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

These instructions distilled from: https://help.ubuntu.com/community/KVM/Installation ... 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://github.com/IParn/limecoin.git
git clone git://github.com/devrandom/gitian-builder.git
mkdir gitian-builder/inputs
cd gitian-builder/inputs
# Inputs for Linux and Win32:

cd gitian-builder

cd ..

# Build Linux release:

git pull
cd ../gitian-builder
git pull
sudo ./bin/gbuild --commit limecoin=HEAD ../limecoin/contrib/gitian-descriptors/gitian.yml

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

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

gitian-builder now also supports building using LXC. See https://help.ubuntu.com/12.04/serverguide/lxc.html ... 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 ... etc

FAQ:

ssh: connect to host localhost port 2223: Connection refused This means that qemu has failed to start. Try editing libexec/start-target and changing "kvm" to "qemu". If that fails, look in var/target.log for any error messages. Another reason may be that you are using a VPS , try installing Ubuntu and gitian in a Desktop Computer.(Works for me)

Connection timed out during banner exchange This means your qemu VM didn't manage to boot far enough for ssh to be running. There appears to be a lurking bug in some python-vm-builder versions that causes bootloader installation to fail.

cp: cannot open `base-lucid-i386.qcow2' for reading: Permission denied Code: sudo chmod 644 base-lucid-i386.qcow2

Updating apt-get repository (log in var/install.log) root@localhost's password: ubuntu@localhost's password:

Delete all your VMs, and reinstall them Clean. ( I had this problem as well when I was compiling using gitian. I'm confident theres a better solution but restarting the vm instance that I was running kvm in solved the issue. Likely something to do with residuals left from the previous dependency builds that werent removed correctly wjem they completed.

I stopped digging after the reboot solved the issue.)
