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
2011-10-25 18:27:09 +02:00
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://github.com/bitcoin/bitcoin.git
git clone git://github.com/devrandom/gitian-builder.git
mkdir gitian-builder/inputs
