Hi,

I'm trying to deploy openstack's nova on XCP. I hit the problem that
nova agent stuff that needs to be run in dom0 requires arptables and
ebtables to function. I was able to install user-level tools, but
it seems like the kernel-level support is missing:

[root@localhost init.d]# /etc/init.d/host-rules start
iptables: Unknown error 4294967295
iptables: Unknown error 4294967295
FATAL: Module ebtables not found.
The kernel doesn't support the ebtables 'filter' table.
FATAL: Module ebtables not found.
The kernel doesn't support the ebtables 'filter' table.
FATAL: Module ebtables not found.
The kernel doesn't support the ebtables 'filter' table.
FATAL: Module arp_tables not found.
arptables v0.0.8: can't initialize arptables table `filter': iptables
who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
arptables v0.0.8: Unknown arg `--opcode'
Try `arptables -h' or 'arptables --help' for more information.
arptables v0.0.8: Unknown arg `--opcode'

arptables v0.0.8: Unknown arg `--opcode'
Try `arptables -h' or 'arptables --help' for more information.
[root@localhost init.d]# cd /lib/modules/`uname -r`/kernel
[root@localhost kernel]# ls
arch  crypto  drivers  fs  lib  net
[root@localhost kernel]# find . -name "eb*"
[root@localhost kernel]# find . -name "arp_*"
[root@localhost kernel]# ebtables --version
ebtables v2.0.9-1 (June 2009)
[root@localhost kernel]# arptables -V
arptables v0.0.8
[root@localhost kernel]# 

Here's the system info version:

LSB Version:    :core-3.1-ia32:core-3.1-noarch
Distributor ID: XCP
Description:    XCP release 1.1.0-48631c (xcp)
Release:        1.1.0-48631c
Codename:       xcp

Are the modules missing or it's me who's missing something? What is the
proper way to get them installed?
