virtinfo - virtual environment information
virtinfo [-acdptsu] virtinfo [-c {<class>[,...] | all}] [<subcommand>] list [[-H] -o <field>[,...]] [<environment>] ... get [[-H] -o <field>[,...]] {all | <property>[,...]} [<environment>] ...
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.
The virtinfo command supports the following option:
SPARC only: Execute with all flags.
SPARC only: Report if a control domain.
SPARC only: Report domain name.
SPARC only: Parsable format.
SPARC only: Report domain role.
SPARC only: Report chassis serial number.
SPARC only: Report UUID.
Choose from available virtual environment classes: current, parent, supported, or unsupported.
Without the –c option, all classes are assumed.
The virtinfo command supports the following subcommands:
Lists all virtual environments from chosen environment classes. The list can be limited by listing environments of interest. For each environment the following fields are displayed:
Environment name
Environment class. It can be current, parent, supported, or unsupported.
Used for scripting mode. This option does not print headers and separates fields by a single tab instead of arbitrary white space.
Displays a comma-separated list of fields.
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:
Environment name
Environment class
Property name
Property value
Used for scripting mode. This option does not print headers and separates fields by a single tab instead of arbitrary white space.
Displays a comma-separated list of fields.
If the subcommand is used to print selected properties (i.e. all is not used), all possible combinations of chosen classes and virtual environments, and selected properties are assumed and virtinfo errors out on the first invalid combination it iterates through. No partial output consisting of remaining valid combinations of a class, virtual environment, and property is printed in such a situation.
The following exit values are returned:
Successful completion.
An error occurred.
The following example shows the default output:
$ virtinfo NAME CLASS logical-domain current logical-domain parent non-global-zone supported kernel-zone supported logical-domain unsupported
The current domain is an LDoms guest domain. Both non-global zones and kernel-zones are supported as guests. Non-control logical domains always show logical-domain as the parent. LDoms guests cannot be created as guests.
Example 2 Getting All Properties for all Classes and Virtual Environments from within a Kernel Zone Virtual EnvironmentBy providing all properties, the following example shows that the kernel-zone virtual environment is not supported from within Kernel Zones, and its status property provides the reason why not. It also shows that the solaris branded Zones are supported. As this example is run on bare metal x86 architecture, there is no parent class virtual environment.
$ virtinfo get all NAME CLASS PROPERTY VALUE kernel-zone current zonename bumblebee non-global-zone supported - - kernel-zone unsupported status not supported in kernel-zoneExample 3 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 supportedExample 4 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 1228BDY5D4Example 5 Selecting a Property not Supported in Every Combination of a Class and Virtual Environment
The following example fails because the non-global-zone virtual environment in the supported class has no zonename property. As explained in the get subcommand section, if specific properties are queried, virtinfo errors out on the first invalid combination of a class, environment, and property.
$ virtinfo get zonename virtual environment 'non-global-zone' in class 'supported' does not support property: zonename
However, because the zonename property is supported for the kernel-zone environment in the current class if queried from within a Kernel Zone, we can narrow down the query. Note that you can always use get all to print only valid combinations of chosen classes and virtual environments with all available properties.
$ virtinfo -c current get zonename kernel-zone NAME CLASS PROPERTY VALUE kernel-zone current zonename kz1Example 6 From Within a Kernel Zone, Only Print the Current Virtual Environment zonename Property Value
This command prints the Kernel Zone name as used in the host.
$ virtinfo -c current get -H -o value zonename kernel-zone kz1
