Methods, systems and computer program products for fast interrupt register access in hypervisors are provided. A computer-implemented method may include maintaining a counter associated with a register to track set interrupt vectors in a virtual machine, updating the counter in response to an interrupt event in the virtual machine, and examining the counter to determine when an interrupt vector is set.
