Abstract:
Embodiments of apparatuses, methods, and systems detecting spin loops in a virtual machine environment are disclosed. In one embodiment, an apparatus includes detection logic and virtualization logic. The detection logic is to detect whether a guest is executing a spin loop. The virtualization logic is to transfer control of the apparatus from the guest to a host in response to the detection logic detecting that the guest is executing the spin loop.
