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.

Thanks,

Xin-Ran Wang
