The partitition specifications there are for a partition based hypervisor (Xen) and won't work with the vanilla vmbuilder on KVM. The patch just makes it work with the same data.

Thanks, Neil. Whenever you get a chance to create those bugs, just assign
them to me and point back to this tree, and I'll cherry-pick the relevant
commits once I verify the testcases.
