Systems, methods and computer-readable storage media are disclosed for providing a virtual single-user session to a client in a terminal server session. In an embodiment, requests to a resource in the system-space of a system made by an application are intercepted. A determination is made as to whether to virtualize the resource for the application. Where the resource is to be virtualized, a user-specific virtualized resource is created or maintained in user-space and provided to the application.

A system creates a storage area network (SAN) centric storage virtualization layer in front of storage devices. The system allows data mobility and migration without disruption to the one or more host servers attached to the SAN. Specifically, the host servers are not disrupted when switching I/Os between physical and virtual storage, for example, by taking advantage of WWPN spoofing and Fibre Channel VSAN technology. The use of VSANs effectively allow multiple virtual directors and/or switches to be created within a physical director and/or switches, each with their own separate name server, thereby providing complete isolation from one another. The host-storage pathing information is unchanged as the original physical storage port's WWPNs are spoofed by the virtual storage port. The result is two identical WWPNs within the SAN which is normally disallowed; however, by separating the physical port WWPN into one VSAN and the virtual port WWPN into another, the restriction may be circumvented.

The present invention provides an application virtualization framework that allows dynamic allocation and de-allocation of compute resources, such as memory. Runtime applications are pooled across multiple application servers and compute resources are allocated and de-allocated in such a way that resource utilization is optimized. In addition, objects are either stored in local memory or in a non-local memory pool depending on certain criteria observed at runtime. Decision logic uses decision rules to determine whether an object is to be stored locally or in a memory pool. Resource management logic monitors the memory pool to determine which locations are available for storing objects and how much memory is available overall in the memory pool for storing objects.

An extension point virtualization system uses operating system-provided reparse points to provide minimal extension point registration. Reparse points preserve application isolation while removing the scale problem of writing custom extension point proxies for each extension point. Instead, the system can use a single file system filter that generically handles application virtualization reparse points, and store reparse point data for extension points that need redirection. Many extension points can be handled by redirecting the operating system from a typical location for an application resource to a virtualized safe location for the application resource. Thus, the system simplifies the process of handling new extension points by allowing an application virtualization system to simply register new locations that should be handled with reparse points and to then handle registered locations generically.

A method and system for providing a virtual clock on a computer by multiplying the number of instructions executed by the average instruction execution time. It is however not reliable to use this generic computation for virtualization of application in a fault tolerant system because the virtual clock computed like this quickly deviates from the system clock. A virtual clock computation is provided which includes periodic readjustment of the virtual to the system clock. Also, the errors coming from rounding of the number of executing instruction are suppressed.

Taking the assumption that the user instruction counters are maintained synchronized in the operational and the replication computers, replacing the system clock access by a virtual clock when virtualizing applications thus turning the system clock acquisition into a deterministic event. Replicating the system clock access can be thus done by reexecuting the application code in the replication machine avoiding transfer of information at each system clock access of the virtualized application programs.
