A logical domain is a discrete logical grouping with its own operating systems, resources, and identity within a single computer system. Application software can run in logical domains. Each logical domain can be created, destroyed, reconfigured, and rebooted independently.
Oracle VM Server for SPARC software enables you to create and manage numerous logical domains on a server, depending on the hardware configuration of the server. You can virtualize resources and define network, storage, and other I/O devices as services that can be shared between domains.
The Oracle VM Server for SPARC configurations are stored on the SP. Using Oracle VM Server for SPARC CLI commands, you can add a configuration, list the configurations on the SP, and specify a configuration to be used. You can also specify an Oracle VM Server boot configuration with an Oracle ILOM command, as explained in Configure the Host Boot Mode (Oracle VM Server for SPARC).
Oracle VM Server for SPARC is included in Oracle Solaris 11.1. If you use Oracle Enterprise Manager Ops Center, you can provision that management environment with a version of Oracle VM Server for SPARC that is compatible with your hardware.
