zoneadm - administer zones  


zoneadm -z zonename [-u uuid-match] subcommand 

zoneadm [-R root] [-z zonename] [-u uuid-match] list 

zoneadm [-R root] -z zonename [-u uuid-match] mark incomplete



The zoneadm utility is used to administer system zones. A zone is an application container that is maintained by the operating system runtime.  


Once a process has been placed in a zone other than zone 0, the process or any of its children cannot change zones.  


The following options are supported:

-R root

Specify an alternate root (boot environment). This option can only be used in conjunction with the "list" and "mark" subcommands.

-u uuid-match

Unique identifier for a zone, as assigned by libuuid(3LIB). If this option is present and the argument is a non-empty string, then the zone matching the UUID is selected instead of the one named by the -z option, if such a zone is present.

-z zonename

String identifier for a zone.



Subcommands which can result in destructive actions or loss of work have a -F flag to force the action. If input is from a terminal device, the user is prompted if such a command is given without the -F flag; otherwise, if such a command is given without the -F flag, the action is disallowed, with a diagnostic message written to standard error. If a zone installation or uninstallation is interrupted, the zone is left in the incomplete state. Use uninstall to reset such a zone back to the configured state.

The following subcommands are supported:

attach [-u] [-b patchid]... [-F] [-n path]

The attach subcommand takes a zone that has been detached from one system and attaches the zone onto a new system. Therefore, it is advised (though not required) that the detach subcommand should be run before the "attach" takes place. Once you have the new zone in the configured state, use the attach subcommand to set up the zone root instead of installing the zone as a new zone.

For native zones, zoneadm checks package and patch levels on the machine to which the zone is to be attached. If the packages/patches that the zone depends on from the global zone are different (have different revision numbers) from the dependent packages/patches on the source machine, zoneadm reports these conflicts and does not perform the attach. If the destination system has only newer dependent packages/patches (higher revision numbers) than those on the source system, you can use the -u option to update the attached zone to match the higher-revision packages and patches that exist on the new system. With -u, as in the default behavior, zoneadm does not perform an attach if outdated packages/patches are found on the target system.

For native zones, one or more -b options can be used to specify a patch ID for a patch installed in the zone. These patches will be backed out before the zone is attached or, if -u was also specified, updated.

The -F option can be used to force the zone into the "installed" state with no validation. This option should be used with care since it can leave the zone in an unsupportable state if it was moved from a source system to a target system that is unable to properly host the zone. The -n option can be used to run the attach subcommand, without executing the command. It uses the output of the "detach -n" subcommand as input and is useful to identify any conflicting issues, such as the network device being incompatible, and can also determine whether the host is capable of supporting the zone. The path can be "-", to read the input from standard input.

The zone being attached must first be configured using the zonecfg (see zonecfg(1M)) command. This does not apply when running "attach -n".

Use the following command to attach a zone:

# zoneadm -z my-zone attach

Use the following command to attach and update a zone:

# zoneadm -z my-zone attach -u

boot [-- boot_options]

Boot (or activate) the specified zones.

The following boot_options are supported:

-i altinit

Select an alternative executable to be the primordial Process. altinit is a valid path to an executable. The default primordial process is init(1M).

-m smf_options

The smf_options include two categories of options to control booting behavior of the service management facility: recovery options and messages options.

Message options determine the type and amount of messages that smf(5) displays during boot. Service options determine the services which are used to boot the system. See kernel(1M) for a listing of the -m suboptions.


Boots only to milestone svc:/milestone/single-user:default. This milestone is equivalent to init level s. See svc.startd(1M) and init(1M).

clone [-m copy] [-s zfs_snapshot] source_zone

Install a zone by copying an existing installed zone. This subcommand is an alternative way to install the zone.

-m copy

Force the clone to be a copy, even if a "ZFS clone" is possible.

-s zfs_snapshot

Specify the name of a ZFS snapshot to use as the source of the clone. The snapshot must be a snapshot of the source zone taken from a previous "zoneadm clone" installation.

The source zone must be halted before this subcommand can be used.

detach [-n]

Detach the specified zone. Detaching a zone is the first step in moving a zone from one system to another. The full procedure to migrate a zone is that the zone is detached, the zonepath directory is moved to the new host, and then the zone is attached on the new host. Once the zone is detached, it is left in the configured state. If you try to install or clone to a configured zone that has been detached, you will receive an error message and the install or clone subcommand will not be allowed to proceed. The -n option can be used to run the detach subcommand, without executing the command. This generates the information needed for running the "attach -n" subcommand, which is useful to identify any conflicting issues, such as the network device being incompatible or if the host is capable of supporting the zone. The information is sent to standard output and can be saved to a file or piped to the "attach -n" subcommand.

Use the following command to detach a zone:

# zoneadm -z my-zone detach 

The source zone must be halted before this subcommand can be used.


Halt the specified zones. halt bypasses running the shutdown scripts inside the zone. It also removes run time resources of the zone.


zlogin zone shutdown

to cleanly shutdown the zone by running the shutdown scripts.

help [subcommand]

Display general help. If you specify subcommand, displays help on subcommand.

install [-x nodataset] [brand-specific options]

Install the specified zone on the system. This subcommand automatically attempts to verify first. It refuses to install if the verify step fails. See the verify subcommand.

-x nodataset

Do not create a ZFS file system.

Branded zones may include additional options that govern how the brand's software will be installed in the zone. See brands(5) for specific brand information.

list [list_options]

Display the name of the current zones, or the specified zone if indicated.

By default, all running zones are listed. If you use this subcommand with the zoneadm -z zonename option, it lists only the specified zone, regardless of its state. In this case, the -i and -c options are disallowed.

If neither the -i or -c options are given, all running zones are listed.

The following list_options are supported:


Display all configured zones. This option overides the -i option.


Expand the display to all installed zones.


Request machine parsable output. The output format is a list of lines, one per zone, with colon- delimited fields. These fields are:


If the zonepath contains embedded colons, they can be escaped by a backslash (":"), which is parsable by using the shell read(1) function with the environmental variable IFS. The uuid value is assigned by libuuid(3LIB) when the zone is installed, and is useful for identifying the same zone when present (or renamed) on alternate boot environments. Any software that parses the output of the "zoneadm list -p" command must be able to handle any fields that may be added in the future.

The -v and -p options are mutually exclusive. If neither -v nor -p is used, just the zone name is listed.


Display verbose information, including zone name, id, current state, root directory, brand type, ip-type, and options.

The -v and -p options are mutually exclusive. If neither -v nor -p is used, just the zone name is listed.

mark incomplete

Change the state of an installed zone to "incomplete." This command may be useful in cases where administrative changes on the system have rendered a zone unusable or inconsistent. This change cannot be undone (except by uninstalling the zone).

move new_zonepath

Move the zonepath to new_zonepath. The zone must be halted before this subcommand can be used. The new_zonepath must be a local file system and normal restrictions for zonepath apply.


Prepares a zone for running applications but does not start any user processes in the zone.


Restart the zones. This is equivalent to a halt boot sequence. This subcommand fails if the specified zones are not active.

uninstall [-F]

Uninstall the specified zone from the system. Use this subcommand with caution. It removes all of the files under the zonepath of the zone in question. You can use the -F flag to force the action.


Check to make sure the configuration of the specified zone can safely be installed on the machine. Following is a break-down of the checks by resource/property type:


zonepath and its parent directory exist and are owned by root with appropriate modes . The appropriate modes are that zonepath is 700, its parent is not group or world-writable and so forth. zonepath is not over an NFS mount. A sub-directory of the zonepath named "root" does not exist.

If zonepath does not exist, the verify does not fail, but merely warns that a subsequent install will attempt to create it with proper permissions. A verify subsequent to that might fail should anything go wrong.

zonepath cannot be a symbolic link.


Any fs resources have their type value checked. An error is reported if the value is one of proc, mntfs, autofs, cachefs, or nfs or the filesystem does not have an associated mount binary at /usr/lib/fs/<fstype>/mount.

It is an error for the directory to be a relative path.

It is an error for the path specified by raw to be a relative path or if there is no fsck binary for a given filesystem type at /usr/lib/fs/<fstype>/fsck. It is also an error if a corresponding fsck binary exists but a raw path is not specified.


All physical network interfaces exist. All network address resources are one of:
o a valid IPv4 address, optionally followed by "/" and a prefix length;
o a valid IPv6 address, which must be followed by "/" and a prefix length;
o a host name which resolves to an IPv4 address.
Note that hostnames that resolve to IPv6 addresses are not supported.

The physical interface name is the network interface name.

A zone can be configured to be either exclusive-IP or shared-IP. For a shared-IP zone, both the physical and address properties must be set. For an exclusive-IP zone, the physical property must be set and the address property cannot be set.


It also verifies that any defined resource control values are valid on the current machine. This means that the privilege level is privileged, the limit is lower than the currently defined system value, and that the defined action agrees with the actions that are valid for the given resource control.



Example 1 Using the -m Option

The following command illustrates the use of the -m option.

# zoneadm boot -- -m verbose

Example 2 Using the -i Option

The following command illustrates the use of the -i option.

# zoneadm boot -- -i /sbin/init

Example 3 Using the -s Option

The following command illustrates the use of the -s option.

# zoneadm boot -- -s



The following exit values are returned:


Successful completion.


An error occurred.


Invalid usage.



See attributes(5) for descriptions of the following attributes:



Interface Stability



read(1), svcs(1), zlogin(1), zonename(1), init(1M), kernel(1M), svcadm(1M), svc.startd(1M), svc.startd(1M), zonecfg(1M), libuuid(3LIB), attributes(5), brands(5), smf(5), zones(5)  


The zones(5) service is managed by the service management facility, smf(5), under the service identifier:


Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.

The act of installing a new non-global zone is a fresh installation of the Solaris operating system. A new installation of Solaris must not require interaction with the user (that is, it must be "hands off"). Because of this, packages installed in the global zone and all non-global zones cannot contain request scripts (see pkgask(1M)). If a package did have a request script, then the creation of a non-global zone could not be done without user intervention. Any package that contains a request script is added to the global zone only. See pkgadd(1M).
