Xen users - Jun 2007 - Device /dev/mapper/vg00-virt--linuxtest_32--0 is mounted in a guest domain, and so cannot be mounted now.

I tried to start a linux hvm domain (just for testing some things
compared to a pv domain), and it didn''t start up. I then did a
''xm
shutdown'', which didn''t work, then a ''xm
destroy'', and from then the ''xm
list'' function just hung.

I then restarted xend, and ''xm list'' works, but now when I try
to start
the linux hvm domain (linuxtest_32), it says this:

"
Using config file "./linuxtest_32".
Error: Device 768 (vbd) could not be connected.
Device /dev/mapper/vg00-virt--linuxtest_32--0 is mounted in a guest
domain,
and so cannot be mounted now.
"

So I guess xend got broken and didn''t clean something up after itself.
Any suggestions as to how I can clean up that record without rebooting?

Thanks

James

The reason it hung is that my config was still using the 3.0.4
hvmbuilder stuff... I guess that''s allowed although I would have hoped
that xend wouldn''t have suffered such a panic attack...

I removed the entry using xenstore-rm... seemed to work... was it the
right thing to do in that case?

Thanks

That''s strange indeed.

That is what the "xm" tools would do (obviously not running the
xenstore-rm command as such, but removing the entry in xenstore).
