The Proxmox Mail Gateway 2.1 2 template is an OpenVZ OS template that allows you to run the Antispam & Antivirus Mail Gateway. Proxmox runs in different virtualization environments but in OpenVZ it is almost twice as fast as with full virtualization - due to the minimal overhead. Proxmox offers free and commercial licenses.

I assume you have already a running OpenVZ server. This HowTo howto is based on an fresh Centos CentOS 4.4 installation with OpenVZ kernel 2.6.9 but should also work with all other combinations. I used a Dual Xeon with 2 GB RamRAM.

Create a reasonable default config if you don’t have one. The following command creates the file <code>/etc/vz/conf/ve-default.conf-sample </code> which contains reasonable defaults if you plan to run 5 VEscontainers:<pre> vzsplit -n 5 -f default</pre>

== Create a VE container ==

Choose a free VE CT ID, we use 777 for this guide.

<pre>vzctl create 777 --ostemplate debian-46.0-proxmox-mailgateway-2mailgateway_3.1 --config default</pre>

== Configure the VE container ==

Set IP Address address and DNS nameservers, start servers automatically at boot time: please adapt these settings to your environment.

<pre> vzctl set 777 --onboot yes --ipadd 192.168.2.110 \ --nameserver 192.168.2.100 --nameserver 192.168.2.101 \ --hostname proxmox --searchdomain yourdomain.tld --save</pre>

Set guaranteed memory to 512MB1024MB, maximum disk space to 4GB.

<pre> vzctl set 777 --vmguarpages 512M1024M:unlimited --privvmpages 1G:1100M --diskspace 4000M:4400M --save</pre>

== Start the VE container ==

<pre> vzctl start 777</pre>

<pre> vzctl set 777 --userpasswd root:YOURPASSWORD</pre>

The Proxmox HA Cluster consists of a master and several nodes (minimum one node) — all You can be run the mail gateway on different any OpenVZ servers within platform and on the same subnet[http://pve. Configuration is done on the master, all configuration proxmox.com/wiki/Proxmox_VE_2.0_Cluster Proxmox VE Cluster]. This include live-migration and data is synchronized to all cluster nodes over a VPN tunnelonline backups.

For online backups, see [[backup of a running VE container with vzdump]].
