摘要： Approaches for handling network resources in a virtualized computing environment. A first request for network resources is received from a first virtual machine. Policy data is consulted to determine how to service the first request. The first request is processed by providing the first virtual machine with access to only a first portion of network resources. A second request for network resources is received from a second virtual machine. Policy data is consulted to determine how to service the second request. The second request is processed by providing the second virtual machine with access to only a second portion of network resources that is not coextensive with the first portion. In this way, virtual machines may have access to particular resources and/or specific bounded areas of a network.

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： 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 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： 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.
