It should be possible to hot-add and hot-remove CPU cores from a virtuel server based on server load rules configured on the control panel. It is not enough to be able to modify CPU priority. The possibility to automatically add or remove CPU cores from a virtual server using auto-scale will provide the needed flexibility and scalability.
While I am aware that it's possible to duplicate a virtual server with the load balancer appliance, often this won't work as the virtual server that needs more CPU-resources is also hosting a database.
