I'm getting some errors in my xen logs and googling has turned up that it's related to iproute2.

I found through google that the key is to enable CONFIG_IP_ADVANCED_ROUTER=y in my kernel config. It turns out, that it is. This link provided more clues.

However, all of these options are enabled in my running kernel, but not as statically compiled modules but as Linux loadable kernel modules.

I'm guessing I just need to add the appropriate module names to /etc/modules

This is what I have in my running kernel config


What do I need to add to /etc/modules to get this working properly?

What command triggers the error message? What is the exact error? – Lekensteyn Feb 10 '12 at 21:12

Those NETFILTER_* configuration options control modules for iptables. To get more information about such an configuration option, you can look it up on a site like In this case, there is no loadable module, the only valid options are "Y" and "N".

For CONFIG_NETFILTER_NETLINK, the module name is nfnetlink:

The configuration item CONFIG_NETFILTER_NETLINK:

    type: tristate
    depends on: (none)
    defined in net/netfilter/Kconfig
    found in Linux kernels: 2.6.25–2.6.39, 3.0–3.2, 3.3-rc+HEAD
    modules built: nfnetlink
