Thank you Fajar,
I tried to look at the ip_contrack files that you suggested, but there
are no such files on the server:
root@zaxen01:[~]$ locate ip_conntrack_count
root@zaxen01:[~]$ locate ip_conntrack_max
root@zaxen01:[~]$ uname -a
Linux zaxen01.softdux.com 2.6.18-128.1.16.el5xen #1 SMP Tue Jun 30
06:39:23 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
root@zaxen01:[~]$ cat /etc/redhat-release
CentOS release 5.3 (Final)
Also, there's no firewall running ont he dom0 that blocks anything for
the domU's - I don't quite know how todo this even.
Any other suggestions?
