12. 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.

13. Installation Guide - Virtual Deployment

This section goes step-by-step on how to correctly install and provision the OPNFV target system to VM nodes.

13.1. Install Jumphost

Follow the instructions in the Install Bare Metal Jumphost section.

13.2. 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

13.3. Verifying the Setup - VMs

To verify the set you can follow the instructions in the Verifying the Setup section.
