10. Installation High-Level Overview - Virtual Deployment

The VM nodes deployment operates almost the same way as the bare metal deploymen t with a few differences. opnfv-deploy still deploys an Instack VM. In addition to t he Instack VM a collection of VMs (3 control nodes + 2 compute for an HA deployment or 1 contr ol node and 1 compute node for a Non-HA Deployment) will be defined for the target OPNFV dep loyment. The part of the toolchain that executes IPMI power instructions calls into libvi rt 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 RDO Manager these nodes look like they have just built and registered the sam e way as bare metal nodes, the main difference is the use of a libvirt driver for the pow er management.

11. Installation Guide - Virtual Deployment

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

11.1. Install Jumphost

Follow the instructions in the Install Bare Metal Jumphost section.

11.2. 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 Instack VM
  • The option of 3 control and 2 compute VMs (HA Deploy / default) or 1 control and 1 compute VM (Non-HA deploy / pass -n)
  • 2 networks, one for provisioning, internal API, storage and tenant networking traffic and a second for the external network

Follow the steps below to execute:

  1. sudo opnfv-deploy --virtual [ --no-ha ]
  2. It will take approximately 30 minutes to stand up instack, 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 you will see “Overcloud Deployed”

11.3. Verifying the Setup - VMs

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

Before you get started following these instructions you will need to add IP addresses on the networks that have been created for the External and provisioning networks. By default the External network is 192.168.37.0/24 and the provisioning network is 192.0.2.0/24. To access these networks simply add an IP to brbm and brbm1 and set their link to up. This will provide a route from the hypervisor into the virtual networks acting as OpenStack’s underlay network in the virtual deployment.

ip addr add 192.0.2.252/24 dev brbm
ip link set up dev brbm
ip addr add 192.168.37.252/24 dev brbm1
ip link set up dev brbm1

Once these IP addresses are assigned and the links are up the gateways on the overcloud’s networks should be pingable and read to be SSHed to.

ping 192.0.2.1
ping 192.168.37.1

Now continue with the Verifying the Setup section.
