Hi,

If the devices are in /dev/mapper you are probably using LVM.
You can use these commands to move the disks to server2 substituting
in the names of the LVM logical volume names.

# copy the LV to an image file
dd if=/dev/mapper/<vgname>-<lvname> of=/tmp/<vmname>.img bs=1M

#transfer the image file
scp <user>@server2:/tmp/<vmname>.img

#create a new LV assuming the volume group is already setup
lvcreate -n<lvname> -L<sizeofdisk> <vgname>

#copy the image onto the newly created lv
dd if=/tmp/<vmname>.img of=/dev/mapper/<vgname>-<lvname>

You should now be able to start the VM with the same configuration
file assuming networking etc is setup the same as server1.

Joseph.
