Well, on the bare metal I do have...
root@latin ~ # cat /sys/module/kvm_intel/parameters/nested
Y
...so I was under the impression that that should just work? I now see
that you also need to configure the host VM to have particular CPU bits
set, so maybe that was my mistake.
Anyway, since this is just meant for a test setup it's not critical, so
if my new attempt doesn't work I'll try the qemu thing.

Well, between this and the above and a few other mistakes I'd made, I
decided that starting over would be a good idea, so I destroyed the
containing VM and started over from scratch. So I can't test this right
now, but I think I couldn't do "terminate" since the VM wasn't
running...

I did have some network up, but I don't know whether it worked :-)
