Abstract
In some embodiments, the invention involves saving limited context information when transitioning between virtual machines. A predetermined set of instructions and events cause a trap. A bit or flag is set to indicate that the event has occurred within a virtual machine. The virtual machine monitor determines whether specific register sets must be saved or restored upon a context switch, based on whether the flag has been set. Other embodiments are described and claimed.
