Abstract
Methods, systems, and computer program products for using a stored interrupt location to provide fast interrupt register access in hypervisors are presented. A computer-implemented method may include maintaining an area of memory in a hypervisor to track a location of an interrupt vector corresponding to an asserted interrupt in a virtual machine, storing the location of the interrupt vector in the area of memory when responding to the asserted interrupt, and examining the area of memory to determine when an interrupt is present in the virtual machine.
