It would be nicer if we could migrate entire running VM systems from one physical box to another, and not just guest machines from one LPAR to another. Although that would be a nice enhancement as well.
Maybe migrating the entire VM system would be neat, but I don't think it would be my top priority. With current technology (CSE, shared IUCV, shared DASD, etc) you can already build a set of VM systems that look similar enough that you don't care where the virtual machine is running. It would be more flexible if you could move the running virtual machine rather than need a stop / start cycle. I think you would want this most often because you want to do something with VM (e.g. apply CP service), more than doing something to the LPAR or the entire machine. The big challenge would be to have very well defined for which virtual machines it would work. You don't want something like V=R Recovery which worked in theory but requirements were such that it could rarely do so in real life. For Linux virtual machines this looks "doable" (meaning that at SCIDS you can not come up with a real reason why it could not work) even though it will take some tweaking to make it work completely.
