Why are you changing this? Unless you've gone through extra steps to configure your guest OS to use this different driver and location of the boot disk, it's going to fail to boot. Perhaps try leaving this line unchanged and see how that goes. From the VM's perspective, the copy-on-write image (delta) is no different than the backing store.
