Install Proxmox VE on Debian Wheezy

Note: 3.0 is currently in beta state, so do not upgrade production server, only testing!

Introduction

The installation of a supported Proxmox VE server should be done via Bare-metal_ISO_Installer. In some case it makes sense to install Proxmox VE on top of a running Debian Wheezy 64-bit, especially if you want a custom partition layout. For this HowTO the following Debian Wheezy ISO was used: debian-wheezy-DI-rc1-amd64.

Suggested partition layout with LVM:

Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         122      975872   83  Linux
/dev/sda2             122        5222    40965120   8e  Linux LVM

LVM:

 LV   VG   Attr   LSize  Origin Snap%  Move Log Copy%  Convert
 data pve  -wi-ao 30.69g 
 root pve  -wi-ao  3.72g 
 swap pve  -wi-ao  1.86g

We recommend to use ext3 filesystem for best OpenVZ performance and stability.

Install a standard Debian Wheezy (amd64)

Install a standard Debian Wheezy (amd64), for details see Debian. Go for a LVM based partitioning and a fixed IP and take care that you have enough free space for snapshots (needed for online LVM backup with vzdump, OpenVZ containers only)

Please make sure that your hostname is resolvable via /etc/hosts, i.e you need an entry in /etc/hosts which assigns an IP address to that hostname.

Install Proxmox VE

Adapt your sources.list

Adapt your sources.list and add the Proxmox VE repository:

nano /etc/apt/sources.list

deb http://ftp.at.debian.org/debian wheezy main contrib

# PVE packages provided by proxmox.com
deb http://download.proxmox.com/debian wheezy pvetest

# security updates
deb http://security.debian.org/ wheezy/updates main contrib

Add the Proxmox VE repository key:

wget -O- "http://download.proxmox.com/debian/key.asc" | apt-key add -

Update your repository and system by running:

apt-get update && apt-get dist-upgrade

Install Proxmox VE Kernel

apt-get install pve-firmware pve-kernel-2.6.32-20-pve

Reboot and make sure to select Proxmox VE Kernel on the boot loader (grub2) - Attention: Default is the 3.2 kernel

Optional - install Kernel headers:

aptitude install pve-headers-2.6.32-20-pve

Now restart the system using the Proxmox VE kernel.

Install Proxmox VE packages

Make sure you are running the Proxmox VE Kernel, otherwise the installation will fail.

Check the currently active Kernel:

uname -a
Linux 2.6.32-20-pve ... 

Remove the Debian kernel:

apt-get remove linux-image-amd64 linux-image-3.2.0-4-amd64

Check grub2 config by running:

update-grub

Install the Proxmox VE packages:

apt-get install proxmox-ve-2.6.32 ntp ssh lvm2 postfix ksm-control-daemon vzprocps open-iscsi

Accept the suggestion to remove Exim and configure postfix according to your network.

Connect to the Proxmox VE web interface

Connect to the admin web interface (https://youripaddress:8006) and configure the vmbr0 and review all other settings, finally reboot to check if everything is running as expected.

Optional: Developer Workstations with Proxmox VE and X11

Proxmox VE is primarily used as virtualization platform with NO additional software installed. In some case it makes sense to have a full desktop running on Proxmox VE, for example for developers using Proxmox VE as their primary workstation/desktop.

For example, just install LXDE desktop and Chromium browser:

apt-get install lxde chromium

If you prefer XFCE4:

apt-get install xfce4 chromium lightdm

Make sure network-manager is not used, else pve-cluster will not start in some cases

apt-get purge network-manager

Don´t forget to install Oracle (Sun) Java, see Java_Console_(Ubuntu)
