System Administration Commands virtinfo(1M) NAME virtinfo - Virtual environment information SYNOPSIS virtinfo [[-c <class>[,...] | all] <subcommand>] list [[-H] -o <field>[,...]] [<environment>] ... get [[-H] -o <field>[,...]] all | <property>[,...] [<environment>] ... help property | environment DESCRIPTION The virtinfo utility provides virtualization information returned by libv12n(3LIB) about the current environment, parent environment and a list of supported environments. If no options are specified, virtinfo performs the equivalent of "virtinfo list". OPTIONS The virtinfo command supports the following options: -a Shows all information that is currently available from the sys- tem. -c The class of virtual environment: current, parent, or supported. SUB-COMMANDS The virtinfo command supports the following subcommands: list [[--H] -o <field>[,...]] [<environment>] ... Lists the current, parent, and supported environments. The list can be limited by listing environments of interest. For each environ- ment the following fields are displayed: name Environment name class Environment class. It can be current, parent, or sup- ported. -H Used for scripting mode. This option does not print headers and separates fields by a single tab instead of arbitrary white space. -o field Displays a comma-separated list of fields. get [[-H] -o <field>[,...]] all | <property>[,...] [<environment>] ... Retrieve a property of an environment. Properties are environment and class specific. For example an LDoms supported environment may support different properties to an LDoms current environment. The environment list to query can be limited by listing environments of interest. For each property the following fields are displayed: name Environment name class Environment class property Property name value Property value -H Used for scripting mode. This option does not print headers and separates fields by a single tab instead of arbitrary white space. -o field Displays a comma-separated list of fields. help property | environment List all the property or environment names. The list of avail- able properties and environments may vary with machine archi- tecture. If a property value is not available, due to lack of sufficient privileges, "-" is displayed in its place. EXIT STATUS The following exit values are returned: 0 Successful completion. >0 An error occurred. EXAMPLES Example 1 Viewing Default Information The following example shows the default output: $ virtinfo NAME CLASS logical-domain current non-global-zone supported kernel-zone supported The current domain is an LDoms guest domain. Both non-global zones and kernel-zone are supported as guests. The parent virtual environment class could not be determined. Example 2 Check to see if Kernel Zones are Supported The following example shows how to check if the current environment is capable of supporting a Kernel Zone: $ virtinfo -c supported list kernel-zone NAME CLASS kernel-zone supported Example 3 Viewing All LDoms Properties in a Parsable Format The following example shows all available information about an LDoms environment in a parsable format: $ virtinfo -c current get -H -o property,value all logical-domain control-role true io-role true root-role true service-role true domain-name primary uuid da64f9b8-3e37-688e-cc3f-e90a59db1ad control-name leftarrow chassis-serial-number 1228BDY5D4 ATTRIBUTES See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |system/library/libv12n | +-----------------------------+-----------------------------+ |Interface Stability |Uncommitted | +-----------------------------+-----------------------------+ SEE ALSO libuuid(3LIB), libv12n(3LIB) SunOS 5.11 18 Nov 2013 virtinfo(1M)
