Cory Fields 4452829b10 gitian: quick hack to fix version string in releases 
Release version strings were broken in Gitian by 7522. This is a minimal fix
suitable for 0.15.

After this, we should fix up version handling for good so that gitian packages
the correct string in the release tarball, so that git is not required to get
the tag name.

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

These instructions distilled from https://help.ubuntu.com/community/KVM/Installation.

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://github.com/bitcoin/bitcoin.git
git clone git://github.com/devrandom/gitian-builder.git
mkdir gitian-builder/inputs
cd gitian-builder/inputs

# Create base images
cd gitian-builder
bin/make-base-vm --suite trusty --arch amd64
cd ..

# Get inputs (see doc/release-process.md for exact inputs needed and where to get them)
...

# For further build instructions see doc/release-process.md
...

gitian-builder now also supports building using LXC. See help.ubuntu.com 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 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 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://github.com/bitcoin/bitcoin.git
