Abstract: Embodiments of apparatuses, methods, and systems for injecting virtualization events in a layered virtualization architecture are disclosed. In one embodiment, an apparatus includes virtual machine entry logic, recognition logic, and evaluation logic. The virtual machine entry logic is to initiate a transfer of control of the apparatus from a host to a guest running on a virtual machine. The recognition logic is to recognize a request from the host to inject a virtualization event into the virtual machine. The evaluation logic is to identify an intervening monitor to handle the virtualization event.

Abstract: In one embodiment, a processor mode is provided for guest software. The processor mode enables the guest software to operate at a privilege level intended by the guest software. When the guest software attempts to perform an operation restricted by the processor mode, the processor mode is exited to transfer control over the operation to a virtual-machine monitor, which runs outside this processor mode.

Abstract: Embodiments of apparatuses, methods, and systems for guests to access memory mapped devices are disclosed. In one embodiment, an apparatus includes evaluation logic and exit logic. The evaluation logic is to determine, in response to an attempt of a guest to access a device using a memory address mapped to the device and based on an access type, whether the access is allowed. The exit logic is to transfer control to a host if the evaluation logic determines that the access is not allowed.

Abstract: An embodiment of the present invention is a technique to perform address translation. A table structure is indexed by a source identifier of an input/output (I/O) transaction specifying a guest physical address and requested by an I/O device to map the I/O device to a domain assigned to the I/O device. An address translation structure translates the guest physical address to a host physical address corresponding to the I/O transaction.

Abstract: Methods and systems to provide support for single stepping a virtual machine in a virtual machine environment are disclosed. An exemplary method may include receiving a request to transition control to a virtual machine (VM) from a virtual machine monitor (VMM), determining that a single-stepping indicator is set to a single stepping value, and transitioning control to the VM. Further, if an execution of a first instruction in the VM completes successfully, control is transitioned to the VMM following the successful completion of the execution of the first instruction.
