He was talking about running SVM code in KQemu/KVM. It might work with kqemu (I honestly have not tested it, but see no reason it shouldn't),

What would be the problem with supporting that in KVM? The host SVM
should just report that the guest is trying to execute an SVM insn and
generate an Illegal Operation which would be handled by qemu.


Yes, you're completely right about this. The main reason it isn't implemented in kvm is that nobody did it yet. It is actually one of the things on my "would like to do"-list, so if things stay the way they are, maybe you will see this feature in kvm someday.
