Embodiments of apparatuses and methods for improving performance in a virtualization architecture are disclosed. In one embodiment, an apparatus includes a processor and a processor abstraction layer. The processor abstraction layer includes instructions that, when executed by the processor, support techniques to improve the performance of the apparatus in a virtualization architecture.

Performance in a virtualization architecture with a processor abstraction layer

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.
