When changing the instancetype from cx1.medium->large the maxSockets field is also changed, which in process raise a RestartRequired condition.
This mean that hot-plugging is prevented until restart, but the user does not know or have a general information on any of the processes.
It would be useful to let users know about RestartRequired condition which blocks hot-pluging. This is generic use case and virt should provide with details regarding need for restart.UI can further consume that backend information and populate on UI needs for restart.
