That's not possible, because QEMU doesn't emulate the CPU. The host CPU
must support all of the instructions that would be present in the CPU
that you report to the guest VM.
The reason that the CPU is an option and not directly copied from the
host CPU is that guests might migrate from one physical host to another,
and they may not have precisely the same CPU (and therefore, not
precisely the same set of instructions). In order to make that more
reliable, you can select a CPU whose features are present in all of the
hosts that might run a guest, and that guest is expected to limit itself
to the instruction set in the CPU you've selected.
So, the CPU option allows you to select a less capable CPU than the one
in your host. It does not allow you to select a newer, more capable CPU.
I was afraid of that. Dang! Thank you for excellent
the tutorial.
This looks interesting. M$ put a key into the registry
to bypass the new requirements.
