I have very little knowledge about XenClient, but I think the issue is that you are trying to load a PV kernel inside of an HVM guest, which is never going to work. PV kernels need to be started in a special way by the toolstack/hypervisor, so just installing FreeBSD from an ISO and trying to replace the GENERIC kernel with a XEN one is not going to work.
