FATAL: Module ip_tables not found

Hi,
has anybody an idea or expiriences with iptables on Oracle VM 3.0 ?
It seems to be missing in OVM 3.0.1 ??

[root@ovm3bx960s1 ~]# iptables -L
FATAL: Module ip_tables not found.
iptables v1.4.7: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

[root@ovm3bx960s1 ~]# lsmod | grep table
[root@ovm3bx960s1 ~]#

[root@ovm3bx960s1 ~]# insmod ip_tables
insmod: can't read 'ip_tables': No such file or directory

[root@ovm3bx960s1 ~]# service iptables start
iptables: Applying firewall rules: FATAL: Module ip_tables not found.
