Hmm, I had some trouble as well with a LVM setup.  Cause seems to be
that the device mapper block devices get a different major number
depending on whenever it runs on native linux or on xen.  On my system
it sucessfully mounted the root fs, but bailed out shortly after when
trying to check the filesystems.  So it was a different (but maybe
related) issue.

Setting HOTPLUG_DEV_ON_TMPFS to "yes" (in /etc/sysconfig/hotplug) and
then let udev create all the device nodes dynamically at boot time
fixed it for me.

HTH,
