Abstract: In a hardware-based virtualization system, a hypervisor switches out of a first function into a second function. The first function is one of a physical function and a virtual function and the second function is one of a physical function and a virtual function. During the switching a malfunction of the first function is detected. The first function is reset without resetting the second function. The switching, detecting, and resetting operations are performed by a hypervisor of the hardware-based virtualization system. Embodiments further include a communication mechanism for the hypervisor to notify a driver of the function that was reset to enable the driver to restore the function without delay.
