摘要： In one embodiment, a method for supporting address translation in a virtual-machine environment includes creating a guest translation data structure to be used by a guest operating system for address translation operations, creating an active translation data structure based on the guest translation data structure, and periodically modifying the content of the active translation data structure to conform to the content of the guest translations data structure. The content of the active translation data structure is used by a processor to cache address translations in a translation-lookaside buffer (TLB).

摘要： 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.

摘要： A system and method for allowing a virtual machine monitor to assume control of a system when the current privilege level of guest software meets a privilege level exiting criteria. The processor detects that the current privilege level meets the criteria and then transfers control from the guest software to the virtual machine monitor. The virtual machine monitor may decline to assume control for certain privilege level changes or values.

摘要： Embodiments of systems, apparatuses, and methods for performing guest logical memory address to host physical memory address translation are described. In some embodiments, a system receives the guest logical memory address and determines an index page reference from the guest logical memory address. The system further retrieves a page index corresponding to the virtual machine. In addition, the system retrieves a first part of the host physical memory address from index page using the page index and a second part of the host physical memory address from the guest logical memory address. The system generates the host physical memory address from the first and second parts of the host physical memory address.

摘要： Methods and systems to implement a physical device to differentiate amongst multiple virtual machines (VM) of a computer system. The device may include a wireless network interface controller. VM differentiation may be performed with respect to configuration controls and/or data traffic. VM differentiation may be performed based on VM-specific identifiers (VM IDs). VM IDs may be identified within host application programming interface (API) headers of incoming configuration controls and data packets, and/or may be looked-up based on VM-specific MAC addresses associated with data packets. VM IDs may be inserted in API headers of outgoing controls and/or data packets to permit a host computer system to forward the controls and/or packets to appropriate VMs. VM IDs may be used look-up VM-specific configuration parameters and connection information to reconfigure the physical device on a per VM basis. VM IDs may be used look-up VM-specific security information with which to process data packets.
