Hi,

I just had this problem. When you compile your dom0 kernel you need to include IP tables modules. These can be found when configuring your kernel with:

make menuconfig

from in the dom0 kernel directory. The location of the modules is under:

Networking  ---> Networking options  --->  Network packet filtering
(replaces ipchains)  --->  Core Netfilter Configuration  --->  Netfilter
Xtables support (required for ip_tables) and do enable all modules
included in that as per your need.

Then go to - Networking  ---> Networking options  --->  Network packet
filtering (replaces ipchains) ---> IP: Netfilter Configuration ---> IP tables support (required for filtering/masq/NAT)

(Thanks to Sadique who found this).

Hello, I compiled/installed Xen3.0 from source (xen-3.0.2-src.tgz) and Dom0 is up and running but at startup I am having the same errors with iptables. I am a beginner with kernel compiling and customizations and my question is which "menuconfig" file do I edit? After untar of the (xen-3.0.2-src.tgz) package, ls command gives:
[root@zenki xen-3.0.2-2]# ls
buildconfigs  Config.mk <http://Config.mk>  docs    install.sh            
Makefile  README  xen

ChangeLog     COPYING    extras  linux-2.6-xen-sparse  patches   tools

and how should the entry look like?
much thanks!

Thanks Sadique! That was it, I just couldn't find it.


(compiling away now)

Cheers,
Julius.

It's there in xen kernel, but you need to add that.

make menuconfig
Networking  ---> Networking options  --->  Network packet filtering


(replaces ipchains)  --->  Core Netfilter Configuration  --->  Netfilter
Xtables support (required for ip_tables) and do enable all modules
included in that as per your need.

filtering (replaces ipchains) ---> IP: Netfilter Configuration ---> IP tables support (required for filtering/masq/NAT)

You can only go to the second step after doing the first one.

Thanks
Sadique

Hi,

I have a dom0 up and running now, however I have the following error
(FATAL: Module ip_tables not found.) when iptables tries to start. It
looks like it needs to be compiled and inserted however it doesn't


appear to be an option in the kernel configuration.

Does anyone know if it necessary to download iptables source and
compile or is it possible to have it part of the xen kernel when
building from source?



Cheers,
Julius.
