主题: [cyborg][ptg]Cyborg vPTG Summary April 2021



Hi all,



Please ignore my previous message, it is sent to wrong person. Sorry about this.



Thanks for all your participation! We’ve conducted a successful meeting last week.



Here is the aggregated summary from Cyborg vPTG discussion. Please check it out and feel free to feedback any concerns you might have.



We did a retrospective of Wallaby release, including:

    * We supports more operations supported for a VM with accelerator attached.

    * We introduced new drivers for Intel x710 NIC and Inspur’s NVMe SSD Card.

    * We implemented a new configuration file allowing more flexible device configuration.



Topic discussion:

    Here's some major discussion and conclusion of Cyborg vPTG. For more details, please refer to the etherpad[1].



   * More nova operation supporting:

           - We prioritized the tasks: 1. suspend/resume. 2. cold migration. 3. live migration.

   * vGPU support:

           - We reached an internal agreement on whole workflow which can be apply as a generic framework for mdev device.

   * API enhancement:

           Some of the following items requires a new micro-version.

           -  Add refresh policy check for all APIs.

           -  Add device profile update API.

          - Add ARQ query by multiple instances API.

           -  Add disable/enable device API, this one requires a spec first.

           -  Enhance device profile show API with more information.

   * Cleanup issue:

           - This issue comes from the case where one compute node shutdown accidently, and the accelerator records

           in placement and cyborg DB remains as the orphaned resources. We agreed to implement a mechanism to clean

           up the orphaned resources, this one also need a spec.
