    摘要： Programmatically adjusting the operational state of one or more virtual machines based on policy. Resource consumption on a hardware device is monitored. A policy that considers at least a present level of resource consumption and an amount of available resources of the hardware device is consulted. An operational state of a particular virtual machine that resides on the hardware device is changed. The change in operational state may be performed to optimize performance of a virtual machine with which a user is interacting, to enforce behavior constraints upon the virtual machine, or to adjust its execution in view of the available resources on the device.

    摘要： Approaches for composing the display of a virtualized web browser. A virtualized web browser is instructed to display a web page. The virtualized web browser, in turn, instructs one or more virtual machines to retrieve content for at least a portion of the web page. Each of the one or more virtual machines renders the content retrieved thereby. Upon the virtualized web browser obtaining the rendered screen data content from the one or more virtual machines, the virtualized web browser displays the web page using the rendered content.

    摘要： Approaches for ensuring the privacy of a controller of a device from a host operating system. A host operating system is prevented from inspecting or modifying data received by a controller of a hardware device. Control of the controller is withdrawn from the host operating system and granted to a hypervisor. A replacement controller for the hardware device is provided to the host operating system. Upon the hypervisor receiving data via the controller, the hypervisor forwards the data to a relevant virtual machine responsible for processing the data. Although the host operating system may operate as if it possessed control of the controller of the hardware device, any malicious code inadvertently residing within the host operating system will be unable to inspect or modify any data received by or sent from the actual controller of the hardware device.

    摘要： The present invention is directed towards methods and systems for redirecting an access request to an unsecure virtual machine. A computing device may execute a hypervisor hosting a secure virtual machine and an unsecure virtual machine. A control virtual machine, hosted by a hypervisor executing on the computing device, may intercept a request to access an unsecure resource. The unsecure resource may include one of: a file, an application and an uniform resource locator (URL). The control virtual machine may further determine that the request originates from a secure virtual machine executing on the computing device. The control virtual machine may redirect, responsive to the determination, the request to an unsecure virtual machine executing on the computing device, whereupon the unsecure virtual machine may provide access to the requested unsecure resource.

    摘要： Approaches for transferring a file using a virtualized application. A virtualized application executes within a virtual machine residing on a physical machine. When the virtualized application is instructed to download a file stored external to the physical machine, the virtualized application displays an interface which enables at least a portion of a file system, maintained by a host OS, to be browsed while preventing files stored within the virtual machine to be browsed. Upon the virtualized application receiving input identifying a target location within the file system, the virtualized application stores the file at the target location. The virtualized application may also upload a file stored on the physical machine using an interface which enables at least a portion of a file system of a host OS to be browsed while preventing files in the virtual machine to be browsed.

    摘要： Approaches for processing a digital file in a manner designed to minimize exposure of any malicious code contained therein. A digital file resides with a virtual machine. When the virtual machine receives an instruction to print, fax, or email the digital file, the virtual machine creates, from the digital file existing in an original format, a copy of the digital file in a different format within the virtual machine. The different format preserves a visual presentation of the digital file without supporting metadata or file format data structures of the original format. The virtual machine instructs the host OS to print the copy of the digital file, send a facsimile of the copy of the digital file, or email the copy of the digital file. The host OS may consult policy data in determining how to carry out the request vis-à-vis the digital file.

    摘要： Approaches for synchronizing resources of a virtualized web browser. When a virtualized web browser is instructed to display a web page, a host module executing within a host operating instructs retrieves, from each of one or more virtual machines, contents for a portion of the web page. The virtualized web browser assembles the contents and displays the web page. A web browser executing in the host operating system may, but need not, retrieve any of the content displayed thereby. Instead, the content retrieved by the web browser executing in the host operating system may be retrieved by and rendered within a virtual machine. The behavior of the virtualized web browser may be configured using policy data.
