Zone configuration consists of a number of resources and properties. .sp .LP To simplify the user interface, \fBzonecfg\fR uses the concept of a scope. The default scope is global. .sp .LP The following synopsis of the \fBzonecfg\fR command is for interactive usage: .sp .in +2 .nf zonecfg \fB-z\fR \fIzonename subcommand\fR .fi .in -2 .sp .sp .LP Parameters changed through \fBzonecfg\fR do not affect a running zone. The zone must be rebooted for the changes to take effect. .sp .LP In addition to creating and modifying a zone, the \fBzonecfg\fR utility can also be used to persistently specify the resource management settings for the global zone. .sp .LP In the following text, "rctl" is used as an abbreviation for "resource control". See \fBresource_controls\fR(5). .sp .LP 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 \fBzonecfg\fR properties and resources. See the brand-specific man page for more details on each brand. For an overview of brands, see the \fBbrands\fR(5) man page. .SS "Resources" .sp .LP The following resource types are supported: .sp .ne 2 .mk .na \fB\fBattr\fR\fR .ad .sp .6 .RS 4n Generic attribute. .RE .sp .ne 2 .mk .na \fB\fBcapped-cpu\fR\fR .ad .sp .6 .RS 4n Limits for CPU usage. .RE .sp .ne 2 .mk .na \fB\fBcapped-memory\fR\fR .ad .sp .6 .RS 4n Limits for physical, swap, and locked memory. .RE .sp .ne 2 .mk .na \fB\fBdataset\fR\fR .ad .sp .6 .RS 4n \fBZFS\fR dataset. .RE .sp .ne 2 .mk .na \fB\fBdedicated-cpu\fR\fR .ad .sp .6 .RS 4n Subset of the system's processors dedicated to this zone while it is running. .RE .sp .ne 2 .mk .na \fB\fBdevice\fR\fR .ad .sp .6 .RS 4n Device. .RE .sp .ne 2 .mk .na \fB\fBfs\fR\fR .ad .sp .6 .RS 4n file-system .RE .sp .ne 2 .mk .na \fB\fBinherit-pkg-dir\fR\fR .ad .sp .6 .RS 4n 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.

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. .SS "Sparse Root Zones" .sp .LP Non-global zones that have \fBinherit-pkg-dir\fR resources are called sparse root zones. .sp .LP The sparse root zone model optimizes the sharing of objects in the following ways: .RS +4 .TP .ie t \(bu .el o Only a subset of the packages installed in the global zone are installed directly into the non-global zone. .RE .RS +4 .TP .ie t \(bu .el o Read-only loopback file systems, identified as \fBinherit-pkg-dir\fR resources, are used to gain access to other files. .RE .sp .LP 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. .RS +4 .TP .ie t \(bu .el o As a general guideline, a zone requires about 100 megabytes of free disk space per zone when the global zone has been installed with all of the standard Solaris packages. .RE .RS +4 .TP .ie t \(bu .el o By default, any additional packages installed in the global zone also populate the non-global zones. The amount of disk space required might be increased accordingly, depending on whether the additional packages deliver files that reside in the \fBinherit-pkg-dir\fR resource space. .RE .sp .LP An additional 40 megabytes of RAM per zone are suggested, but not required on a machine with sufficient swap space. .sp .LP A sparse zone inherits the following directories: .sp .in +2 .nf /lib /platform /sbin /usr .fi .in -2 .sp .sp .LP Although \fBzonecfg\fR 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. .sp .LP Adding an additional \fBinherit-pkg-dir\fR directory, such as \fB/opt\fR, to a sparse root zone is acceptable. .SS "Whole Root Zones" .sp .LP 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. .sp .LP The disk requirements for this model are determined by the disk space used by the packages currently installed in the global zone. .LP Note - .sp .RS 2 If you create a sparse root zone that contains the following \fBinherit-pkg-dir\fR directories, you must remove these directories from the non-global zone's configuration before the zone is installed to have a whole root zone: .RS +4 .TP .ie t \(bu .el o \fB/lib\fR .RE .RS +4 .TP .ie t \(bu .el o \fB/platform\fR .RE .RS +4 .TP .ie t \(bu .el o \fB/sbin\fR .RE .RS +4 .TP .ie t \(bu .el o \fB/usr\fR .RE .RE .SS "Properties" .sp .LP Each resource type has one or more properties.

The type allowed is property-specific. Simple values are strings, optionally enclosed within quotation marks. Complex values have the syntax: .sp .in +2 .nf (<\fIname\fR>=<\fIvalue\fR>,<\fIname\fR>=<\fIvalue\fR>,...) .fi .in -2 .sp .sp .LP where each <\fIvalue\fR> is simple, and the <\fIname\fR> strings are unique within a given property. Lists have the syntax: .sp .in +2 .nf [<\fIvalue\fR>,...] .fi .in -2 .sp .sp .LP where each <\fIvalue\fR> 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 "[]"). .sp .LP In interpreting property values, \fBzonecfg\fR accepts regular expressions as specified in \fBfnmatch\fR(5). See \fBEXAMPLES\fR. .sp .LP The property types are described as follows: .sp .ne 2 .mk .na \fBglobal: \fBzonename\fR\fR .ad .sp .6 .RS 4n The name of the zone. .RE .sp .ne 2 .mk .na \fBglobal: \fBzonepath\fR\fR .ad .sp .6 .RS 4n Path to zone's file system. .RE .sp .ne 2 .mk .na \fBglobal: \fBautoboot\fR\fR .ad .sp .6 .RS 4n 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 \fBsvcadm\fR command, such as: .sp .in +2 .nf # \fBsvcadm enable svc:/system/zones:default\fR .fi .in -2 .sp Replace \fBenable\fR with \fBdisable\fR to disable the zones service. See \fBsvcadm\fR(1M). .RE .sp .ne 2 .mk .na \fBglobal: \fBbootargs\fR\fR .ad .sp .6 .RS 4n Arguments (options) to be passed to the zone bootup, unless options are supplied to the "\fBzoneadm boot\fR" command, in which case those take precedence. The valid arguments are described in \fBzoneadm\fR(1M). .RE .sp .ne 2 .mk .na \fBglobal: \fBpool\fR\fR .ad .sp .6 .RS 4n Name of the resource pool that this zone must be bound to when booted. This property is incompatible with the \fBdedicated-cpu\fR resource. .RE .sp .ne 2 .mk .na \fBglobal: \fBlimitpriv\fR\fR .ad .sp .6 .RS 4n 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 \fBpriv_str_to_set\fR(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 \fBzones\fR(5). A missing or empty property is equivalent to this same set of safe privileges. .sp 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. \fBzoneadm\fR(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. .sp See \fBprivileges\fR(5) for a description of privileges. The command "\fBppriv -l\fR" (see \fBppriv\fR(1)) produces a list of all Solaris privileges. You can specify privileges as they are displayed by \fBppriv\fR. In \fBprivileges\fR(5), privileges are listed in the form PRIV_\fIprivilege_name\fR. For example, the privilege \fIsys_time\fR, as you would specify it in this property, is listed in \fBprivileges\fR(5) as \fBPRIV_SYS_TIME\fR. .RE .sp .ne 2 .mk .na \fBglobal: \fBbrand\fR\fR .ad .sp .6 .RS 4n The zone's brand type. .RE .sp .ne 2 .mk .na \fBglobal: \fBip-type\fR\fR .ad .sp .6 .RS 4n A zone can either share the IP instance with the global zone, which is the default, or have its own exclusive instance of IP. .sp This property takes the values \fBshared\fR and \fBexclusive\fR. .RE .sp .ne 2 .mk .na \fBglobal: \fBhostid\fR\fR .ad .sp .6 .RS 4n A zone can emulate a 32-bit host identifier to ease system consolidation. A zone's \fBhostid\fR 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 \fB0x\fR or \fB0X\fR prefix is optional. Both uppercase and lowercase hexadecimal digits are acceptable. .RE .sp .ne 2 .mk .na \fB\fBfs\fR: dir, special, raw, type, options\fR .ad .sp .6 .RS 4n Values needed to determine how, where, and so forth to mount file systems.

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 \fBdown\fR in the global zone, and the default router for the interface should be specified here. .sp For an exclusive-IP zone, the physical property must be set and the address and default router properties cannot be set. .RE .sp .ne 2 .mk .na \fB\fBdevice\fR: match\fR .ad .sp .6 .RS 4n Device name to match. .RE .sp .ne 2 .mk .na \fB\fBrctl\fR: name, value\fR .ad .sp .6 .RS 4n The name and \fIpriv\fR/\fIlimit\fR/\fIaction\fR triple of a resource control. See \fBprctl\fR(1) and \fBrctladm\fR(1M).

This property is the preferred way to set the \fBzone.max-shm-memory\fR rctl. A scale (K, M, G, T) can be applied to the value for this number (for example, 1M is one megabyte). .RE .sp .ne 2 .mk .na \fBglobal: \fBscheduling-class\fR\fR .ad .sp .6 .RS 4n Specifies the scheduling class used for processes running in a zone. When this property is not specified, the scheduling class is established as follows: .RS +4 .TP .ie t \(bu .el o If the \fBcpu-shares\fR property or equivalent rctl is set, the scheduling class FSS is used. .RE .RS +4 .TP .ie t \(bu .el o If neither \fBcpu-shares\fR 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. .RE .RS +4 .TP .ie t \(bu .el o Under any other conditions, the system default scheduling class is used. .RE .RE .sp .ne 2 .mk .na \fB\fBdedicated-cpu\fR: ncpus, importance\fR .ad .sp .6 .RS 4n 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 \fBpooladm\fR(1M) and \fBpoolcfg\fR(1M) for more information on resource pools. The \fBncpu\fR property can specify a single value or a range (for example, 1-4) of processors. The \fBimportance\fR property is optional; if set, it will specify the \fBpset.importance\fR value for use by \fBpoold\fR(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 \fBpool\fR and \fBcpu-shares\fR properties. Only a single instance of this resource can be added to the zone. .RE .sp .ne 2 .mk .na \fB\fBcapped-memory\fR: physical, swap, locked\fR .ad .sp .6 .RS 4n 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 \fBphysical\fR property sets the \fBmax-rss\fR for this zone. This will be enforced by \fBrcapd\fR(1M) running in the global zone. The \fBswap\fR property is the preferred way to set the \fBzone.max-swap\fR rctl. The \fBlocked\fR property is the preferred way to set the \fBzone.max-locked-memory\fR rctl. .RE .sp .ne 2 .mk .na \fB\fBcapped-cpu\fR: ncpus\fR .ad .sp .6 .RS 4n 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, \fB\&.75\fR) or a mixed number (whole number and fraction, for example, \fB1.25\fR). An \fBncpu\fR value of \fB1\fR means 100% of a CPU, a value of \fB1.25\fR means 125%, \fB\&.75\fR mean 75%, and so forth. When projects within a capped zone have their own caps, the minimum value takes precedence. .sp The \fBcapped-cpu\fR property is an alias for \fBzone.cpu-cap\fR resource control and is related to the \fBzone.cpu-cap\fR resource control.

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 (\fB-\fR), underscore (\fB_\fR), and dot (\fB\&.\fR) 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". .SS "Using Kernel Statistics to Monitor CPU Caps" .sp .LP Using the kernel statistics (\fBkstat\fR(3KSTAT)) module \fBcaps\fR, the system maintains information for all capped projects and zones.
