Even if you request "host" CPU model, the guest will always see only a
subset of features the host supports. Not all features can be used in a
virtual machine and even if they can be used they usually need some
support form KVM or QEMU or both. That is both KVM and QEMU will filter
out features they cannot currently virtualize and thus you will get a
smaller set in comparison to the host CPU.
