Ideally I would like the FreeBSD DomU to serve = ZVOLs and NFS to other DomUs. Whether or not you can run HVM does not depend on the CPU, but on XEN = and which loader you use (e.g. qemuloader). So the best thing you can do = is actually to run a HVM machine and use the stock kernel. That = automatically detects which PVHVM stuff may be available and uses it = when it is there. It should support multiple processors just fine, I have not tested the = RAM amount myself, but don=92t see a reason why it would be a problem. most important part of my config is this: kernel =3D '/usr/lib/xen-4.0/boot/hvmloader' device_model =3D '/usr/lib/xen-4.0/bin/qemu-dm' builder =3D =91hvm' Regards, Jeroen.
