As I expected: Suse-10.1 simply does not have proper driver for virtualized disk-controller. It can not mount /dev/sda1 simply because it does not see it. Try edit VM-properties and change disk-controller to something very common. You know, 10.1 is very old version, with some quite outdated 2.6.x kernel. It lacks support of a lot of modern hardware. Or simply first upgrade physical machine from 10.1 to 12, and then convert p2v.
