Proxmox running on ubuntu using virtualbox

The environment used for this guide

• A 64-Bit Intel Core i5 Laptop, 8Gb Ram.
• Ubuntu 11.10 Maverick AMD64 (The “host”)
• VirtualBox
• Access from host running VirtualBox only (so useful for development/proof of concept)

The proposed environment

• Proxmox “Public” Network: 172.241.0.0/25
• Proxmox “Private” Network: 10.0.0.0/8
• Host has access to its own LAN, separate to this on 192.168.0.0/16 and not used for this guide

The Guide

• Install VirtualBox sudo apt-get install virtualbox
• Under Preferences… Network…
• Add/Edit Host-only network so you have vboxnet0. This will serve as the “Public interface” to your proxmox environment
  • Configure this as follows
    • Adapter
      • IPv4 Address: 172.241.0.100
      • IPv4 Network Mask: 255.255.255.128
    • DHCP Server
      • Disable Server

  Create proxmox server.

  • Name: PROXMOX
    • OS Type: Linux
    • Version: Debian (64-Bit)
  • Minimum 2048Mb Ram (recommended to use more if needed)
  • Boot Hard Disk
    • Dynamically Expanding Storage
    • 8.0Gb (lager depending on amount of vm’s) or if seperate disk will be created and mounted.
  • After this initial set up, continue to configure the guest
    • Storage:
      • Edit the CD-ROM so that it boots proxmox ISO (http://www.proxmox.com/downloads/proxmox-ve/17-iso-images)
      • Ensure that the SATA controller has Host I/O Cache Enabled (recommended by VirtualBox for EXT4 filesystems)
      • Change the IDE controller from the default PIIX4 to ICH6
    • Network:
      • Adapter 1
        • Host-only Adapter
        • Name: vboxnet0
        • IPv4 Address: 172.241.0.101
        • IPv4 Network Mask: 255.255.255.128
      • Adapter 2
        • NAT
        • This will provide the default route to allow the VM to access the internet to get the updates.
    • Audio:
      • Disable (just not required)
