OK, I'm not going to insist on that, but my plans for FreeBSD is to make the native entry point capable of booting inside of a PVH container up to the point where cpuid (or whatever method) can be used to detect the environment. Do you recall what's preventing the native entry point from booting inside of a PVH container? If certain emulated devices not present are needed at early boot we could look into either replacing them with other options available inside of a PVH container, or as a last resort making them available on a PVH container.
