Setting reserved bits is different from setting MBZ bits since the behaviors undefined. If something as common as VMware is depending on being able to set a reserved bit then perhaps the right thing to do from KVM's perspective is to let it. I'm curious if Zach or Jun have any comments about the right thing to do here.
