global maintence mode is already on. hosted-engine --vm-start-paused results in a non-paused VM being started. Of course, this is executed after hosted-engine --vm-poweroff and suitable time left to let things shut down.
I just ran another test, and did in fact see the engine was briefly paused, but then was quickly put in the running state. I don't know by what, though. Global maintence mode is definitely enabled, every run of the hosted-engine command reminds me!
