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.

摘要： Approaches for synchronizing cookie data across a virtualized web browser. When a user instructs a virtualized web browser, executing on a host operating system, to display a web page, a host module executing on the host operating system instructs a particular virtual machine to retrieve the web page within the particular virtual machine. The host module provides cookie data for the user to the guest module. The cookie data identifies one or more cookies deemed to be pertinent to the retrieval of the web page. The guest module provides, to the host module, screen data content for use in displaying the web page.

摘要： Managing the guest operating system's eviction of memory pages from a virtual machine. A guest operating system or a hypervisor may cause one or more memory pages within a guest physical frame to become unlikely or ineligible for selection as a candidate for eviction by the guest operating system. Each of the one or more memory pages may also reside, or be intended to reside, in the memory of one or more other virtual machines. In this way, memory pages that are shared across multiple virtual machines may become less likely to be evicted, thereby using memory more efficiently.

摘要： Reducing an amount of memory used by a virtual machine. A system includes multiple virtual machines that share common pages of memory. The number of private pages associated with each virtual machine is minimized by ensuring that pages that a guest operating system regards as now free or zeroed are efficiently mapped by the hypervisor to a shared zero page. Upon a hypervisor determining that one or more guest physical frame numbers are assigned to free memory pages, the hypervisor updates mapping data to map the one or more guest physical frame numbers to a shared zero page within the machine frame.

摘要： Approaches for synchronizing history data across a virtualized web browser. When a user instructs a virtualized web browser, executing on a host operating system, to display a web page, a host module executing on the host operating system may instruct a guest module executing within a particular virtual machine to retrieve the web page. The host module may provide to the guest module history data for the virtualized web browser. History data describes browsing history for the virtualized web browser, either in the current instance or for previous instances. The guest module performs operations in accordance with the history data. When the host module receives the screen data content from the guest module, the host module instructs the virtualized web browser to display the web page using the screen data content.

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 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： Mitigating eviction of the memory pages of virtualized machines. Upon detecting that a request to perform an I/O operation has been issued against a block stored a disk, a determination is made as to whether a pristine copy of the contents of the block is stored in memory. If a pristine copy of the contents of the block is stored in memory, then the request may be performed by updating mapping data that maps a page of memory to a location in memory at which the pristine copy is stored. In this way, the request is performed without performing the I/O operation against the block stored on disk. Various approaches for resharing memory, including memory of a template virtual machine, are discussed.

摘要： Approaches for transferring data to a client by safely receiving the data in or more virtual machines. In response to the client determining that digital content, originating from an external source, is to be received or processed by the client, the client identifies, without human intervention, one or more virtual machines, executing or to be executed on the client, into which the digital content is to be stored. In doing so, the client may consult policy data to determine a placement policy, a containment policy, and a persistence policy for any virtual machine to receive the digital content. In this way, digital content, such as executable code or interpreted data, of unknown trustworthiness may be safely received by the client without the possibility of any malicious code therein from affecting any undesirable consequence upon the client.
