[Xen-users] can ping domU VPS, but can't SSH into it

[Rudi Ahlers <rudiahlers@xxxxxxxxx>]

Hi all,

A client just phoned me and said he could not SSH into his VPS, yet he
can ping it. So, I login to the host node, and check it out, can't SSH
into. I shutdown iptables on the VPS (via xm console serverza.vm) but
still can't SSH into it. I restart the VPS, still can't SSH into it.

So, I check the host, and found this in /var/log/messages:

Jul 22 19:19:07 zaxen01 kernel: device vifserv0 left promiscuous mode

networking for guest domains.

Does this make any sense at all? why / how wouldn't the ip forwarding
be setup? The other 3 VPS's on the same node works fine though
