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.)
- milcron 10y agoCorrect. 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.
- dom0 10y agoWasn't TdR statement before hardware virtualization on x86 became commonplace? Before AMD-V / Intel VT x86 virtualization worked through bizarrely complex techniques (binary translation...)
- milcron 10y agoHe 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. https://en.wikipedia.org/wiki/X86_virtualization https://en.wikipedia.org/wiki/X86_virtualization
