Guest-initiated resource allocation request based on comparison of host hardware information and projected workload requirement

摘要

In general, embodiments of the invention relates to a method for conveying hardware resources from a host (OS) executing on a computer system. The method includes obtaining host hardware information by the host OS, wherein the host hardware information specifies a plurality of physical hardware components of the computer system, sending the host hardware information to a guest OS executing within the host OS, generating, by the guest OS, a resource request using the host hardware information, sending, by the guest OS, the resource request to the host OS, and in response to receiving the resource request, allocating, by the host OS, guest hardware resources, where the guest hardware resources include at least one of the physical hardware components in the resource request.
