CentOS - Aug 2008 - can't access irc server on xen domU, please help

Hi all,

I'm running a CentOS 5.2 server with a FC8 xen domU guest, and an irc server
on the FC8 domU guest. For some odd reason, I can't access the irc server on
the xen domU guest.
>From FC8, when I run netstat -a, I can see irc is listening:
netstat -a
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address               Foreign Address

LISTEN

and running nmap on the localhost looks promising as well:

netstat -a

LISTEN
tcp        0      0 *:ssh                       *:*
LISTEN



Yet, from the outside (either from another PC, or the dom0 itself), I can't
connect to the irc ports.

I've even disabled iptables on the dom0 altogether, but stil can't
connect
to it.


The only open ports are:
PORT     STATE  SERVICE
80/tcp   open   http
443/tcp  closed https
7001/tcp closed afs3-callback
8000/tcp closed http-alt
8080/tcp closed http-proxy
8081/tcp closed blackice-icecap




How do I get this to work?

P.S. Sorry for the cross-post, for those of you who are on the centos-virt
list as well, I just find that this list is being used more.

Compare that with your lists above. It doesn't fit at all, e.g. there is 
no https on your other lists. Looks very much like a dns or IP address 
problem - the latter test is not against the same target although you 
think it is.
