VMfest Base Image

I’m playing with Pallet to setup an IRC server and bouncer. Pallet uses vmfest to deploy to VirtualBox.

While vmfest comes with some prepared images, I found that my laptop would not run them, so I made my own, with a lot of help from Antoni Batchelli.

  • Create an image in VirtualBox with a NAT and host-only network.
  • Install your favourite distro.
  • Install an SSH server.
  • Setup passwordless sudo
  • Make sure /etc/network/interfaces contains both eth0 and eth1.

      auto eth0
      iface eth0 inet dhcp
      auto eth1
      iface eth1 inet dhcp
  • Update and upgrade all packages.
  • Install the guest additions
  • On some Debian based distros, remove persistent-net.rules.

This should give you a working machine, but we’re not done yet. You still need to make the hard disk multi-attachable.

If you where to use this image in Pallet, you could only use it once. Multiattach means that every time a machine is made, a new copy-on-write image is created so the original stays intact.

To do this, delete the VM, but not the vdi file, and run the following command:

VBoxManage modifyhd the/disk.vdi --type multiattach

Finally, you need to create a meta file with the same name as the disk image, but with the .meta extension. As an example:

 {:os-type-id "Ubuntu_64",
  :sudo-password "vmfest",
  :no-sudo false,
  :username "vmfest",
  :os-family :ubuntu,
  :os-version "12.04",
  :os-64-bit true,
  :password "vmfest",
  :description "Ubuntu 12.04 (64bit)"
  :packager :apt}
