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 providing a guest operating system to a virtual machine. A read-only copy of one or more disk volumes, including a boot volume, is created. A copy of a master boot record (MBR) for the one or more disk volumes is also stored. The read-only copy may be, but need not be, made using a Volume Shadow Copy Service (VSS). A virtual disk, for use by the virtual machine, is created based on the read-only copy of the one or more disk volumes and the copy of the master boot record (MBR), wherein the virtual disk comprises the guest operating system used by the virtual machine. In this way, a single installed operating system may provide both the host operating system and the guest operating system.

摘要： Representing a non-executing virtual machine with a graphical representation. 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 to a non-executing state. An image that represents the virtual machine is displayed. The image is based upon the state of the virtual machine immediately prior to the virtual machine entering the non-executing state.

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 ensuring a document does not inadvertently link or contain to any malicious content. A request from a document embedded within a parent web page itself, or comprised within a window launched by the parent web page, is received. The request is executed in a memory address space separate from a memory address space in which the parent web page resides. The execution of the request is performed using a parent proxy that represents the parent web page. Any malicious actions resulting from the performance of the request affect the parent proxy rather than the parent web page. The parent proxy provides at least a portion of the results of executing the request to a child proxy, which in turn determines what, if any, content within the results should be sent to the web browser rendering the parent web page.
