Abstract
In one embodiment, in accordance with the present invention, a method, computer program product, and system for accessing non-functional host capabilities and services of a host operating system, by a guest operating system, are provided. The method includes a hypervisor, of a host OS, intercepting a hardware instruction from a guest operating system, wherein the hardware instruction is associated with data located in a register and in memory that is accessible by the hypervisor. The method further includes analyzing the hardware instruction and data to determine if the hardware instruction is a non-functional service request. The method further includes, upon determining that the hardware instruction is a non-functional service request, executing the related non-functional service request and writing a response to the associated memory. The method further includes notifying the guest operating system that the execution of the non-functional service request is complete and the response is available.
