I can't live migrate the vm's in my cluster:

There is no problem regarding storage or anything like that. If I shut down
the vm I can start it on the other host without any problems whatsoever.
Do I need to do something to make live migration work? Trying to dig in the
logs on the hypervisors, but there's so much stuff being logged there...
