It occurred to me maybe this hamburger is a little too cryptic and subtle. Of course it only takes one click to know what's in there, but considering how important start and stop are to an instance (for example), they're pretty buried in the current design.
Here's one idea (adding text to the button instead of a simple hamburger [kebab]), but really there's a whole range of possible solutions, for example pulling out dedicated start and stop buttons at top level. A hamburger is more legible as a ...rest kind of thing than as the place where these actions live.
