libvirt users - Oct 2010 - Mounting an lvm

I converted a system disk from a virtualbox
VM and added to the config on a qemu VM.
All seems well until I try to mount it. The
virtual machine shows data for the disk
image using commands like:

	pvs
	lvs
	lvdisplay xena-1

but there is no /dev/xena-1/root to be 
mounted. I also cannot seem to figure out
whether the lvm related modules are available
for the virtual machine kernel.

Has anyone else tried playing this game?

Not me personally.  But... having the word "xen"
in the name of the lvm volume is kind of worrying.

Xen is an older hypervisor, which KVM is kind of a
replacement for.  So, I'm wondering what else (if
anything) may have gone a bit wonky in the conversion
process.

Do you have the commands you used for converting the
system disk from VirtualBox to QEMU?  If so, can
you cut-n-paste them here?  Thinking there might be
a gotcha or something in that can be pointed out
easily. :)
