Forgot to say there's an additional twist here.  It won't affect you
with F11+ guests [see bug below], but might affect people installing
older versions of Fedora or other Linux distros.

LVM doesn't support having two volume groups with the same name.
Normally not a problem, but if you insist on using whole physical
drives, and if the guests have the same volume group name as each
other or the host, that can cause serious problems.

Another reason why using whole physical drives is a bad idea ...
