available on the Parallels server, the cat /proc/meminfo command executed inside a

configuration file. If you do not want the applied changes to persist, you can omit the --save

Loading iptables Modules
The given section provides information on how you can manage iptables modules on the
server and inside particular Containers.
Loading iptables Modules to Parallels Server
You can configure a list of iptables modules that will be loaded on the Parallels server after
its startup by editing the /etc/vz/vz.conf file. The IPTABLES parameter in this file
determines the iptables modules that will additionally be loaded to the server during the
Parallels Server Bare Metal startup. For example, you can indicate the following iptables
modules as the value of this parameter to have them automatically loaded to your Parallels
server after the Parallels Server Bare Metal startup:
IPTABLES="ipt_REJECT ipt_tos ipt_limit ipt_multiport iptable_filter
iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_length"
All the specified modules will be loaded on the server startup once you restart it.
