Processor that maintains virtual interrupt state and injects virtual interrupts into virtual machine guests
First Claim
1. A processor comprising:
- one or more registers configured to store interrupt state describing a virtual interrupt to be taken by the processor during execution of a guest; and
a control unit coupled to the one or more registers, wherein the control unit is configured to initiate the virtual interrupt responsive to the interrupt state.

Abstract
In one embodiment, a processor comprises one or more registers and a control unit. The registers are configured to store interrupt state describing a virtual interrupt. The control unit is configured to initiate the virtual interrupt responsive to the interrupt state. In another embodiment, a method comprises storing an interrupt state describing a virtual interrupt in a storage area allocated to a guest. A processor initiates the virtual interrupt subsequent to initiating execution of the guest, responsive to the interrupt state. In still another embodiment, a computer accessible medium stores a plurality of instructions comprising instructions which, when executed on a processor in response to a physical interrupt: determine a guest into which a virtual interrupt corresponding to the physical interrupt is to be injected; and store an interrupt state describing the virtual interrupt in a storage area allocated to the guest.
