Xen users - Mar 2006 - mounted in a guest domain?

Hi,

I''ve having the following error when trying to ''xm create
xentest'':

Error: Device 769 (vbd) could not be connected.
Device /dev/lvmxen/xentest is mounted in a guest domain,
and so cannot be mounted now.

Which doesn''t make any sense because I don''t have any
domU''s starting at
boot so nothing could be using the device. I do a fresh boot with no auto 
domU''s then do ''xm create xentest'' and get that
error. Anybody else have
this problem? I''ve managed to have it go away after rebooting several
times
but then usually the next reboot it''s back again.

Thanks.

I figured out the problem about 10 minutes after emailing the list. My 
/etc/init.d/xendomains script wasn''t linked right for startup/shutdown.

First I had to kill the hung vbd with ''xenstore-rm
backend/vbd''

on my debian machine I had
update-rc.d xend defaults
update-rc.d xendomains defaults

but it turns out you need xendomains to start after xend and shutdown before 
xend for everything to work correctly. Since debian gives a run level of 20 
by default I just changed

update-rc.d xendomains defaults 21 19

and everything works.

Thanks.
