It’s finally here – the latest release of PowerVC, which we have been hard at work on for the past several months. This release fully supports our previous technical previews to give you one totally integrated software-defined infrastructure. We now allow you to manage OpenPOWER systems, export and import images more easily than ever, and even gave the user interface an update. On PowerVC Cloud edition, you can try out our Database as a Service technical preview. Read on for full details about the major updates:

  • Database as a Service technical preview (Cloud edition only)
  • Database as a Service (DBaaS) refers to database instances that are deployed in a cloud, where the user does not need to configure or maintain the database instance or its environment, and can access and use the database just like any other service. PowerVC uses the OpenStack Trove component to deliver these capabilities.

  • Integrated software-defined storage
  • Software-defined storage (converged infrastructure) was previously a technical preview. This support is now included in the official product release. On systems managed by PowerVM® NovaLink, you can use software-defined storage (SDS). SDS requires the software-defined networking (SDN) capability. Together, these two technologies allow administrators to have a predefined node type that has network, storage, and compute all within the server. Then as you increase the number of servers in your environment, the infrastructure elastically and automatically grows.

  • Support of OpenPOWER and other systems running KVM on Power
  • PowerVC now supports KVM on Power running Ubuntu 16.04. KVM based systems, such as OpenPOWER, can be managed from the same installation of PowerVC that is managing existing PowerVM infrastructure. This support builds on the software-defined networking and the new software-defined storage features.

  • Import and export images
  • You can export and import the deployable images between managed storage providers and between data centers from the PowerVC user interface. Use the powervc-image command to import images into PowerVC from outside the managed SAN and export images to a local path in the OVA packaged format.

  • Use SAN-backed clusters
  • When using software-defined storage, you can now use either SAN-backed or local disk-backed clusters. Each cluster must be made up of the same types of nodes. That is, all disks must be SAN-backed or all disks must be local disk-backed within each cluster.

  • Specify multiple IP address ranges and edit IP address ranges
  • When adding or editing a network, you can now specify multiple IP address ranges. Additionally, you can edit the IP address ranges of existing networks.

  • Create and attach multiple volumes
  • You can now create or attach multiple volumes at the same time.

  • Flexible SAN zone names
  • PowerVC provides a template format that allows you to customize SAN zone names.

  • Capture a live virtual machine
  • You can now capture running workloads to avoid disruptions in your environment.

  • Additional project quotas
  • These new quotas are supported for projects: Volume Backup (GB), Volume Backups, and Volume Groups.

  • Set the Physical Page Table (PPT) ratio
  • The PPT ratio controls the size of the page table that is used by the hypervisor when performing live partition migration. The larger the PPT, the more entries are available for use by the partition for mapping virtual addresses to physical real addresses. If the PPT is set too small and the partition is running workloads, performance in the partition can decline during live partition migration.
    You can set the PPT ratio on a compute template; either in the user interface or by using the Flavors API. This setting is particularly useful for those running SAP HANA workloads.

  • User interface updates
  • Along with a new look and feel, some items on the user interface have been moved, renamed, or have different behaviors:

    • Links to fabrics and networks have been removed from the Home page.
    • The Import button on the Images page has been renamed Create.
    • The Verify environment button has been moved to a new tab on the Home page called Environment Checker. This tab also displays the results of the most recent results of the check.
    • The Configuration page has been reorganized.
    • The IP Addresses tab on the Network page shows only addresses that are locked or in use.
    • The storage count in the navigation pane indicates the number of registered storage providers instead of volumes.

You can read the official announcement here.

  1. Hi it’s exciting new developments in new version. Any chance of also including creating of Hyperswap volumes when using SVC as Storage target?

    • Unfortunately, the Storwize driver does not yet have that enhancement but it is under consideration for inclusion in a future Openstack release.

  2. Is our request for enhancement to PowerVC 1.3.3 included? The details are in the URL shown below.
    Request ID 108803 Enhance Zoning Algorithm in PowerVC to prevent ISL hops

    • Joe Cropper October 13, 2017

      Greetings! Unfortunately, that enhancement didn’t make it into this release – but, we’ll consider it for a future release. A number of other RFEs did make it in, however, which we’ll mark as implemented when the release goes live! Thanks again for the suggestion – we’re always looking to include RFEs to make the product better.

  3. Hi. Does PowerVC support EMC Vipr with PowerVC 1.4.0?

  4. Hi Anyn chance to support muliple VIOS and allow me to select specific VIOS for customers who for example dedicate 2 VIOS to the network and 2 VIOS to the SAN.

  5. Sridhar Venkat November 01, 2017

    Lilian, yes you can. Create shared ethernet adapter on specific VIOS and pick it while creating a Network in PowerVC. Similarly, pick specific VIOS while creating storage connectivity group in PowerVC. Use such a network and storage connectivity group while deploying VMs.

  6. Is there a way to request NIM directly from PowerVC ?

  7. Thiago Girolamo November 23, 2017

    Tha GCA machines are supported?

    • Hello,
      Thank you for your question. Could you please explain what you mean by “GCA machines”? Thanks!

      • Thiago Girolamo November 27, 2017

        Hi! thanks for your response. 8335-GCA (S822LC for commercial computing)

        • Ah! Then yes, you’d be able to manage it with the new KVM on Power support in 1.4.0.

          • Thiago Girolamo November 28, 2017

            but the configurator (e-config) does not let me add the PowerVC. Any tips?

          • It is not supported in releases prior to 1.4.0. Are you working on a 1.4.0 beta system?

  8. I am in process of setup new PowerVC 1.3.3 Version.
    Does it support for existing zoning configuration brocade SAN switches? when try to add fabric switch with existing zoning mange virtual machines giving errors not able to add into powerVC.
    I have already setup two power8 servers with 15 LPARs in production up and running. currently its capable of doing LPM from HMC.

    • Carl_Pecinovsky December 12, 2017

      Hi kiran. Yes, PowerVC supports managing Brocade SAN switches. And yes, it supports managing existing VMs that have been setup outside of powervc, provided you have the switch fabric(s) managed and the storage provider(s) managed. PowerVC does not “manage” the existing zoning configuration. It assumes the VM is zoned and has access to its storage. It does not need to modify zones unless you later choose to attach volumes through PowerVC using a new connectivity type (e.g. vSCSI vs. NPIV).

      So, currently you are getting an error trying to manage an existing VM. (1) Ensure the switch is managed. (2) Ensure the storage where the VM gets its volume(s) from is managed. It’s disks must come from supported storage providers for PowerVC to be able to manage. (3) The networking also needs to be a supported configuration. The manage process will attempt to create a matching network if you don’t have one defined already. If you still see an error, then the actual error message and logged error messages on the PowerVC server will be important.

  9. Hi Carl_Pecinovsky,
    Thank you for your reply.

    Yes, I have added the HMC connection and P8 Servers hosts using Power VM.

    1) Ensured SAN switches is Managed.
    2) Ensured Storage is managed. (the Hitachi Storage volumes are connected to VM through vSCSI adapters) I have added volumes to PowerVC.
    3) I have added the Networking with required VLAN IDs.
    When I scan for VMs from Managed hosts I able to see all the LPAR VMs.( But when request to manage VM getting error PD-B000013 VM are not candidates for management because mappings for attached volumes could not found on the storage providers first make sure Storage providers and Fabrics for this VM are added to PowerVC. )
    As i told I Ensured SAN volume mapped from storage provider and SAN Switches. Very strange error.
    Is it these volumes should be mapped to SAN zoning for PowerVC host?

    Thanks in advance..

    • Carl_Pecinovsky January 03, 2018

      So presumably the Hitachi volume driver is not able to lookup volumes on the hitachi array using the attachment information provided to it. You should open a PMR to have the cause investigated. The development team would need to have DEBUG logging enabled on the volume-.log during the management attempt to be able to investigate further why it is not able to correlate the VM’s volumes with the array they should be hosted on. Thanks.

  10. Thank you Carl_Prcinovsky, I have open the PMR ..

  11. Hi All,
    just installed powervc version 1.4.0 but unable to startup powervc-bumblebee.service. PowerVC Bumblebee status show as Active: failed (Result: exit-code). this regardless i noticed powervc page opens but still cant login, error shows “Invalid login attempt: An error has occurred: 500 (Internal Server Error)”.

    Does anyone have information on how i can resolve this errors and get powervc working??​ pls share.

  13. Hello All,

    Unfortunately, I have deleted the Information Messages on PowerVC GUI . Please help me how can i recover them. I’m also not sure if there is a PowerVC backup in place.


    • Imran Kazi May 24, 2018

      Hi Chandu,
      Unfortunately there is no way to recover the message once deleted from PowerVC UI, unless you are taking regular backup of PowerVC. In case you are not sure if you have taken backup for your PowerVC, please check this folder where backups are stored by default “/var/opt/ibm/powervc/backups/”, if you see folders starting with 20180524*** (starting with dates YYYYMMDD) here, you will see “powervc_backup.tar.gz” file under those folders which you can restore. In case you have taken backup with customize path search for “powervc_backup.tar.gz” file on your filesystem.

      Please refer below link on how to take PowerVC backup and do restore from your backups


      • Hello Imran,

        Thank you for your response . To do a regular backup ; we just execute the below command

        powervc-backup –noprompt

        once the backup operation s completed ; the file will stored in “/var/opt/ibm/powervc/backups/” ?

        Also, could you please tell me the backup approximate time ? can we find how much space would backup required? are there any other approaches to take the backup other than local system.
