摘要： The techniques disclosed herein synchronize focus between two operating systems that run concurrently. A proxy application running on a primary operating system (OS) presents a guest application running in a secondary OS as if it was native to the primary OS. User interface events received by the proxy application are forwarded to the corresponding guest application. Each OS independently identifies which application currently has focus. When the primary OS is focused on a proxy application, focus is synchronized by setting and maintaining the focus of the secondary OS to the corresponding guest application. When the primary OS is not focused on a proxy application, the focus of the secondary OS is set to a stub placeholder application. Keeping focus synchronized prevents user interface events received by the proxy application from being forwarded to the wrong application on the secondary OS.

摘要： A container image is received at a host device. The container image includes a container application compatible with a first operating system, and the host device includes a second operating system, different from the first operating system. A container engine on a processing device executes a container corresponding to the container image. The container engine includes an emulator configured to translate a request from the container application that is directed to the first operating system into a request to the second operating system.

摘要： Aspects of the present disclosure relate to flexible and automatic provisioning of virtual instances in a virtual network using single-root input/output virtualization. A device pool is defined that is associated with a virtual entity, such as a virtual switch, in a data center. The device pool identifies available physical hardware devices of one or more host machines, such physical network interfaces connected to the virtual switch, and the device pool is associated with the virtual entity. When a virtual computing instance is connected to the virtual entity, such as when initialized or after migrating between hosts, one or more physical hardware devices are automatically assigned from the device pool to the virtual computing instance based on the association of the device pool to the connected virtual entity. Thus, VMs can be flexibly and automatically provisioned with SR-IOV physical hardware when migrating between hosts using SR-IOV.

摘要： Described herein are methods, device, and systems that provide security to various computing systems, such as, smartphones, tablets, personal computers, computing servers, or the like. Security is provided to computing systems at various stages of their operational cycles. For example, a secure boot of a base computing platform (BCP) may be performed, and security processor (SecP) may be instantiated on the BCP. Using the SecP, an integrity of the OS of the BCP may be verified, and an integrity of a hypervisor may be verified. A virtual machine (VM) may be created on the BCP. The VM is provided with virtual access to the SecP on the BCP. Using the virtual access to the TAM, an integrity of the guest OS of the VM is verified and an integrity of applications running on the guest OS are verified.

摘要： Embodiments of techniques and systems for execution of code with multiple page tables are described. In embodiments, a heterogenous system utilizing multiple processors may use multiple page tables to selectively execute appropriate ones of different versions of executable code. The system may be configured to support use of function pointers to virtual memory addresses. In embodiments, a virtual memory address may be mapped, such as during a code fetch. In embodiments, when a processor seeks to perform a code fetch using the function pointer, a page table associated with the processor may be used to translate the virtual memory address to a physical memory address where code executable by the processor may be found. Usage of multiple page tables may allow the system to support function pointers while utilizing only one virtual memory address for each function that is pointed to. Other embodiments may be described and claimed.

摘要： A system for an agnostic runtime architecture is disclosed. The system includes a system emulation/virtualization converter, an application code converter, and a system converter wherein the system emulation/virtualization converter and the application code converter implement a system emulation process, and wherein the system converter implements a system conversion process for executing code from a guest image. The system converter further comprises a guest fetch logic component for accessing a plurality of guest instructions, a guest fetch buffer coupled to the guest fetch logic component and a branch prediction component for assembling the plurality of guest instructions into a guest instruction block, and a plurality of conversion tables including a first level conversion table and a second level conversion table coupled to the guest fetch buffer for translating the guest instruction block into a corresponding native conversion block. The system further includes a native cache coupled to the conversion tables for storing the corresponding native conversion block, a conversion look aside buffer coupled to the native cache for storing a mapping of the guest instruction block to corresponding native conversion block. Upon a subsequent request for a guest instruction, the conversion look aside buffer is indexed to determine whether a hit occurred, wherein the mapping indicates the guest instruction has a corresponding converted native instruction in the native cache, and in response to the hit the conversion look aside buffer forwards the translated native instruction for execution.

摘要： According to a system and method, for composing a virtual disk for a virtual desktop, the virtual desktop is booted from a virtual disk comprised of a base disk image and a user delta disk image that receives all disk writes to the virtual disk. Disk space is allocated on the virtual disk for a file associated with a selected application to be provided to a user of the virtual desktop. Then the virtual desktop is recomposed offline by linking the bass disk image, an application delta disk image including the file associated with the selected application, and the user delta disk image. The recomposing includes modifying meta data of the application delta disk and the user delta disk so that the file associated with the selected application is mapped to the disk space previously allocated.

摘要： Methods for supporting wide and efficient front-end operation with guest architecture emulation are disclosed. As a part of a method for supporting wide and efficient front-end operation, upon receiving a request to fetch a first far taken branch instruction, a cache line that includes the first far taken branch instruction, a next cache line and a cache line located at the target of the first far taken branch instruction is read. Based on information that is accessed from a data table, the cache line and either the next cache line or the cache line located at the target is fetched in a single cycle.
