This needs todo more than just create the config. You need to use the libvirt PCI APIs to validate that it is safe to assign the devices requested, and track which devices are given to which guest, to avoid concurrent assignemnt to 2 guests. Basically I'd expect this to borrow all the code currently in the QMEU driver related to the 'activePciHostdevs' and 'inactivePciHostdevs' data structures.
Right. Chunyan already posted such a patch series [1], but Laine noted that it would be useful to maintain the state of PCI device assignment for coordination among multiple drivers. Chunyan posted a design [2] for a "hostdev passthrough driver", and IIRC she has started coding after receiving feedback from the list.
I see that Chunyan has now posted patches for this work

Could you can help review and test those?
Sure, will look at it tomorrow. -- Best Regards, Marek Marczykowski Invisible Things Lab
