First, what little I know about our KVM/Qemu stuff I learned from Adam 
Jimerson, but he's usually a quiet lurker until beer has been 
administered.

But you touched one of my hot buttons: Learning how to admin server things 
via pure shell (ssh/virsh) and editing text config files on the server 
directly will save your bacon when the frying pan is hot. Learn how to 
do it the hard way, and then if you use a browser/gui you have a backup.

For me, it seems there is always some configuration option I need that the
direct interface supports but the idiot point and click level interface 
does not.

Or should that be: Point and click idiot, interface..
