tl;dr If you care about NUMA live migration, check out [1] and test in in your env(s), or review it. Over the months that I've worked on NUMA LM, I've been pinged by various folks that were interested in helping out. At this point I've addressed all the issues that were found at the end of the Stein cycle, and the series is ready for review and testing, with the aim of getting it merged in Train (for real this time). So if you care about NUMA-aware live migration and have some spare time and hardware (if you're in the former category I don't think I need to explain what kind of hardware - though I'll try to answer questions as best I can), I would greatly appreciate it if you deployed the patches and tested them. I've done that myself, of course, but, as at the end of Stein, I'm sure there are edge cases that I didn't think of (though I'm selfishly hoping that there aren't). I believe the series is also ready for review, though I haven't put it in the runway queue just yet because the last functional test patch is still a WIP, as I need to fiddle with it to assert more things. Thanks in advance, cheers! [1] https://review.opendev.org/#/c/672595/8
