Abstract: A method for migrating virtual machines between hypervisors is disclosed. Initially, metadata describing a virtual machine are automatically scanned and parsed. The structure of the metadata of a source virtual machine are automatically analyzed. Elements of this structure are mapped to corresponding entries of a target virtual machine. A target metadata descriptor to be used as part of the target virtual machine is generated. A predefined layout description of the data stored in a file system image of the source virtual machine read. A predefined layout description of the data to be stored in a file system image to be used at the target virtual machine is also read. The data are extracted from the source virtual machine. A template of a file system image for the target virtual system is generated. Storage space corresponding to the target virtual machine is allocated, and the extracted data are inserted into the allocated storage space.

Abstract: Orders are processed within an Order Processing Environment which includes an Order Processing Container, Relationship Registry, and Factory Registry. The Order Processing Environment is extended by a Reference Resolvement Function Component. The RRFC provides the basic functionality for resolving References defined in the Order Document at runtime and make the referenced data available as a usual input parameter for the resources involved in the Order Processing. Each Task in the Order may contain Resource Property References and Resource Property Relationship References which are pointers to properties of resources. These references are resolved by the RRFC during the Order Processing before the Order Document is delegated from one resource to the next. When resolving a Reference, the value of the referenced Resource Property is determined and the Reference is replaced by this value so that it can be used by the resource having it defined in its Task section as a usual input parameter.

Abstract: The present invention relates to managing the administration of electronic resources accessible in an electronic network. Grid resources or services are enhanced with a presentation interface that provides an administration user-interface for configuring them. Resource-located logic configures the resource according to user inputs and actions imparted on user controls, which are sent from a respective resource to a portal server. On the portal server, a second user-interface software is implemented, able to aggregate the fragments or controls of different resources, to display such multiple controls to a user, to process user inputs imparted on those controls, and to send user control data entered via the user-interface fragments to a resource configuration interface of a respective one of the resources to perform the configuration of a respective resource via the respective resource configuration-interface.

Abstract: A method and system for automated error handling in system management flows by enhancing workflow engines by an error handling component and by adding a supportive error handling layer to invoked system management tasks which serves as the counterpart to the workflow engine's error handling component.

Abstract: A method and system for automatically cloning IT resource structure in stateful web services environments by employing a new approach for configuration management. The present new approach models the configurational state of each resource as a stateful web service. Configuration data are provided by this service's resource properties. Relationships between configurations of different resources are modeled as “stateful web services relationships” between web service instances. These relationships can be navigated, which allows exploring the configuration of a whole system in a standards-based way. Additionally a new web service interface is provided by the stateful web service encapsulating the resource. This interface provides two new operations: “getConfiguration” allows an exploiter to take a snapshot of a resource's and related resources' configurational state and “setConfiguration” allows for setting the configurational state of a resource to a previously saved state.
