Gavin's notes on getting gitian builds up and running using KVM:

These instructions distilled from:
... see there for complete details.

You need the right hardware: you need a 64-bit-capable CPU with hardware virtualization support (Intel VT-x or AMD-V). Not all modern CPUs support hardware virtualization.

You probably need to enable hardware virtualization in your machine's BIOS.

You need to be running a recent version of 64-bit-Ubuntu, and you need to install several prerequisites:
sudo apt-get install ruby apache2 git apt-cacher-ng python-vm-builder qemu-kvm

Sanity checks:
sudo service apt-cacher-ng status # Should return apt-cacher-ng is running
ls -l /dev/kvm # Should show a /dev/kvm device

Once you've got the right hardware and software:

git clone git://
git clone git://
mkdir gitian-builder/inputs
cd gitian-builder/inputs
# Inputs for Linux and Win32:
wget -O miniupnpc-1.6.tar.gz ''
wget ''
# Inputs for Win32: (Linux has packages for these)
wget ''
wget ''
wget ''
wget ''
wget ''
wget ''
cd ../..

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

# Build Linux release:
cd bitcoin
git pull
cd ../gitian-builder
git pull
./bin/gbuild --commit bitcoin=HEAD ../bitcoin/contrib/gitian-descriptors/gitian.yml

# Build Win32 dependencies: (only needs to be done once, or when dependency versions change)
./bin/gbuild --commit bitcoin=HEAD ../bitcoin/contrib/gitian-descriptors/boost-win32.yml
./bin/gbuild --commit bitcoin=HEAD ../bitcoin/contrib/gitian-descriptors/deps-win32.yml
./bin/gbuild --commit bitcoin=HEAD ../bitcoin/contrib/gitian-descriptors/qt-win32.yml

# Build Win32 release:
./bin/gbuild --commit bitcoin=HEAD ../bitcoin/contrib/gitian-descriptors/gitian-win32.yml


gitian-builder now also supports building using LXC. See
... for how to get LXC up and running under Ubuntu.

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.

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

1. Download and install VirtualBox from

2. Download the 64-bit Ubuntu Desktop 12.04 LTS .iso CD image from

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 20 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 "Once you've got the right
hardware and software" instructions above:
export USE_LXC=1
git clone git://
... etc
