Des images valent mieux qu'un grand discours :






_PS_: Tiré de la FAQ de HP :


        What is a seed?

A seed VM is a bootable KVM VM image provided as part of HP Helion 
OpenStack and is deployed in a VM instance. This image contains the 
minimum services required of OpenStack to function and to be able to 
provision physical hardware to deploy the undercloud. The services are 
Nova, Neutron, Glance, Keystone, Ironic & Heat.

This is the first phase of the HP Helion OpenStack installation.


        What is the undercloud?

The undercloud server is a basic single-node OpenStack installation 
running on a single physical server used to deploy, test, manage, and 
update the overcloud servers. There is no HA configuration for the 
undercloud.

It contains a strictly limited sub-set of OpenStack, just enough to 
interact with the overcloud. The services running on the undercloud are 
Nova, Neutron, Glance, Keystone, Ironic, Heat, Horizon & Ceilometer. 
This server also contains HP Helion content distribution catalog 
service, which provides a mechanism to download and install content and 
updates for the overcloud.

The undercloud also hosts images for various server types which will 
form the functional cloud environment - the overcloud. These images are 
overcloud Controller, overcloud Compute, overcloud Swift & overcloud 
Compute Proxy (required for clouds that support VMWare ESX as a hypervisor).

This is the second phase of the HP Helion OpenStack installation.


        What is the overcloud?

The overcloud is the functional cloud available to run guest virtual 
machines and workloads. It offers access to the Nova, Neutron, Glance, 
Keystone, Cinder, Swift, Ironic, Heat, Horizon, and Ceilometer services.

Setting up the overcloud completes the overall Helion OpenStack 
installation process.
