h1. Openstack Installation TTNN

h2. Pending upstream fixes:

* build-debian-openstack-images, changes should be in next package version:

** Fix extlinux installation on jessie: http://anonscm.debian.org/cgit/openstack/openstack-debian-images.git/commit/?id=1a4ddceb99fb66f42f79e87a183d8e96952e5ac3

** Fix cloud-init setup with configdrive: http://anonscm.debian.org/cgit/openstack/openstack-debian-images.git/commit/?id=15cce87e2fa15b8952d69fb58711bfa88b21ef87

** Use Configdrive first for cloud-init: http://anonscm.debian.org/cgit/openstack/openstack-debian-images.git/commit/?id=1b1e1093d5ee525426382ad29b8219ab58f6656d

* nova: 

** Fix live-migration avec ceph and configdrive:: https://review.openstack.org/#/c/112014/, si la solution est mergé upstream, j'appliquerai le patch au package debian

h2. Installation

Le setup installé est composé de :

* 3 hyperviseurs (compute node) qui contiendront 1 ceph-mon, N ceph-osd, nova-compute (qui lance les VM), neutron-openvswitch-agent (qui configure le réseau des vms)

* 1 VM (controler node), qui contient tous les services de management d'openstack (nova, cinder, glance, neutron)

Les étapes d'installation sont les suivantes:

* Préparation manuelle de la VM de management sur un des hyperviseurs

* Installation de ceph et openstack sur toutes les machines avec puppet

* Déplacement de la VM de management d'openstack dans openstack.

h3. Preparation de la VM de management, le controlleur

h4. Préparation du réseau

<pre>

h4. Installation de la VM

<pre>

$ virt-install --name openstack --ram 2048 --network bridge=br-net --nographics --serial pty --wait -1 --noreboot --autostart --disk /openstack.raw,bus=virtio,cache=none,io=native --import

$ EDITOR="sed -i -e \"s,<source bridge='br-net'/>,<source bridge='br-net'/><virtualport type='openvswitch' />,g\"" virsh edit openstack  # Openvswitch is not yet supported by virt-install

$ virsh  start openstack

$ ssh root@openstack.tetaneutral.net -p 2222

</pre>

Une fois connecté à la VM:

<pre>

$ apt-get install puppet

$ puppet agent --enable

$ puppet agent -vt --server puppet.tetaneutral.net --certname openstack.tetaneutral.net --pluginsync
