Abstract: Techniques for dynamic management of virtual machine environments are disclosed. For example, a technique for automatically managing a first set of virtual machines being hosted by a second set of physical machines comprises the following steps/operations. An alert is obtained that a service level agreement (SLA) pertaining to at least one application being hosted by at least one of the virtual machines in the first set of virtual machines is being violated. Upon obtaining the SLA violation alert, the technique obtains at least one performance measurement for at least a portion of the machines in at least one of the first set of virtual machines and the second set of physical machines, and a cost of migration for at least a portion of the virtual machines in the first set of virtual machines. Based on the obtained performance measurements and the obtained migration costs, an optimal migration policy is determined for moving the virtual machine hosting the at least one application to another physical machine.

Abstract: A system and method for transforming a legacy device into a virtualized environment, comprising includes analyzing the profiling data for at least one application to determine usage frequency and resource requirements of the at least one application. Captured user events are benchmarked to simulate a user workload for the at least one application to determine how resource utilization and execution times scale from a legacy environment to a virtualized environment. The legacy device is transformed into the virtualized environment in accordance with a provisioning plan.

Abstract: A plurality of user interactions in a baseline computing system are intercepted and recorded, in an artifact file, with a benchmarking tool. The recorded user interactions from the artifact file are replayed and injected to a software stack of a system under test (whose performance is to be compared to the baseline system), using the benchmarking tool. During the replay, screen updates in the system under test are sequentially compared with expected screen images from the artifact file, until a match is observed in a given case. A response time associated with each of the matches is recorded.

Abstract: An embodiment is directed to a hybrid cloud environment wherein a user of cloud computing services is disposed to consume cloud provided services delivered by each of a plurality of cloud computing service providers. Specified event data is received at an MCS component, wherein the event data pertains to metering events related to consumed services delivered by one or more cloud service providers. Event data includes event data furnished by one or more entities that actively monitor metering events at one or more local or remote cloud service provider locations. Event data is sent from the MCS component to a metering system, and the metering system generates reports from the event data that contains usage information on services provided by one or more cloud service providers, wherein information for a provider specifies amounts and quality of each type of service delivered to users by the provider.

Abstract: A system and method for transforming a legacy device into a virtualized environment includes gathering profiling data over time to represent legacy device activities and analyzing the profiling data for system applications and user applications using a processor to determine usage frequency and resource requirements of at least one application. Captured user action events are benchmarked to simulate a user workload for the at least one application to determine how resource utilization and execution times scale from a legacy environment to a virtualized environment. One or more scaling factors are determined to produce a plan to provision for legacy services in the virtualized environment. The legacy system is transformed into the virtualized environment in accordance with the plan.

Abstract: A computer implemented method, a computer program product, and data processing system clone virtual machines in a virtual desktop environment. A request to clone a new virtual machine is intercepted, wherein the request was initially sent to a virtual management server. Responsive to intercepting the request, the new virtual machine is cloned from a snapshot of a master virtual machine. A delta file is created for the new virtual machine, wherein the delta file includes a base disk reference and a copied delta file. The new virtual machine is configured to read a base disk image from a snapshot of the master virtual machine. The new virtual machine is configured to write data to the copied delta file in the delta file.

Abstract: A system and method for correlating events in data processing resources processing a workload. An event correlation service comprising an event correlation service software framework is provided on a processor unit. The event correlation service is configured, using the event correlation service software framework, for correlating the events from monitored data for the workload, wherein the workload is processed using the data processing resources provided by a provider of the data processing resources. The event correlation service receives monitored data for the workload as the workload is being processed. The monitored data is processed by the event correlation service to identify an occurrence of an event of interest for the workload as the workload is being processed. An output is provided in response to identifying the occurrence of the event of interest.

Abstract: Historical data is measured for a computer server system. Future demand for service in the computer server system is forecast based on the historical data, and the mapping of virtual machines to physical machines is updated based on the forecast of the future demand. Measurement, forecasting, and placement modules can be employed.

Abstract: Integrating data processing resources across a hybrid cloud includes providing a plug-in software component configured to be installed in a software framework. When the plug-in software component is activated, it may generate an interface for a consumer of data processing resources. Using this interface, the consumer of data processing resources may request the use of data processing resources provided as a service on the hybrid cloud. In response, the plug-in software component may acquire the requested data processing resources via interfaces provided by the various data processing resources. A number of different data processing resources may have different interface requirements. However, the first interface generated by the plug-in software component may provide a single vendor neutral interface for accessing data processing resources on the hybrid cloud by the consumer of data processing resources.

Abstract: Installation files are annotated, which annotations may trigger system snapshots to be taken at a plurality of points during the execution of the installation files and/or collected. During a test run, the generated snapshots are examined incrementally to determine whether the installation is success or failure at that point. Checkpoint snapshots are stored, and those indicating failure are recorded with description of the error and/or remediation that suggest how the errors may be resolved or fixed. During a production run, the annotated installation files may be executed and the checkpoint snapshots generated during the production run may be compared with those stored of the test run to incrementally identify and resolve potential problems in the production run.

The first level file system signature may be compared with a first level file system signature pattern associated with one or more previous deployment of the same software and related to the same point in time. Optionally, the second level file system signature may be compared with a second level file system signature pattern.
