[nova][ptg] PCI refactoring needs and a strawman proposal inside
Based on some Forum discussions, we had a de facto conversation at the Nova PTG about any potential things we could do for helping our operators, but also potentially Cyborg since they use the PCI passthrough capabilities. The feedback from ops (thanks mnaser) was that PCI passthrough works pretty smoothly but there are some ugly issues where we could improve the UX. The agreement in the room was, at least for Ussuri, to start collecting some ideas on how we could model Placement usage for PCI devices and also write motivations for such things in a spec. We also agreed on a smooth upgrade plan where PCITracker would still be present for a couple of releases until we're able to close the feature gap. Bauzas volunteered for drafting the spec and gibi, stephenfin and bauzas started to sketch up the Placement modeling on a whiteboard, picture to be shared in a follow-up.

i have a list of things i want to enhance related to pci/sriov so i would be interested in this topic too. it might be worth consiering a SIG on this topic if it will be cross project.

/me too I have a bunch of work to do with device pass-through that may, or may not be on the PCI bus so I'd like to ensure we don't make my use case impossible ;P Yours Tony.
