Thanks for the help!

rhevm-3.5.0-0.31.el6ev.noarch?
It sure looks like this bug... But as I said, we are on 3.5.1...

Are you sure that this is indeed a reincarnation of

    Bug 1185818 - [engine-backend] requests don't reach vdsm

? Is vdsm running? Does it show something interesting in its logs?
