Embodiment Construction

[0032] An embodiment can be used with templates of any size without limitation. Currently, typical templates are on the order of gigabits (GB) in size. A typical virtualized data processing environment may employ hundreds or even thousands of different VM configurations. Thus, such an environment may store hundreds or thousands of templates corresponding to those VM configurations.

[0033] Generally, when a compute node has to install a VM with a specific configuration, the compute node transmits the corresponding template from the template repository over the data network. In some virtualized data processing environments, copies of certain templates are stored or pre-provisioned on certain computing nodes so that when a corresponding VM is needed, the VM can be quickly created without transferring the template over a data network.

[0034] The exemplary embodiments recognize that actual compute nodes have limited local or remote storage space in which to store templates. ...

Abstract

Exemplary embodiments include a method, system, and computer program product for creating a virtual machine using a pre-provisioned mutated template. A template to be used to create the virtual machine is identified, the template including data usable to create the virtual machine on the data processing system. Select chunks of data in a mutated template for use in reconstructing a template from a mutated template. The data chunk is included in the mutation template at the location specified in the manifest associated with the mutation template. The data structure of the template is populated with the data block such that the data block occupies a predetermined location in the template, thereby reconstructing the template from the mutated template. Use this template to create a virtual machine on the data processing system.

Description

technical field [0001] The present invention mainly relates to a method, system and computer program product for installing or provisioning a virtual machine. In particular, the present invention relates to a method, system and computer program product for using pre-provisioned mutated templates for installing multiple virtual machine (VM) configurations on computing nodes. Background technique [0002] Certain data processing systems are configured to process several workloads simultaneously. For example, multiple independent virtual data processing systems, such as independent VMs, configured on a single host data processing system, often process independent workloads for different clients or applications. Host data processing systems are also referred to as compute nodes. [0003] In a large-scale data processing environment, such as in a data center, thousands, if not thousands, of VMs may be operating on a host machine at any given time, and hundreds if not thousands ...
