Abstract

A custom interrupt service routine may be developed to handle interrupt requests that would not be appropriately handled by either of two operating system guests in a virtualization technology (VT) environment. In some embodiments, the custom interrupt service routine does not in any way interfere with the operation of the interrupt handling in a non-VT environment.
