<p class="MsoNormal">Here is the aggregated summary from Cyborg vPTG discussion. Please check it out and feel free to feedback any concerns you might have.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">We did a retrospective of Wallaby release, including:<o:p></o:p></p>
<p class="MsoNormal"> * We supports more operations supported for a VM with accelerator attached.<o:p></o:p></p>
<p class="MsoNormal"> * We introduced new drivers for Intel x710 NIC and Inspur’s NVMe SSD Card.<o:p></o:p></p>
<p class="MsoNormal"> * We implemented a new configuration file allowing more flexible device configuration.<o:p></o:p></p>
<p class="MsoNormal"><span style="font-family:"Times New Roman",serif"> </span><o:p></o:p></p>
<p class="MsoNormal">Topic discussion:<o:p></o:p></p>
<p class="MsoNormal"> Here's some major discussion and conclusion of Cyborg vPTG. For more details, please refer to the etherpad[1].<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal"> * More nova operation supporting: <o:p></o:p></p>
<p class="MsoNormal"> - We prioritized the tasks: 1. suspend/resume. 2. cold migration. 3. live migration.
<o:p></o:p></p>
<p class="MsoNormal"> * vGPU support:<o:p></o:p></p>
<p class="MsoNormal"> - We reached an internal agreement on whole workflow which can be apply as a generic framework for mdev device.<o:p></o:p></p>
<p class="MsoNormal"> * API enhancement:<o:p></o:p></p>
<p class="MsoNormal"> Some of the following items requires a new micro-version.
<o:p></o:p></p>
<p class="MsoNormal"> - Add refresh policy check for all APIs.<o:p></o:p></p>
<p class="MsoNormal"> - Add device profile update API.<o:p></o:p></p>
<p class="MsoNormal"> - Add ARQ query by multiple instances API.<o:p></o:p></p>
<p class="MsoNormal"> - Add disable/enable device API, this one requires a spec first.
<o:p></o:p></p>
<p class="MsoNormal"> - Enhance device profile show API with more information.<o:p></o:p></p>
<p class="MsoNormal"> * Cleanup issue:<o:p></o:p></p>
<p class="MsoNormal"> - This issue comes from the case where one compute node shutdown accidently, and the accelerator records<o:p></o:p></p>
<p class="MsoNormal"> in placement and cyborg DB remains as the orphaned resources. We agreed to implement a mechanism to clean<o:p></o:p></p>
<p class="MsoNormal"> up the orphaned resources, this one also need a spec.<o:p></o:p></p>
