Installing OpenStack Folsom on Debian GNU/Linux wheezy

Installing and testing OpenStack Folsom on a virgin Debian GNU/Linux wheezy takes less than one hour. A set of packages is archived to make sure it keeps working. After checking the pre-requisites such as a public and private interface, the packages are installed and debconf questions answered as instructed.
The networks must then be created with

nova-manage network create private --fixed_range_v4= \
  --network_size=256 --num_networks=2 --vlan=100

/etc/nova/nova.conf is updated to set vlan_interface=dummy0, public_interface=eth0 and fixed_range= /etc/nova/nova-compute.conf is updated to use LibvirtBridgeDriver and an instance can be booted with:

nova boot --poll --flavor m1.tiny --image cirrOS-0.3.0-x86_64 \
  --key_name loic test

gerrit with jenkins : installation and configuration

The review and project management for Git based projects is installed on a virgin Debian GNU/Linux wheezy. Developers of l2mesh must submit patchs to the git repository to gerrit:

remote: Processing changes: new: 1, done
To ssh://loic@gerrit.the.re:29418/l2mesh
 * [new branch]      HEAD -> refs/publish/master/master

Gerrit is bound to jenkins : it will run tests on the patch to be reviewed and let gerrit know if it succeeds. If a developer reviews the patch positively, it can be merged into the repository.
