ABSTRACT:
A technique to improve the performance of virtualized input/output (I/O) resources of a microprocessor within a virtual machine environment. More specifically, embodiments of the invention enable accesses of virtualized I/O resources to be made by guest software without necessarily invoking host software. Furthermore, embodiments of the invention enable more efficient delivery of interrupts to guest software by alleviating the need for host software to be invoked in the delivery process.
