I'm sure its possible to do that but it may require some hack of
presenting a the original MBR as some type of shadow one for the
guest or other trick. Ric, have you played w/ it?
Xen used to synthesize an MBR in the guest.
As Ian asked above, it's possible to do this with device-mapper too,
although I doubt it's a good idea, but here's how you'd do it anyway:
Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones
virt-df lists disk usage of guests without needing to install any
software inside the virtual machine. Supports Linux and Windows.
