What's new in version 2.0.2

IBM® Power® Virtualization Center version 2.0.2 comes with many new features and enhancements. We are more than delighted to listen to our client requirements and implement the same along with our benchmark innovation strategies that take PowerVC to the next level every release.

PowerVC high availability and scale architecture

Earlier versions of PowerVC followed the All-in-One (AIO) deployment model that involved installing packages and setting up services corresponding to stateless (OpenStack based services like nova, cinder, etc.) and stateful services (MariaDB, RabbitMQetc) on a single system; thus, not following the distributed approach that OpenStack supports. While All-in-one deployment model keeps PowerVC deployment simple and highly manageable, the model denies PowerVC the scale and high availability that it might achieve with a multinode model. For details, see PowerVC high availability and scale architecture.

PowerVC support for P10

PowerVC version 2.0.2 supports managing a Power E1080 host via HMC or NovaLink.

Functional enhancements

PowerVC updates

Listed below are the key features implemented in the release.

Direct install or upgrade to
You can now directly install PowerVC unlike earlier releases where you had to first install the major version and then update to the available fix pack version of PowerVC. Similarly, if you have any previous version of PowerVC 2.0.x installed, take a backup, copy the backup file to a custom location, and then uninstall the existing version. Reboot the system and install or upgrade to PowerVC
Backup and restore on multinode
With PowerVC, you can perform restore directly on multinode (three nodes) from PowerVC version 2.0.1 to For details, see Upgrading to PowerVC 2.0.2 or
HMC host scaling with additional Compute plane node
Starting PowerVC version, Compute plane nodes are introduced to share the compute services load and allow managing more HMC managed hosts. For details, see Compute plane node and HMC host scaling.
Multinode on HMC
HMC managed hosts can be added to both single node setup as well as three node setup of PowerVC cluster. This ensures the Nova compute process for the host is configured in an Active-passive mode and monitored by Pacemaker.
Infoblox integration
You can manage the DNS records in Infoblox through PowerVC GUI. For details, see Automatically update DNS records.
Multinode support on SLES ppc64le
Installation is supported on SLES ppc64le for both single node and multinode environments.
Scheduled tasks

If you are assigned to self-service user role, you can schedule virtual machine operations such as start, stop, and restart of VM(s).

Select network order on GUI (RFE ID: 151694)

You can select the network order while deploying a VM on PowerVC GUI.

Compute plane node management API
The Compute plane node APIs allows you to register, view details, update, or deregister a Compute plane node from PowerVC. For details, see Compute plane node.
Scheduled tasks API
The scheduled tasks APIs can be executed by using curl commands. These APIs can be used for scheduling start, stop, restart, or deploy VMs. You can also choose to fetch list of tasks that are scheduled by users who are assigned to different roles. For details, see Scheduled tasks.

PowerVC version 2.0.2 features

PowerVC multinode (RFE ID: 111561)
  • PowerVC installation through operations manager

    The PowerVC operations manager (OpsMgr) is a collection of utilities and services that are designed to facilitate end-user operation of PowerVC clusters like install, upgrade, backup, and restore. Starting 2.0.2 release, you must install and configure PowerVC operations manager before installing PowerVC. For details, see Initiate installation through PowerVC operations manager.

  • PowerVC cluster management

    With one or more nodes of PowerVC now being deployed to work as a cluster, maintenance operations are handled through the PowerVC operations manager powervc-opsmgr CLI. This command provides you options to install, uninstall, add or replace nodes, and upgrade.

  • HMC

    HMC managed nodes can be used in a three-node PowerVC cluster when setting the hmc_multinode configuration in powervc-config. This ensures the Nova compute process for the host is configured in an Active-passive mode and monitored by Pacemaker. By default, the HMC managed hosts only work on a single node setup of PowerVC version 2.0.2.

  • NovaLink

    NovaLink managed hosts can be added to both one-node PowerVC cluster as well as the three-node PowerVC cluster. The Nova and Neutron agents on NovaLink communicate with the PowerVC by using a virtual IP. This means even if one of the PowerVC nodes is down, the requests will be routed to the appropriate nodes.

Scheduled tasks (RFE ID: 131441)
You can view details of tasks that are scheduled on a virtual machine in the Dashboard > Tasks > Scheduled tasks of the GUI.

If you are assigned to any of these roles - admin, admin_asst, or a vm_manager, you can schedule virtual machine operations such as start, stop, restart and deploy of VM(s). If you are assigned to a deployer role, you can schedule deploy of VM(s).

SR-IOV updates (RFE IDs: 144847, 143130, 148411, 130232)
  • Support for SR-IOV network in deploy template

    Starting PowerVC version 2.0.2, you can create deploy templates with SR-IOV networks. You can deploy virtual machines by using these deploy templates.

  • VIOS selection based on SCG for SR-IOV vNICs
