That would triggered by -cpu host, not nesting.

Oh we have -cpu host already?

No, we don't :)

hm - treating the hypervisor bit like any other cpuid bit sounds like a good idea. I'm wondering though which way should be preferred. I usually don't want to have the hypervisor bit set - but maybe I'm the minority.


Windows requires the hypervisor bit to set in order to pass some testing program.
