Proxmox 3.3 iptables + Hashlimit

[Kristof]

Hello.

How I enable hashlimit inside openvz container?

uname -aLinux 2.6.32-32-pve #1 SMP Thu Aug 21 08:50:19 CEST 2014 x86_64 GNU/Linux

lsmod |grep ipt
ipt_LOG 6490 0
ipt_REDIRECT 1888 0

ip_tables 18156 3 iptable_filter,iptable_nat,iptable_mangle

lsmod |grep hash
ip_set_hash_net 27580 2
ip_set 30993 2 ip_set_hash_net,xt_set
xt_hashlimit 10523 0

/etc/vz/vz.conf
IPTABLES="ip_conntrack ipt_state iptable_nat ipt_REJECT ipt_tos ipt_limit ipt_multiport iptable_filter iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_length ipt_REDIRECT"

When I add module xt_hashlimit in vz.conf and restart vz service.

vzctl start 111
Warning: Unknown iptable module: xt_hashlimit, skipped
Starting container ...

I think that something is missing in the kernel (ipt_hashlimit or other).

Do you have any idea? Thanks.
