Well some versions of Xen are buggy, but not neccessarily all of
them. IMHO we should support it in libvirt because it is a trivial
change to make. This at least lets users try the functionality and
see if there are bugs in their version of Xen

eg, our code already does

    return xend_op(domain->conn, domain->name, "op", "dump", "file", filename,
                   "live", "0", "crash", "0", NULL);

so it is easy to set   "live", "1"   based on flags
