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=10.20.0.0/16 \ --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=10.20.0.0/16. /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
