virt-df lists disk usage of guests without needing to install any
software inside the virtual machine.  Supports Linux and Windows.
http://people.redhat.com/~rjones/virt-df/

BTW this now provokes lots of (non-fatal) warnings like this:

./../src/session.c:26912: warning: guestfs_session_zgrepi is deprecated in the
inline comments, but no deprecation guards were found around the declaration.
(See the --deprecated-guards option for gtkdoc-scan.)
