Abstract

In an exemplary embodiment of this disclosure, a system may include a first hypervisor, a second hypervisor, and a shared memory set. The first hypervisor and the second hypervisor run over a single logical partition. The shared memory set is accessible by both the first hypervisor and the second hypervisor, and the first hypervisor is configured to communicate with the second hypervisor by writing to the shared memory. The second hypervisor may provide support for hardware that is not supported by the first hypervisor, which hardware may be accessed by the first hypervisor through communications facilitated by use of the shared memory.

First claim

What is claimed is:

1. A computer-implemented method comprising:
running a first operating system over a first hypervisor operating through a first logical partition;
allocating to a second operating system a subset of resources of the first operating system, wherein the first operating system ceases to access the subset of resources directly;
running the second operating system over a second hypervisor operating through the first logical partition, wherein the first hypervi…
