Also I didn't notice this went to xen-devel@, which is a list for
_development_ of Xen. User support and configuration issues belong on xen
-users@.

If I had noticed this I would have added -users to the CC and moved -devel
to BCC in my previous reply. If you see this before you reply to my
previous mail please adjust the Cc's appropriately, otherwise please try
and remember to use the appropriate list next time.

Thanks,
Ian.
