Is that a quad-core CPU or a quad-CPU system? If it's a quad-core CPU, it should support Intel hardware virtualisation feature. If it does, you don't need any Xen patches or support in FreeBSD. Just create a Xen VM that supports hardware virtualisation (not a paravirtualised VM) and install FreeBSD as per normal. That's the beauty of the Intel VT and AMD VX (or whatever they call it now) features -- no need to patch an OS to run in a Xen VM. Freddie, My system is a Intel Core2 Quad Q6600 on a Intel Desktop Board DP35DP ( http://www.intel.com/products/motherboard/DP35DP/index.htm ) with 4Go Memory. Dom/0 currently runs with a Ubuntu 7.10 ( amd64 version with Linux 2.6.22 and Xen 3.1 ). So yes this CPU supports all what PAE,VMX, ... Yesterday I created some LVM logical volumes and tried to install some Xen DOM/U systems like NetBSD, FreeBSD and also would like to try some OpenSolaris, OpenBSD .. So I googled a bit to find some installation kernels but got very surprised. First of all I tried NetBSD and found some pre-compiled kernels for NetBSD-4.0 but get problems with it. Xen Dom/0 claims with a incompatible kernel version because it does not support xen-3.0-x86_32. The only thing I see with xm info is xen-3.0-x86_32p. I suppose "p" letter is for PAE. So I am now blocked because I do not know if I have to use Dom/U amd64 or Dom/U i386 systems, if I have to compile kernels with PAE support or not. Concerning FreeBSD, I also searched for pre-compiled kernel but only found link specified in my previous mail. As I said it it seems possible to get last snapshot from Preforce Repository but I do not get any account on it and I do not know how and what I have to do just to get copy of the sources and applied the difference on last cvsup snapshot. So maybe I will be able to compiled a xen-3.0-x86_64 FreeBSD-7.0-Dom/U kernel. Finally I am not sure to really understand what you explained above with virtualized and para-virtualized kernel. As I understand it, we get two ways to install a Dom/U system. System that's not Xen compatible but that can be installed through support for Intel VT ( e.g. Windows 2003 Server ). This runs with a hvm loader. The other way is with kernels that are Xen Dom/U compatible like BSD's and Linux based systems. Linux and NetBSd are already running fine with Dom/U Dom/0. Other BSD's are are still making effort to support it correctly. Thanks to help me.
