Pro 484 points 13 March 2012 10:39 AM Jose Antonio Vico Palomino There is no way to do it, like Xen, without stopping the machines? It's like going back to the stone age. :-( Thanks.

Hot adding memory and cpu has high priority in the list of future features and is already in the roadmap for a future version.
