Well, you can use QEMU and it will be extremely slow. I think the qemu-kvm

One thing you can use to speed it up a bit in kmod-kqemu which you can
found
in the RPM Fusion repository, in the Free section (it got GPLed some time
ago, so it's in the Free section, but Fedora won't carry it because it's
not in the upstream kernel). It's a hack to run some of the code on the
native hardware without needing hardware virtualization. That said, I'm
not
sure whether virt-manager will fire up the correct qemu binary and with
the
correct options to use kqemu. If you run the regular qemu binary (not
qemu-kvm) with no option, it will pick up kqemu.
That said, AFAIK kqemu doesn't perform anywhere near as well as KVM, also
because kernel code is still emulated entirely in software (there's an
experimental -kernel-kqemu option which tries to use kqemu also for
kernel-space code, but all I ever got out of that option is VM crashes).
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!
