Abstract
Various technologies and techniques are disclosed that provide fast context switching. One embodiment provides a method for a context switch comprising preloading a host virtual machine context in a first portion of a processor, operating a guest virtual machine in a second portion of the processor, writing parameters of the host virtual machine context to a memory location shared by the host virtual machine and the guest virtual machine, and operating the host virtual machine in the processor. In this manner, a fast context switch may be accomplished by preloading the new context in a virtual processor, thus reducing the delay to switch to the new context.
