I've been working on moving changes from qemu_command to qemu_domain as part of a validate the controller def sequence of calls... v3 is here: https://www.redhat.com/archives/libvir-list/2017-December/msg00209.html Do you mind if I merge that series before I post v4? John

Funny made sense when my brain told my fingers what to type, but they seem to have their own problems ;-)... So let's try again... I'm working on a series that's moving a bunch of the qemu_command controller validation checks into qemu_domain. So my question is, do you mind if I merge this one patch into what I have built up for the next posting of that series. One way or another one of us was going to have to merge, I just figured I could get in front of that bus. John

Sure, feel free to pick up the patch and merge it along with the rest of your work. I'll rebase the remaining patches afterwards. -- Andrea Bolognani / Red Hat / Virtualization
The input configurations set all existing options for all PCI controllers, to see what ends up sticking in the output.
