摘要:
A virtual environment manager (“VEM”) simplifies the usability of virtual machines and provides users with an enhanced design for creating and/or for managing virtual machines (“VMs”). For example, a user can select description information and management information to be included in descriptors and according to which a VEM will create and manage various VM environments for various host environments. The VEM automatically creates the VM environments and host environments by sending descriptor description information and data files associated with the description information to virtual machine monitors (VMMs), which create the VM environments according to the description information. A VEM at each host may manage VM environments executed by the VMM, according to the descriptor management information. Thus, a set of descriptors to create and manage a set of VMs for a home computer may be easily modified by a user to create and manage a set of VMs for a work or laptop computer.

A method, apparatus and system for improving usability of virtual machines is described. A console module on a VM host may continuously monitor incoming data (e.g., files and/or attachments) and make automatic determinations regarding how and/or whether to intercept, route, redirect and/or deliver the data (e.g., where to store files, when and/or whether to deliver the files, execute the files, etc.). Additionally, in one embodiment, a unification console may be provided to enhance the usability of the VM host. The unification console enables the user to view the VM host via a unified desktop interface while handling the underlying switching and/or interactions between VMs.
摘要:
A method, apparatus and system for transparently unifying virtual machines (“VMs”) is disclosed. An embodiment of the present invention enables a user to interact with various applications on a VM host while unaware of the VM structure on the VM host. The user may be presented with a unified desktop interface representing a composite and/or unified view of the VM host. Via this unified desktop interface, the user may perform all necessary commands and/or receive output. Invisible to the user, the unified desktop interface represents a unification console. The unification console may be an independent component (e.g., an enhanced VM) and/or a subset of a virtual machine manager (“VMM”) component on the VM host. In either situation, the unification console may, alone and/or in conjunction with the VMM, route and/or redirect and/or transform and/or filter the user's commands to the appropriate applications and redirect and/or copy and/or transform and/or filter the output from the applications to be displayed in the unified desktop interface.

Web services, such as UDDI based web services, are intended to operate synchronously, e.g., a client issues a discovery request for availability of a service provider, or the client issues a web service request for service by a discovered service provider, and the client is expected to block/wait until a response is received to the clients request. While this configuration may work effectively when the client has a stable network connection, it is not effective when the client is offline. An environment is disclosed for effectively implementing web services when the client is offline by faking appropriate registry and service provider responses, and then deferring request processing until network connectivity is restored.

A Registry, such as a UDDI registry, dynamically manages (e.g. filters and/or re-orders) answers to service queries by Service Consumers based at least on one or more of the individual states/status of Service Providers, the collective service environment state, and policies employed by the environment. The Registry may be configured to infer operational state/status about a Service Provider, such as impending unavailability due to very low battery reserves, and to remove providers from the registry if determined to be unavailable. The Registry may be configured to associate a shelf-life with a provider registration based on characteristics of the Service Provider, or based on past experience with the Service Provider. Such dynamic management allows the Registry to implement intelligent task distribution and load balancing between Service Providers, and to insulate Service Providers on fragile platforms (e.g. notebooks, handhelds, etc.) that may otherwise be overwhelmed by offering themselves as a traditional provider.

Currently, global registries, such as ones offered by Microsoft Corporation (uddi.microsoft.com) or Hewlett Packard Corporation (uddi.hp.com), are used to register services offered by or desired by networked devices. Unfortunately, these registries are highly centralized and designed to be repositories for long-lived services, and thus are not amenable to operation of mobile devices, such as laptop computers, personal digital assistants, and other devices whose network address may change frequently as they move in and out of various local network environments. Moreover, when such mobile devices form ad hoc networks, access to the centralized repositories may not be available. To address these issues, devices of a local network may be configured to dynamically select a local master, from among devices attached to the local network and based on characteristics of the devices, where the selected device operates a registry for the local network.
摘要:
A traditional registry, such as a global UDDI server, is not designed to accommodate transitory devices, e.g., devices that may frequently attach and detach from a network, often-times without warning, such as virtual machines offering or desiring services that are periodically instantiated and then suspended or destroyed. To accommodate such transitory devices, a dynamic resource/service registry may be implemented that leverages lower-level protocols or state to determine appropriate registry updates to keep the registry state consistent with currently-active virtual machines. For example, a virtual machine monitor (VMM) may track creation and suspension or deletion of a virtual machine (VM), and resources advertised by the VM, where the VMM appropriately adds or removes registry entries for the VM as the state of the VM changes or provides hooks (e.g. notifications) or other instrumentation based on said state or protocols to enable other associated modules or agents (e.g. management modules or the registry) to take appropriate actions.
摘要:
Embodiments of the invention include an access policy enforcement system for a system that provides services to other devices. As a service-providing device changes environments, or mobile states, access to the device's services is automatically and transparently limited or expanded. One aspect of the access policy determines the particular state in which the service-providing device is operating. Another aspect uses the determined state to dictate which services will be available to other devices.
