A logical domain is a discrete logical grouping with its own operating systems, resources, and identity within a single computer system. Applications 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 as many as 32 logical domains, depending on the hardware configuration of the server on which the Oracle VM Server for SPARC Manager has been installed. 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, specify a configuration to be used, and list the configurations on the service processor. You can also use the ILOM set /HOST/bootmode config=configfile command to specify an Oracle VM Server boot configuration.
