Funny coincidence because I was just triaging this nova bug this morning:

https://bugs.launchpad.net/nova/+bug/1821755

And referenced the starlingx fix for it in there, but now I've also 
duplicated it against the old bug linked in the spreadsheet. I did leave 
some comments in the bug that are likely limitations in the starlingx 
solution which work for starlingx when you have 1-2 nodes in an edge 
site with 1-2 nova-conductor services, but likely wouldn't be sufficient 
in a large public cloud with nova-conductor services spread across 
multiple hosts (unless some distributed lock manager is being used, 
which I don't think oslo.concurrency supports under the covers does it?).

Skimming the other items in the spreadsheet they mostly look like 
already in-progress items upstream, are planned for discussion at the 
PTG, or are related to server groups (which is a known haven for race 
issues since we don't model affinity in placement yet).

Thanks for the update and transparency here.
