zonecfg help


The zonecfg utility creates and modifies the configuration of a zone. Zone configuration consists of a number of resources and properties.

To simplify the user interface, zonecfg uses the concept of a scope. The default scope is global.

The following synopsis of the zonecfg command is for interactive usage:

zonecfg -z zonename subcommand

Parameters changed through zonecfg do not affect a running zone. The zone must be rebooted for the changes to take effect.

In addition to creating and modifying a zone, the zonecfg utility can also be used to persistently specify the resource management settings for the global zone.

In the following text, “rctl” is used as an abbreviation for “resource control”. See resource_controls(5).

Every zone is configured with an associated brand. The brand determines the user-level environment used within the zone, as well as various behaviors for the zone when it is installed, boots, or is shutdown. Once a zone has been installed the brand cannot be changed. The default brand is determined by the installed distribution in the global zone. Some brands do not support all of the zonecfg properties and resources. See the brand-specific man page for more details on each brand. For an overview of brands, see the brands(5) man page.


The following resource types are supported:


Generic attribute.


Limits for CPU usage.


Limits for physical, swap, and locked memory.


ZFS dataset.


Subset of the system's processors dedicated to this zone while it is running.






Directory inherited from the global zone. Used for sparse root zones (see the discussion of “Sparse and Whole Root Non-Global Zones,” below). Software packages whose contents have been transferred into that directory are inherited in read-only mode by the non-global zone and the non-global zone's packaging database is updated to reflect those packages. Such resources are not modifiable or removable once a zone has been installed with zoneadm.


Network interface.


Resource control.

Sparse and Whole Root Non-Global Zones

In the administration of zones, it is useful to distinguish between the global zone and non-global zones. Within non-global zones, there are two zone root file system models: sparse and whole root. The sparse root zone model optimizes the sharing of objects. The whole root zone model provides the maximum configurability. Note that not all brands support the sparse zone model.

Sparse Root Zones

Non-global zones that have inherit-pkg-dir resources are called sparse root zones.

The sparse root zone model optimizes the sharing of objects in the following ways:

In this model, all packages appear to be installed in the non-global zone. Packages that do not deliver content into read-only loopback mount file systems are fully installed. There is no need to install content delivered into read-only loopback mounted file systems since that content is inherited (and visible) from the global zone.

An additional 40 megabytes of RAM per zone are suggested, but not required on a machine with sufficient swap space.

A sparse zone inherits the following directories:


Although zonecfg allows you to remove one of these as an inherited directory, you should not do so. You should either follow the whole-root model or the sparse model; a subset of the sparse model is not tested and you might encounter unexpected problems.

Adding an additional inherit-pkg-dir directory, such as /opt, to a sparse root zone is acceptable.

Whole Root Zones

The whole root zone model provides the maximum configurability. All of the required and any selected optional Solaris packages are installed into the private file systems of the zone. The advantages of this model include the capability for global administrators to customize their zones file system layout. This would be done, for example, to add arbitrary unbundled or third-party packages.

The disk requirements for this model are determined by the disk space used by the packages currently installed in the global zone.

Note - If you create a sparse root zone that contains the following inherit-pkg-dir directories, you must remove these directories from the non-global zone's configuration before the zone is installed to have a whole root zone:


Each resource type has one or more properties. There are also some global properties, that is, properties of the configuration as a whole, rather than of some particular resource.

The following properties are supported:
































dir, special, raw, type, options




address, physical, defrouter




name, value


name, type, value




ncpus, importance


physical, swap, locked



As for the property values which are paired with these names, they are either simple, complex, or lists. The type allowed is property-specific. Simple values are strings, optionally enclosed within quotation marks. Complex values have the syntax:


where each <value> is simple, and the <name> strings are unique within a given property. Lists have the syntax:


where each <value> is either simple or complex. A list of a single value (either simple or complex) is equivalent to specifying that value without the list syntax. That is, “foo” is equivalent to “[foo]”. A list can be empty (denoted by “[]”).

In interpreting property values, zonecfg accepts regular expressions as specified in fnmatch(5). See EXAMPLES.

The property types are described as follows:

global: zonename

The name of the zone.

global: zonepath

Path to zone's file system.

global: autoboot

Boolean indicating that a zone should be booted automatically at system boot. Note that if the zones service is disabled, the zone will not autoboot, regardless of the setting of this property. You enable the zones service with a svcadm command, such as:

# svcadm enable svc:/system/zones:default

Replace enable with disable to disable the zones service. See svcadm(1M).

global: bootargs

Arguments (options) to be passed to the zone bootup, unless options are supplied to the “zoneadm boot” command, in which case those take precedence. The valid arguments are described in zoneadm(1M).

global: pool

Name of the resource pool that this zone must be bound to when booted. This property is incompatible with the dedicated-cpu resource.

global: limitpriv

The maximum set of privileges any process in this zone can obtain. The property should consist of a comma-separated privilege set specification as described in priv_str_to_set(3C). Privileges can be excluded from the resulting set by preceding their names with a dash (-) or an exclamation point (!). The special privilege string “zone” is not supported in this context. If the special string “default” occurs as the first token in the property, it expands into a safe set of privileges that preserve the resource and security isolation described in zones(5). A missing or empty property is equivalent to this same set of safe privileges.

The system administrator must take extreme care when configuring privileges for a zone. Some privileges cannot be excluded through this mechanism as they are required in order to boot a zone. In addition, there are certain privileges which cannot be given to a zone as doing so would allow processes inside a zone to unduly affect processes in other zones. zoneadm(1M) indicates when an invalid privilege has been added or removed from a zone's privilege set when an attempt is made to either “boot” or “ready” the zone.

See privileges(5) for a description of privileges. The command “ppriv -l” (see ppriv(1)) produces a list of all Solaris privileges. You can specify privileges as they are displayed by ppriv. In privileges(5), privileges are listed in the form PRIV_privilege_name. For example, the privilege sys_time, as you would specify it in this property, is listed in privileges(5) as PRIV_SYS_TIME.

global: brand

The zone's brand type.

global: ip-type

A zone can either share the IP instance with the global zone, which is the default, or have its own exclusive instance of IP.

This property takes the values shared and exclusive.

global: hostid

A zone can emulate a 32-bit host identifier to ease system consolidation. A zone's hostid property is empty by default, meaning that the zone does not emulate a host identifier. Zone host identifiers must be hexadecimal values between 0 and FFFFFFFE. A 0x or 0X prefix is optional. Both uppercase and lowercase hexadecimal digits are acceptable.

fs: dir, special, raw, type, options

Values needed to determine how, where, and so forth to mount file systems. See mount(1M), mount(2), fsck(1M), and vfstab(4).

inherit-pkg-dir: dir

The directory path.

net: address, physical, defrouter

The network address and physical interface name of the network interface. The network address is one of:

  • a valid IPv4 address, optionally followed by “/” and a prefix length;

  • a valid IPv6 address, which must be followed by “/” and a prefix length;

  • a host name which resolves to an IPv4 address.

Note that host names that resolve to IPv6 addresses are not supported.

The physical interface name is the network interface name.

The value for the optional default router is specified similarly to the network address except that it must not be followed by a / (slash) and a network prefix length. To enable correct use of the defrouter functionality, the zones that use the property must be on a different subnet from the subnet on which the global zone resides. Also, each zone (or set of zones) that uses a different defrouter setting must be on a different subnet.

A zone can be configured to be either exclusive-IP or shared-IP. For a shared-IP zone, you must set both the physical and address properties; setting the default router is optional. The interface specified in the physical property must be plumbed in the global zone prior to booting the non-global zone. However, if the interface is not used by the global zone, it should be configured down in the global zone, and the default router for the interface should be specified here.

For an exclusive-IP zone, the physical property must be set and the address and default router properties cannot be set. Note that a single datalink cannot be shared among multiple exclusive-IP zones.

device: match

Device name to match.

rctl: name, value

The name and priv/limit/action triple of a resource control. See prctl(1) and rctladm(1M). The preferred way to set rctl values is to use the global property name associated with a specific rctl.

attr: name, type, value

The name, type and value of a generic attribute. The type must be one of int, uint, boolean or string, and the value must be of that type. uint means unsigned , that is, a non-negative integer.

dataset: name

The name of a ZFS dataset to be accessed from within the zone. See zfs(1M).

global: cpu-shares

The number of Fair Share Scheduler (FSS) shares to allocate to this zone. This property is incompatible with the dedicated-cpu resource. This property is the preferred way to set the zone.cpu-shares rctl.

global: max-lwps

The maximum number of LWPs simultaneously available to this zone. This property is the preferred way to set the zone.max-lwps rctl.

global: max-msg-ids

The maximum number of message queue IDs allowed for this zone. This property is the preferred way to set the zone.max-msg-ids rctl.

global: max-sem-ids

The maximum number of semaphore IDs allowed for this zone. This property is the preferred way to set the zone.max-sem-ids rctl.

global: max-shm-ids

The maximum number of shared memory IDs allowed for this zone. This property is the preferred way to set the zone.max-shm-ids rctl.

global: max-shm-memory

The maximum amount of shared memory allowed for this zone. This property is the preferred way to set the zone.max-shm-memory rctl. A scale (K, M, G, T) can be applied to the value for this number (for example, 1M is one megabyte).

global: scheduling-class

Specifies the scheduling class used for processes running in a zone. When this property is not specified, the scheduling class is established as follows:

  • If the cpu-shares property or equivalent rctl is set, the scheduling class FSS is used.

  • If neither cpu-shares nor the equivalent rctl is set and the zone's pool property references a pool that has a default scheduling class, that class is used.

  • Under any other conditions, the system default scheduling class is used.

dedicated-cpu: ncpus, importance

The number of CPUs that should be assigned for this zone's exclusive use. The zone will create a pool and processor set when it boots. See pooladm(1M) and poolcfg(1M) for more information on resource pools. The ncpu property can specify a single value or a range (for example, 1-4) of processors. The importance property is optional; if set, it will specify the pset.importance value for use by poold(1M). If this resource is used, there must be enough free processors to allocate to this zone when it boots or the zone will not boot. The processors assigned to this zone will not be available for the use of the global zone or other zones. This resource is incompatible with both the pool and cpu-shares properties. Only a single instance of this resource can be added to the zone.

capped-memory: physical, swap, locked

The caps on the memory that can be used by this zone. A scale (K, M, G, T) can be applied to the value for each of these numbers (for example, 1M is one megabyte). Each of these properties is optional but at least one property must be set when adding this resource. Only a single instance of this resource can be added to the zone. The physical property sets the max-rss for this zone. This will be enforced by rcapd(1M) running in the global zone. The swap property is the preferred way to set the zone.max-swap rctl. The locked property is the preferred way to set the zone.max-locked-memory rctl.

capped-cpu: ncpus

Sets a limit on the amount of CPU time that can be used by a zone. The unit used translates to the percentage of a single CPU that can be used by all user threads in a zone, expressed as a fraction (for example, .75) or a mixed number (whole number and fraction, for example, 1.25). An ncpu value of 1 means 100% of a CPU, a value of 1.25 means 125%, .75 mean 75%, and so forth. When projects within a capped zone have their own caps, the minimum value takes precedence.

The capped-cpu property is an alias for zone.cpu-cap resource control and is related to the zone.cpu-cap resource control. See resource_controls(5).

The following table summarizes resources, property-names, and types:

resource          property-name   type
(global)          zonename        simple
(global)          zonepath        simple

                   swap            simple with scale
                   locked          simple with scale

capped-cpu        ncpus           simple

To further specify things, the breakdown of the complex property “value” of the “rctl” resource type, it consists of three name/value pairs, the names being “priv”, “limit” and “action”, each of which takes a simple value. The “name” property of an “attr” resource is syntactically restricted in a fashion similar but not identical to zone names: it must begin with an alphanumeric, and can contain alphanumerics plus the hyphen (-), underscore (_), and dot (.) characters. Attribute names beginning with “zone” are reserved for use by the system. Finally, the “autoboot” global property must have a value of “true“ or “false”.

Using Kernel Statistics to Monitor CPU Caps

Using the kernel statistics (kstat(3KSTAT)) module caps, the system maintains information for all capped projects and zones. You can access this information by reading kernel statistics (kstat(3KSTAT)), specifying caps as the kstat module name. The following command displays kernel statistics for all active CPU caps:

# kstat caps::'/cpucaps/'

A kstat(1M) command running in a zone displays only CPU caps relevant for that zone and for projects in that zone. See EXAMPLES.

The following are cap-related arguments for use with kstat(1M):


The kstat module.

project_caps or zone_caps

kstat class, for use with the kstat -c option.

cpucaps_project_id or cpucaps_zone_id

kstat name, for use with the kstat -n option. id is the project or zone identifier.

The following fields are displayed in response to a kstat(1M) command requesting statistics for all CPU caps.


In this usage of kstat, this field will have the value caps.


As described above, cpucaps_project_id or cpucaps_zone_id


Total time, in seconds, spent above the cap.


Total time, in seconds, spent below the cap.


Maximum observed CPU usage.


Number of threads on cap wait queue.


Current aggregated CPU usage for all threads belonging to a capped project or zone, in terms of a percentage of a single CPU.


The cap value, in terms of a percentage of a single CPU.


Name of the zone for which statistics are displayed.

See EXAMPLES for sample output from a kstat command.


The following options are supported:

-f command_file

Specify the name of zonecfg command file. command_file is a text file of zonecfg subcommands, one per line.

-z zonename

Specify the name of a zone. Zone names are case sensitive. Zone names must begin with an alphanumeric character and can contain alphanumeric characters, the underscore (_) the hyphen (-), and the dot (.). The name global and all names beginning with SUNW are reserved and cannot be used.


You can use the add and select subcommands to select a specific resource, at which point the scope changes to that resource. The end and cancel subcommands are used to complete the resource specification, at which time the scope is reverted back to global. Certain subcommands, such as add, remove and set, have different semantics in each scope.

zonecfg supports a semicolon-separated list of subcommands. For example:

# zonecfg -z myzone "add net; set physical=myvnic; end"

Subcommands which can result in destructive actions or loss of work have an -F option to force the action. If input is from a terminal device, the user is prompted when appropriate if such a command is given without the -F option otherwise, if such a command is given without the -F option, the action is disallowed, with a diagnostic message written to standard error.

The following subcommands are supported:

add resource-type (global scope)
add property-name property-value (resource scope)

In the global scope, begin the specification for a given resource type. The scope is changed to that resource type.

In the resource scope, add a property of the given name with the given value. The syntax for property values varies with different property types. In general, it is a simple value or a list of simple values enclosed in square brackets, separated by commas ([foo,bar,baz]). See PROPERTIES.


End the resource specification and reset scope to global. Abandons any partially specified resources. cancel is only applicable in the resource scope.

clear property-name

Clear the value for the property.


Commit the current configuration from memory to stable storage. The configuration must be committed to be used by zoneadm. Until the in-memory configuration is committed, you can remove changes with the revert subcommand. The commit operation is attempted automatically upon completion of a zonecfg session. Since a configuration must be correct to be committed, this operation automatically does a verify.

create [-F] [ -a path |-b | -t template]

Create an in-memory configuration for the specified zone. Use create to begin to configure a new zone. See commit for saving this to stable storage.

If you are overwriting an existing configuration, specify the -F option to force the action. Specify the -t template option to create a configuration identical to template, where template is the name of a configured zone.

Use the -a path option to facilitate configuring a detached zone on a new host. The path parameter is the zonepath location of a detached zone that has been moved on to this new host. Once the detached zone is configured, it should be installed using the “zoneadm attach” command (see zoneadm(1M)). All validation of the new zone happens during the attach process, not during zone configuration.

Use the -b option to create a blank configuration. Without arguments, create applies the Sun default settings.

delete [-F]

Delete the specified configuration from memory and stable storage. This action is instantaneous, no commit is necessary. A deleted configuration cannot be reverted.

Specify the -F option to force the action.


End the resource specification. This subcommand is only applicable in the resource scope. zonecfg checks to make sure the current resource is completely specified. If so, it is added to the in-memory configuration (see commit for saving this to stable storage) and the scope reverts to global. If the specification is incomplete, it issues an appropriate error message.

export [-f output-file]

Print configuration to standard output. Use the -f option to print the configuration to output-file. This option produces output in a form suitable for use in a command file.

help [usage] [subcommand] [syntax] [command-name]

Print general help or help about given topic.

info zonename | zonepath | autoboot | brand | pool | limitpriv
info [resource-type [property-name=property-value]*]

Display information about the current configuration. If resource-type is specified, displays only information about resources of the relevant type. If any property-name value pairs are specified, displays only information about resources meeting the given criteria. In the resource scope, any arguments are ignored, and info displays information about the resource which is currently being added or modified.

remove resource-type{property-name=property-value}(global scope)

In the global scope, removes the specified resource. The [] syntax means 0 or more of whatever is inside the square braces. If you want only to remove a single instance of the resource, you must specify enough property name-value pairs for the resource to be uniquely identified. If no property name-value pairs are specified, all instances will be removed. If there is more than one pair is specified, a confirmation is required, unless you use the -F option.

select resource-type {property-name=property-value}

Select the resource of the given type which matches the given property-name property-value pair criteria, for modification. This subcommand is applicable only in the global scope. The scope is changed to that resource type. The {} syntax means 1 or more of whatever is inside the curly braces. You must specify enough property -name property-value pairs for the resource to be uniquely identified.

set property-name=property-value

Set a given property name to the given value. Some properties (for example, zonename and zonepath) are global while others are resource-specific. This subcommand is applicable in both the global and resource scopes.


Verify the current configuration for correctness:

  • All resources have all of their required properties specified.

  • A zonepath is specified.

revert [-F]

Revert the configuration back to the last committed state. The -F option can be used to force the action.

exit [-F]

Exit the zonecfg session. A commit is automatically attempted if needed. You can also use an EOF character to exit zonecfg. The -F option can be used to force the action.


Example 1 Creating the Environment for a New Zone

In the following example, zonecfg creates the environment for a new zone. /usr/local is loopback mounted from the global zone into /opt/local. /opt/sfw is loopback mounted from the global zone, three logical network interfaces are added, and a limit on the number of fair-share scheduler (FSS) CPU shares for a zone is set using the rctl resource type. The example also shows how to select a given resource for modification.

example# zonecfg -z myzone3
my-zone3: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:myzone3> create
zonecfg:myzone3> set zonepath=/export/home/my-zone3
zonecfg:myzone3> set autoboot=true
zonecfg:myzone3> add fs
zonecfg:myzone3:fs> set dir=/usr/local
zonecfg:myzone3:fs> set special=/opt/local
zonecfg:myzone3:fs> set type=lofs
zonecfg:myzone3:fs> add options [ro,nodevices]
zonecfg:myzone3:fs> end
zonecfg:myzone3> add fs
zonecfg:myzone3:fs> set dir=/mnt
zonecfg:myzone3:fs> set special=/dev/dsk/c0t0d0s7
zonecfg:myzone3:fs> set raw=/dev/rdsk/c0t0d0s7
zonecfg:myzone3:fs> set type=ufs
zonecfg:myzone3:fs> end
zonecfg:myzone3> add inherit-pkg-dir
zonecfg:myzone3:inherit-pkg-dir> set dir=/opt/sfw
zonecfg:myzone3:inherit-pkg-dir> end
zonecfg:myzone3> add net
zonecfg:myzone3:net> set address=
zonecfg:myzone3:net> set physical=eri0
zonecfg:myzone3:net> end
zonecfg:myzone3> add net
zonecfg:myzone3:net> set address=
zonecfg:myzone3:net> set physical=eri0
zonecfg:myzone3:net> end
zonecfg:myzone3> add net
zonecfg:myzone3:net> set address=
zonecfg:myzone3:net> set physical=eri0
zonecfg:myzone3:net> end
zonecfg:my-zone3> set cpu-shares=5
zonecfg:my-zone3> add capped-memory
zonecfg:my-zone3:capped-memory> set physical=50m
zonecfg:my-zone3:capped-memory> set swap=100m
zonecfg:my-zone3:capped-memory> end
zonecfg:myzone3> exit

Example 2 Creating a Non-Native Zone

The following example creates a new Linux zone:

example# zonecfg -z lxzone
lxzone: No such zone configured
Use 'create' to begin configuring a new zone
zonecfg:lxzone> create -t SUNWlx
zonecfg:lxzone> set zonepath=/export/zones/lxzone
zonecfg:lxzone> set autoboot=true
zonecfg:lxzone> exit

Example 3 Creating an Exclusive-IP Zone

The following example creates a zone that is granted exclusive access to bge1 and bge33000 and that is isolated at the IP layer from the other zones configured on the system.

The IP addresses and routing is configured inside the new zone using sysidtool(1M).

example# zonecfg -z excl
excl: No such zone configured
Use 'create' to begin configuring a new zone
zonecfg:excl> create
zonecfg:excl> set zonepath=/export/zones/excl
zonecfg:excl> set ip-type=exclusive
zonecfg:excl> add net
zonecfg:excl:net> set physical=bge1
zonecfg:excl:net> end
zonecfg:excl> add net
zonecfg:excl:net> set physical=bge33000
zonecfg:excl:net> end
zonecfg:excl> exit

Example 4 Associating a Zone with a Resource Pool

The following example shows how to associate an existing zone with an existing resource pool:

example# zonecfg -z myzone
zonecfg:myzone> set pool=mypool
zonecfg:myzone> exit

For more information about resource pools, see pooladm(1M) and poolcfg(1M).

Example 5 Changing the Name of a Zone

The following example shows how to change the name of an existing zone:

example# zonecfg -z myzone
zonecfg:myzone> set zonename=myzone2
zonecfg:myzone2> exit

Example 6 Changing the Privilege Set of a Zone

The following example shows how to change the set of privileges an existing zone's processes will be limited to the next time the zone is booted. In this particular case, the privilege set will be the standard safe set of privileges a zone normally has along with the privilege to change the system date and time:

example# zonecfg -z myzone
zonecfg:myzone> set limitpriv="default,sys_time"
zonecfg:myzone2> exit

Example 7 Setting the zone.cpu-shares Property for the Global Zone

The following command sets the zone.cpu-shares property for the global zone:

example# zonecfg -z global
zonecfg:global> set cpu-shares=5
zonecfg:global> exit

Example 8 Using Pattern Matching

The following commands illustrate zonecfg support for pattern matching. In the zone flexlm, enter:

zonecfg:flexlm> add device
zonecfg:flexlm:device> set match="/dev/cua/a00[2-5]"
zonecfg:flexlm:device> end

In the global zone, enter:

global# ls /dev/cua
a     a000  a001  a002  a003  a004  a005  a006  a007  b

Example 9 Setting a Cap for a Zone to Three CPUs

The following sequence uses the zonecfg command to set the CPU cap for a zone to three CPUs.

zonecfg:myzone> add capped-cpu
zonecfg:myzone>capped-cpu> set ncpus=3
zonecfg:myzone>capped-cpu>capped-cpu> end

The preceding sequence, which uses the capped-cpu property, is equivalent to the following sequence, which makes use of the zone.cpu-cap resource control.

zonecfg:myzone> add rctl
zonecfg:myzone:rctl> set name=zone.cpu-cap
zonecfg:myzone:rctl> add value (priv=privileged,limit=300,action=none)
zonecfg:myzone:rctl> end

Example 10 Using kstat to Monitor CPU Caps

The following command displays information about all CPU caps.

# kstat -n /cpucaps/
