Represents the virtualization service present on a single host system. Msvm_VirtualSystemManagementService is used to control the definition, modification, and deletion of virtual machines. It also has methods for performing operations on virtual machines, such as cloning, snapshotting, and the importing or exporting of virtual machines. To retrieve per-virtual machine information, use Msvm_ComputerSystem.
The following syntax is simplified Managed Object Format (MOF) code, and it includes all of the inherited properties.
