Subject: Hardware support for secure virtualization (was: About Xen: maybe a reiterative question but ..)
Date: Thursday, October 25, 2007 - 6:50 am

With all this discussion some questions went to me:


what's the hardware needed to do full and secure (para)?virtualization ?

is there some arch with this support ever created?

could the virtualization environment be secure if all guest OSes run in

userland? (User-Mode Linux, QEMU without acceleration, ...)


Thanks in advance
