Ah, that made me find a bug where svc wasn't initialized to NULL at the
beginning of ip_vs_genl_set_cmd(). I'm not sure though if that was the
problem or if it still is some general genl issue. I just posted a newer
version version in response to my earlier post, could you give it a try?

Best with this updated ipvsadm:

(later also at http://sixpak.org/vince/google/ipvsadm/)

Thanks,
Julius
