Yes.

Our startup script has

    if [ -d /proc/xen ] ; then
        log_progress_msg "xen_uio"
        modprobe xen_uio
        if [ "$(cat /proc/xen/domain)" == "pv" ]; then
            log_progress_msg "rte_dom0_mm"
            modprobe rte_dom0_mm xen_phys_addr=y
            set_domU_memsize
            XEN_ARGS="--xen-dom0 --xen-phys-addr"
        fi
