I am curious about the hypervisor layer. I can guess that it's an attempt to abstract away low level hardware changes, a sort of software version of CPU microcode. Or maybe it's a Transmeta kind of thing with dynamic recompilation into a quickly evolving VLIW instruction set. But what's the real reason? --=20 Knowledge Is Power Power Corrupts Study Hard Be Evil --=-VFpadi6cgDfbD80bpLr5 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iEYEABECAAYFAk5MD9wACgkQ1IRuMHS+h7GFJQCffkjluJPTH1n+kN16LXh0r9DR MxUAn2Jvv/zo7tPsxd0Bn+nd6aTrxFES =8UrT -----END PGP SIGNATURE----- --=-VFpadi6cgDfbD80bpLr5--
