Thanks Kevin

The machine I wanted to use to try things out does not have KVM support
which is why I asked.... but it seems just possible that a VM might work
with qemu/kqemu even without kvm though I will have to just try it and see
what happens - and although slower than kvm maybe it would not so bad that
it is unusable.  On the machine in question I am happy to play and if it
does not work then it is not a major loss - but worth learning on!
