Abstract
A system and method are disclosed for determining whether to grant requests for additional virtual processors for a virtual machine (referred to as 'processor hotplug requests'). In accordance with one embodiment, a hypervisor receives a request from a guest operating system of a virtual machine, where the request is for an additional virtual processor for the virtual machine. The hypervisor then determines whether or not to grant the request based on a policy.
