Mirage Virtualbox VMs via Vagrant

Setup

Clone this repo

$ git clone https://github.com/mirage/mirage-vagrant-vms.git
$ cd mirage-vagrant-vms

This currently contains support for Ubuntu 14.04 LTS ("Trusty Tahr"), Ubuntu 14.10 ("Utopic Unicorn"), Debian 7.8.0 ("wheezy") and Citrix XenServer 6.5.0.

XenServer support imported from https://github.com/jonludlam/packer-xenserver.

Install Virtualbox

First, install Oracle's Virtualbox. Download the appropriate installer for your platform from https://www.virtualbox.org/wiki/Downloads and follow the instructions.

Note that you need a reasonably recent version -- at time of writing, 4.3.4 has been observed to fail to build, while 4.3.26 has been observed to work. Reports of other working or failing versions welcome! (Perhaps as pull requests to this file in this repo :)

Install vagrant

Next, install Vagrant. On OSX I use homebrew so I do this as follows:

$ brew tap phinze/cask
$ brew install brew-cask
$ brew cask install vagrant
$ vagrant --version
Vagrant 1.4.3

Install packer

Then, install Packer. Again, using homebrew this becomes:

$ brew tap homebrew/binary
$ brew install packer

Use

Build a new box using packer:

$ make {ubuntu-14.04,ubuntu-14.10,debian-7.8.0,xenserver-6.5.0}-box

Bring it up and provision it using vagrant:

$ make {ubuntu-14.04,ubuntu-14.10,debian-7.8.0,xenserver-6.5.0}-vagrant

Connect to it via ssh:

$ cd {ubuntu-14.04,ubuntu-14.10,debian-7.8.0,xenserver-6.5.0} && vagrant ssh

Finally, within a box, make sure you add ~/bin to your $PATH to use 0install installed binaries (specifically, opam).

Subsequently, vagrant halt will stop the VM (or the usual shutdown -h now when logged into it), vagrant up will restart it, and vagrant ssh to login.

Deprecated

The following networking instructions need to be updated.

Networking

At the risk of this becoming a "general" Xen networking tutorial (as if such a thing were possible)...

         virtualbox

[ dom0       ]    [ mirage-domU ]
[ 100.64.0.2 ]    [ 100.64.0.3  ]
                  [ vifN.0      ]
     |                |
     +---[ xenbr0 ]---+
             |
             |
          [ eth2 ]
             |
             |

Useful commands

On host:

vboxmanage list hostonlyifs
vboxmanage list dhcpservers

On dom0:

sudo xm network-list mort-www

/etc/network/interfaces

network interface configuration. eth0-N, xenbr0

auto xenbr0
iface xenbr0 inet dhcp
      bridge_ports eth2
      bridge_stp off
      bridge_waitport 0
      bridge_fd 0

#VAGRANT-BEGIN
# The contents below are automatically generated by Vagrant. Do not modify.
auto eth1
iface eth1 inet static
      address 172.16.0.2
      netmask 255.255.255.0
#VAGRANT-END

#VAGRANT-BEGIN
# The contents below are automatically generated by Vagrant. Do not modify.
auto eth2
iface eth2 inet static
      address 100.64.0.2     <*>
      netmask 255.255.255.0  <*>
#VAGRANT-END

Lines marked <*> move to the xenbr0 config from the eth2 config, and the eth2 config marked as manual not static. This makes connection from dom0 to mirage-domU work.

/etc/dhcp/dhcpd.conf

DHCP server config. subnets from which addresses should be responded with.

  range 100.64.0.2 100.64.0.254;
