How to mount xvda volumes without xm?

[Mauri Sahlberg <Mauri.Sahlberg@xxxxxxxxxxxxxxxx>]

Hi,

I have a server that has crashed once due faulty hardware which contains 
FC6 with one FC6-virtual machine. We got the machine up but instead of 
it booting to xen-enabled kernel (which was default before last kernel 
upgrade by nightly yum) it booted to non xen-enabled kernel. I would now 
very much like to mount the root-fs of the virtual machine and copy some 
files from it before retrying the boot with xen-enabled kernel. How can 
I do that? The xvda-disk resides on a lvm-volume.

Without the xvda it was easy to mount volumes to host system but how is 
it done with xvda? Is it possible without xen-enabled kernel? The only 
solution for getting files rescued I now know is to use dd to image the 
whole disk, install another FC6 with the same xen-kernel and start the 
virtual machine on it. Very time and disk expensive. I would be very 
gratefull for a simpler and faster solution.

Regards.
