Right. The fact that this has been lingering in the source for years on
end and only now is being announced as a tech preview seems to answer my
question in the sense that "no this is not possible" :S .

Guess I'll have to fire up my build vm then and see if nuking that test
for "kvm_nested" allows me to pass the svm cpu flag from a C6 host.

Leonard.
