All Intel machines sold after ~2010 should have unrestricted guest support. (HAX doesn't support AMD, but anyway AMD's virt extensions have always had the equivalent feature). I'm not sure we want !UG support at all but, if we do, QEMU 2.9 will have multithreaded TCG so it would be possible to make it less intrusive. So it's worth starting with the minimum patchset and see what happens. Thanks for working on this! Paolo
