List-Id: qemu-devel.nongnu.org List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Cc: kvm@vger.kernel.org From: Jes Sorensen KVM has a minimum CPU requirement in order to run, so there is no reason to default to the very basic family 6, model 2 (or model 3 for qemu32) CPU since the additional features are going to be available on the host CPU.
