenstored/*
/etc/init.d/xend start
