ACK, confirmed Linux treats them identically

  drivers/xen/core/reboot.c

THe control/shutdown  xenstore watch fires shutdown_handler(), which
sets up a job for __shutdown_handler(), which runs shutdown_process()
which does

        if ((shutting_down == SHUTDOWN_POWEROFF) ||
            (shutting_down == SHUTDOWN_HALT)) {
                if (call_usermodehelper("/sbin/poweroff", poweroff_argv,
                                        envp, 0) < 0) {

Semantically 'poweroff' is what we're wanting for virDomainShutdown().
