That's easy, after you
modprobe -v kvm-intel
you will have /dev/kvm. You can then give yourself rwx permissions by
group, or whatever. I am in root group, so I just
chmod g+rwx /dev/kvm
to get it done. Some of the docs claim selinux has to be disabled, I'm
not willing to do that (yet) as all the non-networked stuff works just
fine as is. I build software under BSD, run Windows applications, etc.
But the network stuff doesn't want to work, even when I create a bridge,

There is bridge module and utility stuff to download, the machine on
which I did it is offline (and FC6) at the moment, so I can't give details.
I never did get kvm working for network access, and I'd rather use it
than xen if I could, so if you get it done a one screen howto would be
useful. There's some stuff I pulled off virtual.org (from memory)
