No stock OpenVZ kernel, see http://download.openvz.org/kernel/branches/
for the available OpenVZ kernel branches. 2.6.32 is the most recent.

Please note that wanted to provide fix to your problem, which is hardly
an ideal solution. You might want to read my reply to KB post and
my emphasis on keeping a "clean" distribution.

So your kernel is missing the required iptables kernel module too.
I really doubt that you've permission to load a kernel module from
inside of an OpenVZ container. AFAIK this must be done on the host.

Once the kernel module is loaded, you can try if your stock iptables
works. If not, you'll have to try a newer release as I suggested in the
first place.
