A Virtual Machine for Python Related Development on Gentoo

Introduction

This project automates the setup of a development environment for python related development on gentoo which I prefered. You can customized the Vagrantfile on your fork. This is the easiest way to build a box with everything ready to start hacking, all in an isolated virtual machine.

Requirements

How To Build The Virtual Machine

1. Download the .box file from here which I prepared at first. It's about 0.96G.

➜  boxes  wget http://dl.dropbox.com/u/1212791/everbird-gentoo-64-i686-3.3.8.box

2. Add it to vagrant boxes:

➜  boxes  vagrant box add everbird-gentoo-64-i686-3.3.8 everbird-gentoo-64-i686-3.3.8.box
[vagrant] Downloading with Vagrant::Downloaders::File...
[vagrant] Copying box to temporary location...
[vagrant] Extracting box...
[vagrant] Verifying box...
[vagrant] Cleaning up downloaded box... 
➜  boxes  vagrant box list
everbird-gentoo-64-i686-3.3.8

3. Build the virtual machine:

➜  vagrant  git clone --recursive git://github.com/everbird/vagrant-cidar.git

➜  vagrant  cd vagrant-cidar
➜  vagrant-cidar git:(master) vagrant up

That's it.

The setup itself takes about 11-13 minutes in my MacBook Pro.

After the installation has finished, you can access the virtual machine with

➜  vagrant-cidar git:(master) vagrant ssh
Last login: Sat Sep  1 17:20:18 CST 2012 from 10.0.2.2 on ssh
    Remember, there are not stupid questions, just stupid people.
                                        - Herbert Garrison
vagrant@cidar ~ $ 

Port 2223 in the host computer is forwarded to port 22 in the virtual machine. Ip of the vm was set to 10.0.3.20. You can ssh to vm either way.

As we use NFS Shared Folders by default, vagrant need authorization to change /etc/exports to mount. A better way is grant vagrant sudo-access without password for NFS-setup. A handy script is available here.

Virtual Machine Management

When done just log out with ^D and suspend the virtual machine

host $ vagrant suspend

then, resume to hack again

host $ vagrant resume

Run

host $ vagrant halt

to shutdown the virtual machine, and

host $ vagrant up

to boot it again.

You can find out the state of a virtual machine anytime by invoking

host $ vagrant status

Finally, to completely wipe the virtual machine from the disk destroying all its contents:

host $ vagrant destroy # DANGER: all is gone

Please check the Vagrant documentation for more information on Vagrant.
