I could not figure out how to set swap on existing flavor fast enough,
so I initially edited nova db directly. There were no side effects in
doing so in Icehouse. I see no reason it would not work in Liberty.

For a "nicer" way I ended up recreating flavor I needed to edit:
delete old one, create new one with the same id and swap enabled. I
hope there is a better way, but editing db directly, or recreating
flavor was sufficient for me so far.
