I'm not very familiar with XEN, but it comes to more interest as CPUs have better VM facilities so I would like to know whether FreeBSD will have amd64 support for virtualization or will it be stuck at i386 as it is with the Linuxulator? Well, I'm mainly interested in HPC, so virtual machines are some kind of 'out of focus' at the moment, I apologize if I lack in rudimenatry knowledge and if someone wants me first having read XEN related stuff (just in case XEN is all over 32 Bit and also Linux has only 32 Bit virtual environments).
