Editing Proxmox Mail Gateway in container

The Proxmox Mail Gateway 2.2 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. 

== Prerequisites ==
I assume you have already a running OpenVZ server. This howto is based on an fresh 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 RAM.

== Installation ==
Download the Proxmox OpenVZ template:
 wget ftp://download.proxmox.com/appliances/mail/debian-4.0-proxmox-mailgateway_2.5-1_i386.tar.gz

Copy the template into the template cache, usually to /vz/templates/cache/

== Create a default config ==
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 containers:
 vzsplit -n 5 -f default

== Create a container ==

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

<pre>vzctl create 777 --ostemplate debian-4.0-proxmox-mailgateway-2.5 --config default</pre>

== Configure the container ==

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

 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

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

 vzctl set 777 --vmguarpages 512M:unlimited --privvmpages 1G:1100M --diskspace 4000M:4400M --save

== Start the container ==

 vzctl start 777

And finally set the root password:
 vzctl set 777 --userpasswd root:YOURPASSWORD

Now you have a running Proxmox! By typing vzlist you should have something like this.
<pre>[root@vz1 ~]# vzlist
      CTID      NPROC STATUS  IP_ADDR         HOSTNAME
       777         56 running 192.168.2.110   proxmox
[root@vz1 ~]#</pre>

== Backup considerations, live migration, and HA Cluster ==
The Proxmox HA Cluster consists of a master and several nodes (minimum one node) — all can be run on different OpenVZ servers within the same subnet. Configuration is done on the master, all configuration and data is synchronized to all cluster nodes over a VPN tunnel. 

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

For live migration, see [[checkpointing and live migration]].

For HA Cluster, see [[HA cluster with DRBD and Heartbeat]] and [http://www.proxmox.com/proxmox-mail-gateway/features feature page on Proxmox].

== Proxmox configuration ==
For the Proxmox configuration point your web browser to the given IP address.
