Do file /xen/file.img contains only one partition or all the system
(with MBR and so on)?
If /xen/file.img contains MBR (and one or more partitions),
you sholed specify
['phy:VolGroup/guest1,xvda,w']
instead of
['phy:VolGroup/guest1,xvda1,w']
If it works, you can split partitions (insidde /xen/file.img)
to several volumes, in a way described here [1], [2].
