Well, there's a lot of overlap between kvm and qemu, and there's little
setup or black magic needed to use kvm.  What particularly are you missing?

The intent is that kvm be very easy to use to a unix user proficient in
the command line, with the gui junkies served by what virt-manager aims
to be (or competing solutions).

Well, it is a reasonable assumption, but the sad fact is, we do little
regression testing on smp here, and Intel doesn't test AMD for some
reason.  It used to work but regressed.

That's something we need to improve on, and quickly.  I'm counting on
Anthony's plan to flood the known universe with kvm-testing nanobots.

Let us know what's not working and we will try to address it.
