Just for the record, so does KVM if you turn on ksm. It actually
works very well for a free solution.
I use Qemu all the time, with hardware assist. How would I turn on ksm?

I do it by putting this in a script that gets run at bootup. My numbers
are relatively arbitrary and are designed to work slowly with a low load

for my use case it just made things more complex for no real gain.
