Setting up Gitian on a VM using LXC

If your main machine is a 64-bit Mac or PC with a few gigabytes of memory and at least 10 gigabytes of free disk space, you can gitian-build using LXC running inside a virtual machine (VirtualBox, VMware, probably others too).

Here's a description of Gavin's setup on OSX 10.6:

  1. Download and install VirtualBox from https://www.virtualbox.org/

  2. Download the 64-bit Ubuntu Desktop 12.04 LTS .iso CD image from http://www.ubuntu.com/

  3. Run VirtualBox and create a new virtual machine, using the Ubuntu .iso (see the VirtualBox documentation for details). Create it with at least 2 gigabytes of memory and a disk that is at least 50 gigabytes big.

  4. Inside the running Ubuntu desktop, install:

    sudo apt-get install debootstrap lxc ruby apache2 git apt-cacher-ng python-vm-builder

  5. Still inside Ubuntu, tell gitian-builder to use LXC, then follow the instructions below:

    export USE_LXC=1

Sanity check:

sudo service apt-cacher-ng status  # Should return apt-cacher-ng is running

Enable bridging interface for networking:

sudo brctl addbr br0
sudo ifconfig br0 10.0.2.2/24 up

Once you've got the right hardware and software:

git clone git://github.com/dogecoin/dogecoin.git
git clone git://github.com/devrandom/gitian-builder.git

Prepare the builder VMs:

cd gitian-builder
bin/make-base-vm --lxc --suite precise --arch i386
bin/make-base-vm --lxc --suite precise --arch amd64
cd ..

Now follow the build process under doc/release-process to first build the dependecies (one time task, or when the dependencies change) and then the client packages.
