virsh doesn't place any restrictions on whether those commands can
be run on inactive guests. It should just try the API regardless
and be prepared for any errors.

If XenD supports this then it should be just a matter of removing the
check from xend_internal.c   PinVcpu method

   if (domain->id < 0) {
        virXendError(domain->conn, VIR_ERR_INVALID_ARG,
                     _("Domain %s isn't running."), domain->name);
