This has networking caveats. If you run the qemu binary directly as a
regular user, the easiest setup is -net user, which doesn't actually
have full networking capabilities. You'll want to study up before you
take this route.

Unfortunately that code isn't upstream yet. I know Dan Berrange has
something working to a degree, but it hasn't been posted yet.

You can also try to use SDL for graphics rather than VNC. This has some
caveats: no remote access via libvirt, the SDL console will pop up
outside of virt-manager, and when the SDL window closes the guest will
be forcibly powered off. I haven't tried this, but AFAIK sound should
work. You can try changing the sdl audio backend in
/etc/sysconfig/libvirtd from 'pa' (pulseaudio) to something else if you
have issues.

Hope that helps,
Cole
