I can't seem to clear out this information. I tried
/etc/init.d/xend stop
killall xensored xenconsoled
I take it that was with the CORRECT spelling of xenstore?
Verify that there are no xen processes running.
rm -rf /var/lib/xenstored <- has the tdb
rm -rf /var/lib/xend <- has domains, state and storage dirs
but when i startup xend again, xenstore-ls still shows all the old
domains. I must be missing something.
I have successfully removed this file, and the when starting xend
afterwards, the system has no "history" of xenstore data.

It is perfectly fine to remove the xenstore.tdb [filename from memory]
in /var/xen/lib [again, from memory]. Unless of course you actually NEED
some of your old Xenstrore entries for soemthing, but in general, they
are fine to be removed completely.
