Virtualization event processing in a layered virtualization architecture |
| 摘要 |
Embodiments of apparatuses and methods for processing virtualization events in a layered virtualization architecture are disclosed. In one embodiment, an apparatus includes a event logic and evaluation logic. The event logic is to recognize a virtualization event. The evaluation logic is to determine whether to transfer control from a child guest to a parent guest in response to the virtualization event. |

1. An apparatus comprising:
a hardware processor including:
event logic to recognize a virtualization event; andevaluation logic to determine whether to transfer control of the apparatus from a child guest to a parent guest in response to the virtualization event by at least checking an event bit of a virtual machine control structure stored in memory corresponding to the virtualization event, wherein an event bit indicates whether the parent guest of the child guest wants control if a particular virtualization event occurs. |
