Hi All,
If you are using XCP/XenServer with DevStack, you might run into some
kernel lockup issues, while you are dding to your cinder volumes, if you
are using the file backed/loopbacked cinder backend. The bug is
described here:
https://bugs.launchpad.net/cinder/+bug/1023755
We worked around this by using a separate virtual drive to back cinder
volumes. I pushed a patch recently, so that devstack supports this kind
of configuration:

Cheers,
