System Administration Guide: Virtualization Using the Solaris Operating System

Resource and Property Types

The resource and property types are described as follows:

Zone name

The zone name identifies the zone to the configuration utility. The following rules apply to zone names:

  • Each zone must have a unique name.

  • A zone name is case-sensitive.

  • A zone name must begin with an alphanumeric character.

    The name can contain alphanumeric characters, underbars (_), hyphens (-), and periods (.).

  • The name cannot be longer than 64 characters.

  • The name global and all names beginning with SUNW are reserved and cannot be used.


The zonepath property is the path to the zone root. Each zone has a path to its root directory that is relative to the global zone's root directory. At installation time, the global zone directory is required to have restricted visibility. It must be owned by root with the mode 700.

The non-global zone's root path is one level lower. The zone's root directory has the same ownership and permissions as the root directory (/) in the global zone. The zone directory must be owned by root with the mode 755. These directories are created automatically with the correct permissions, and do not need to be verified by the zone administrator. This hierarchy ensures that unprivileged users in the global zone are prevented from traversing a non-global zone's file system.

See Traversing File Systems for a further discussion of this issue.

Note –

You can move a zone to another location on the same system by specifying a new, full zonepath with the move subcommand of zoneadm. See Moving a Non-Global Zone for instructions.


If this property is set to true, the zone is automatically booted when the global zone is booted. Note that if the zones service, svc:/system/zones:default is disabled, the zone will not autoboot, regardless of the setting of this property. You can enable the zones service with the svcadm command described in the svcadm(1M) man page:

global# svcadm enable zones

This property is used to set a boot argument for the zone. The boot argument is applied unless overridden by the reboot, zoneadm boot, or zoneadm reboot commands. See Branded Zone Boot Arguments.


This property is used to associate the zone with a specific resource pool on the system. Multiple zones can share the resources of one pool. Also see Specifying the dedicated-cpu Resource.


This property is used to specify a privilege mask other than the default. See Privileges in a Non-Global Zone.

Privileges are added by specifying the privilege name, with or without the leading priv_. Privileges are excluded by preceding the name with a dash (-) or an exclamation mark (!). The privilege values are separated by commas and placed within quotation marks ().

As described in priv_str_to_set(3C), the special privilege sets of none, all, and basic expand to their normal definitions. Because zone configuration takes place from the global zone, the special privilege set zone cannot be used. Because a common use is to alter the default privilege set by adding or removing certain privileges, the special set default maps to the default, set of privileges. When default appears at the beginning of the limitpriv property, it expands to the default set.

The following entry adds the ability to set the system clock and removes the ability to send raw Internet Control Message Protocol (ICMP) packets:

global# zonecfg -z userzone
zonecfg:userzone> set limitpriv="default,sys_time,!net_icmpaccess"

If the zone's privilege set contains a disallowed privilege, is missing a required privilege, or includes an unknown privilege, an attempt to verify, ready, or boot the zone will fail with an error message.


This property sets the scheduling class for the zone. See Scheduling Class in a Zone for additional information and tips.


This resource dedicates a subset of the system's processors to the zone while it is running. The dedicated-cpu resource provides limits for ncpus and, optionally, importance. For more information, seeSpecifying the dedicated-cpu Resource.


This resource establishes an absolute limit on the number of CPUs for this zone. The capped-cpu resource provides limits for ncpus. For more information, seeSpecifying the capped-cpu Resource.


This resource groups the properties used when capping memory for the zone. The capped-memory resource provides limits for physical, swap, and locked memory. At least one of these properties must be specified.


Each zone can have various file systems that are mounted when the zone transitions from the installed state to the ready state. The file system resource specifies the path to the file system mount point. For more information about the use of file systems in zones, see File Systems and Non-Global Zones.


The network interface resource is the interface name. Each zone can have network interfaces that are be set up when the zone transitions from the installed state to the ready state.

Only the shared-IP network configuration is supported in an lx branded zone


The rctl resource is used for zone-wide resource controls. The controls are enabled when the zone transitions from the installed state to the ready state.

Note –

To configure zone-wide controls using the set global_property_name subcommand of zonefig instead of the rctl resource, see How to Configure the lx Branded Zone.


This generic attribute can be used for user comments or by other subsystems. The name property of an attr must begin with an alphanumeric character. The name property can contain alphanumeric characters, hyphens (-), and periods (.). Attribute names beginning with zone. are reserved for use by the system.
