摘要：
A mechanism is provided for temporarily allocating dedicated processors to a shared processor pool. A virtual machine monitor determines whether a temporary allocation associated with an identified dedicated processor is long-term or short-term. Responsive to the temporary allocation being long-term, the virtual machine monitor determines whether an operating frequency of the identified dedicated processor is within a predetermined threshold of an operating frequency of one or more operating systems utilizing the shared processor pool. Responsive to the operating frequency of the identified dedicated processor failing to be within the predetermined threshold, the virtual machine monitor either increases or decreases the frequency of the identified dedicated processor to be within the predetermined threshold of the operating frequency of the one or more operating systems utilizing the shared processor pool and temporarily allocates the identified dedicated processor to the shared processor pool.
