Claim Text:
1. A computer program product comprising a non-transitory computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to: create a blocked domain around an entitled virtual machine (VM) and one or more processors allocated to the entitled VM; implement a first dispatching algorithm that prevents the dispatching of processes from other operating systems within other VMs to the one or more processors allocated to the entitled VM; responsive to utilization of the one or more processors allocated to the entitled VM falling below a predetermined threshold, implement a second dispatching algorithm that allows dispatching of processes from the other operating systems within the other VMs to the one or more processors allocated to the entitled VM so that the processes from the other operating systems within the other VMs execute concurrently with processes from an operating system within the entitled VM on the one or more processors allocated to the entitled VM; after implementing the second dispatching algorithm, responsive to utilization of the one or more processors allocated to the entitled VM rising above the predetermined threshold, determine a rate of utilization increase of the one or more processors allocated to the entitled VM; and responsive to the rate of utilization of the one or more processors allocated to the entitled virtual machine failing to increase above a predetermined increase rate, implement a third dispatching algorithm that blocks dispatch of any additional processes from the other operating systems of the other VMs to the one or more processors allocated to the entitled VM and allows executing processes from the other operating systems of the other VMs to finish execution normally.
