You do know that OpenBSD just recently introduced a hypervisor, right?

(From the "(historically)", I'm guessing you do but others reading this may not realize that OpenBSD now does ship with a hypervisor. It's very "early", though, FWIW.)

Correct. Currently it can only run OpenBSD guests, and it only supports x86.

The landscape is a little different now that hypervisors are no longer cutting edge, and the x86 architecture has improved virtualization abilities which help prevent some security flaws.

Wasn't TdR statement before hardware virtualization on x86 became commonplace? Before AMD-V / Intel VT x86 virtualization worked through bizarrely complex techniques (binary translation...)

He said that in ~2007? So that may be correct. x86 hardware virtualization has gone through several generations so his comments may have remained accurate even as hardware features were added.

Hardware-assisted virtualization really took off in ~2008, but they've continued to add features over the past decade.
