PV = ParaVirtualized guest.

Correct, virt-manager is a usable GUI. I've never used it on Debian
though (which is the OP environment), so I can't comment whether or
not it'd be the best choice.

Usually you wont'have to :)
Some scenarios where it would be useful:
- you have a PV-aware OS (RHEL5, for example), but for some reason you
want to install directly from DVD (which is not supported for PV
guest)
- you have a PV-aware OS, working great on a  physical machine or
other virtualization solution, and you've succesfully convert it to
HVM guest (using some P2V method), but you need more performance only
available from PV guest.
- fun experiment :D

Take a look at this thread for a how-to
