Installation High-Level Overview - Virtual Deployment
=====================================================
The VM nodes deployment operates almost the same way as the bare metal
deployment with a few differences. ``opnfv-deploy`` still deploys an
undercloud VM. In addition to the undercloud VM a collection of VMs
(3 control nodes + 2 compute for an HA deployment or 1 control node and 1
or more compute nodes for a non-HA Deployment) will be defined for the target
OPNFV deployment. The part of the toolchain that executes IPMI power
instructions calls into libvirt instead of the IPMI interfaces on baremetal
servers to operate the power managment. These VMs are then provisioned with
the same disk images and configuration that baremetal would be. To Triple-O
these nodes look like they have just built and registered the same way as bare
metal nodes, the main difference is the use of a libvirt driver for the power
management. Finally, the default network_settings file will deploy without
modification. Customizations are welcome but not needed if a generic set of
network_settings are acceptable.
Installation Guide - Virtual Deployment
=======================================
This section goes step-by-step on how to correctly install and provision the
OPNFV target system to VM nodes.
Install Jumphost
----------------
Follow the instructions in the `Install Bare Metal Jumphost`_ section.
Running ``opnfv-deploy``
------------------------
You are now ready to deploy OPNFV!
``opnfv-deploy`` has virtual deployment capability that includes all of
the configuration nessesary to deploy OPNFV with no modifications.
If no modifications are made to the included configurations the target
environment will deploy with the following architecture:
- 1 undercloud VM
- The option of 3 control and 2 or more compute VMs (HA Deploy / default)
or 1 control and 1 or more compute VM (Non-HA deploy / pass -n)
- 1-5 networks: provisioning, private tenant networking, external, storage
and internal API. The API, storage and tenant networking networks can be
collapsed onto the provisioning network.
Follow the steps below to execute:
1. ``sudo opnfv-deploy -v [ --virtual-computes n ]
[ --virtual-cpus n ] [ --virtual-ram n ] [ --flat ]
-n network_settings.yaml -i inventory.yaml -d deploy_settings.yaml``
2. It will take approximately 45 minutes to an hour to stand up undercloud,
define the target virtual machines, configure the deployment and execute
the deployment. You will notice different outputs in your shell.
3. When the deployment is complete the IP for the undercloud and a url for the
OpenStack dashboard will be displayed
Verifying the Setup - VMs
-------------------------
To verify the set you can follow the instructions in the `Verifying the Setup`_
section.
