commit ac63014cfd75cdc4b9c9533899c593044aed8e1a
Author: Ian Campbell <Ian.Campbell@citrix.com>

xen: handle root= in xen-xm configuration files.
    
    In addition to extra= xm supported a root= option which was supposed
    to be incorporated into the final command line. Handle that for "virsh
    domxml-from-native xen-xm". Tested with the libxl backend.
