This kept the virtual CPU reproducible across hosts while exposing the minimum features then needed for nested KVM. AMD was switched to host passthrough in 3.20.3 (2016), because kvm64 model did not work reliably there. QEMU now considers kvm64 a legacy model [1], and current KVM documentation recommends host passthrough [2]. Using kvm64 hides modern cpu capabilities and can make guest load run very slowly. Use host passthrough for native x86_64 KVM on both Intel and AMD. The explicit user-provided -cpu option is still honored.
