A Concept For Controlling Parameters Of A Hypervisor

Abstract: A control apparatus (10), control device, control method and computer program for controlling one or more parameters of a hypervisor (100) and an apparatus, device, method, and computer program for a virtual machine (200). The control apparatus (10) comprises circuitry configured to obtain information on respective performance targets of two or more virtual machines (200) being hosted by the hypervisor (100). The circuitry is configured to set the one or more parameters of the hypervisor (100) to one or more initial values. The circuitry is configured to obtain respective results of a benchmark being run in the two or more virtual machines (200), the results of the benchmark indicating a performance of the respective virtual machines (200) with respect to the respective performance targets, with the results of the benchmark being affected by the one or more parameters. The circuitry is configured to adjust the one or more parameters based on the results of the benchmark and based on the respective performance targets. The circuitry is configured to repeat obtaining the respective results of the benchmark and adjusting the one or more parameters until a termination condition is met.
