I'm unsure if it's possible to specifiy the absolute dm path for the lv but 
my setups all work with the following settings using a relative path 
(to /dev) for the lv within the vg (not using the dm path), e.g.:

disk = [ 'phy:vg0/lv-rootfs-terry,hda1,w' ]

where the lv ist /dev/vg0/lv-rootfs-terry

$> ls -l /dev/vg0/lv-rootfs-terry
[...] /dev/vg0/lv-rootfs-terry -> /dev/mapper/vg0-lv--rootfs--terry

For your setup it would be
disk = [ 'phy:xenvg/VM1,hda1,w' ]

Daniel
