 SECURITY
-    The current code is probably not secure against malicious guests. In
-    particular a malicious guest can set up a disk in such a way that disk
-    structures with loops can cause virt-df to spin forever. We are
-    preparing a parsing library which can fix these sorts of problems.

-    In the meantime, do not run virt-df on untrusted guests.
