First we install debian lenny. There is many howtos in this topic, so I will assume that it`s done.

Now on fresh debian minimal install we add to /etc/apt/source.list as below:

deb http://rasta.struction.de/pve-1.4-i386/ ./

Then issue:

apt-get update

aptitude install proxmox-ve ntp ssh lvm2

Then we accept and agree to every aptitude suggestion. At this moment You will be asked also to confirm changes by writing Yes.

Now we wait. Notice that Your kernel will change to linux-image-2.6.26-2-openvz-686. That is very good 🙂 Remember to install and check boot loader before You reboot. System may become unbootable 😛

reboot

After successful reboot enter Your linux box ip address in the web browser and login using Your root password on Proxmox interface login page.

Have a nice day 🙂

p.s.

For proxmox it is usefull to create bridge interface, so virtual machine interface can be added to this bridge. To do this edit file /etc/network/interfaces to fit Your needs, an example:

# network interface settings
auto lo
iface lo inet loopback
iface eth0 inet manual
iface eth1 inet manual
auto vmbr0
iface vmbr0 inet static
        address  192.168.1.100
        netmask  255.255.255.0
        gateway  192.168.1.1
        bridge_ports eth1
        bridge_stp off
        bridge_fd 0
