FreeBSD dom0 support is PVH mode only. The Xen code does not support AMD CPUs with PVH so this is not unique to the FreeBSD port. I saw a couple of patches floated on the Xen list but they never got committed. Roger would know more about their fate. Matthew is right, there's no AMD support at the moment. I'm currently reworking the whole PVH concept inside the hypervisor, because what's currently inside of Xen is not sustainable in the long term: http://lists.xen.org/archives/html/xen-devel/2015-08/msg00512.html This series is going to miss the next Xen version (4.6, which is due in less than a month probably), but I'm very positive it's going to make it into 4.7.
