Thanks. Given another keyword, I was able to find this page:
https://help.ubuntu.com/community/Kqemu
My server is still running 9.10, so it looks like I could build rebuild
qemu from source and enable kqemu, but that defeats my purpose. There
is a comment at the top of that page that suggests that qemu would run
without either kvm or kqemu -- just that it would run poorly. Since I
am just interested in testing some web apps, poor performance might not
be much of an issue. Any thought on that?
I suppose my other alternative would be to do my testing in a VM under
VirtualBox on my desktop.
