One or more concurrency limits may be checked in connection with the performance of a virtual machine management operation such as a virtual machine deploy, resize or migration operation to enable the virtual machine management operation to be scheduled on a host for which no concurrency limits have been met.

Management of a virtual machine in a virtualized computing environment based on a concurrency limit

A method, apparatus, and computer instructions for providing addresses to clients. A request is received from a client for an address. A determination is made as to whether authentication information is present in the request. A verification process is performed using the authentication information if the authentication information is presenting the request. A determination is made as to whether the authentication information is authenticated. A privileged address is provided to the client in response to the authentication information being authenticated.

Method and apparatus for authenticated network address allocation

A system and method are provided to allow a user to update a computer system without having to interact with an initialization, or configurator software utility, or program. More particularly, the present invention allows a system provider, manufacturer, or service provider to create an installation file that, when provided to a user, will configure a system to accommodate newly added/removed hardware automatically. A base model and a new model of the system are maintained. The new model will include one or more different configurations, such as new graphics adapters, communications adapters, I/O controllers, or the like. The provider will have created a recovery/install image to be used with the base model. An operating system including a configurator program will be running on both the base model system and new model system. Software, such as device drivers, to be used with the new model's changed hardware configuration is installed on the new model system and initialized using its configurator program. A file for the new model is created using vital product data for the base model system. This new model configuration file is then installed on the base model machine and its configurator program is run. The configuration information (including the new model configuration data) is then stored as a system image and a script file is added to this system image. This new model image is then made available to end users, by a CD or the like, having a new model system. The script file in the new model image will specify a start priority that will allow it to be called before the configurator program and it will proceed to initialize the system with the appropriate software captured from the system provider's new model machine.

A method, system, and computer program product are disclosed for managing an application's persistent data across multiple different release versions of the application. A format for a memory area is defined wherein the persistent data will be stored according to a first release version of the application. The format is organized to permit the application running at different release versions to access the memory area. The memory area is accessed using the application that is running at a second release version. The memory area is divided into individually accessible sections. The format includes a template file for each section for each release version.

Method, system, and computer program product for managing persistent data across different releases

A method, apparatus, and computer instructions for improving performance and scalability of common information model object (CIMOM) by using a hardware management console (HMC) repository. The HMC repository includes storage of HMC objects, an HMC object model and a common interface (CIM Wrapper) for accessing to HMC objects. The HMC object model allows the user to store and retrieve the CIM objects and their associations efficiently. A CIM provider may access HMC objects through a common interface (CIM Wrapper), so that different repositories are allowed to be used without significant changes to the underlying server code (CIM provider). A CIM provider may also call the HMC repository directly for more efficient operations because the number of times conversions made between the CIM object and the repository object are greatly decreased.

The present invention provides a method, apparatus, and computer instructions for recovering an image of partition configuration information data for a set of partitions having at least one affinity partition in a logical partition data processing system. (Damage to an image of partition configuration data is detected. Current partition data is compared with a backup partition data. A merger of the current partition configuration data is made with the backup logical partition data if a conflict is present between the current partition configuration data and the backup partition data. The merger is performed in a manner avoiding stopping an operation on a running partition in the set of partitions.
