hi,
there's a bug in xen 2.0 which can be replicated by installing
udev on the xen master.
if you have udev - and no scsi devices present - on the xen
master, and you specify sda1234 etc as the disk partition
names in the /etc/xen/xen-guest-spec-files, then the xen
guest WILL NOT START.
... what has the existence or otherwise of /dev/sda1 on the
xen master machine got to do with the guest OSes?
to "fix" this problem, you must cp -aux /.dev/sd* /dev.
