Resource Type Properties in the lx Branded Zone

Resources also have properties to configure. The following properties are associated with the resource types shown.

dedicated-cpu

ncpus, importance

Specify the number of CPUs and, optionally, the relative importance of the pool. The following example specifies a CPU range for use by the zone lx-zone. importance is also set.

zonecfg:lx-zone> add dedicated-cpu zonecfg:lx-zone:dedicated-cpu> set ncpus=1-3 zonecfg:lx-zone:dedicated-cpu> set importance=2 zonecfg:lx-zone:dedicated-cpu> end

capped-cpu

ncpus

Specify the number of CPUs. The following example specifies a CPU limit of 3.5 CPUs for use by the zone lx-zone.

zonecfg:lx-zone> add capped-cpu zonecfg:lx-zone:capped-cpu> set ncpus=3.5 zonecfg:lx-zone:capped-cpu> end

capped-memory

physical, swap, locked

This resource groups the properties used when capping memory for the zone. The following example specifies the memory limits for the zone lx-zone. Each limit is optional, but at least one must be set.

zonecfg:my-zone> add capped-memory zonecfg:lx-zone:capped-memory> set =50m zonecfg:lx-zone:capped-memory> set swap=100m zonecfg:lx-zone:capped-memory> set locked=30m zonecfg:lx-zone:capped-memory> end

fs

dir, special, raw, type, options

The lines in the following example add read-only access to CD or DVD media in a non-global zone. The file system is loopback mounted with the options ro,nodevices (read-only and no devices) in the non-global zone.

zonecfg:lx-zone> add fs zonecfg:lx-zone:fs> set dir=/cdrom zonecfg:lx-zone:fs> set special=/cdrom zonecfg:lx-zone:fs> set type=lofs zonecfg:lx-zone:fs> add options [ro,nodevices] zonecfg:lx-zone:fs> end

Note that section 1M man pages are available for mount options that are unique to a specific file system. The names of these man pages have the form mount_filesystem.

net

address, physical

In the following example, IP address 192.168.0.1 is added to a zone. An bge0 card is used for the physical interface.

zonecfg:lx-zone> add net zonecfg:lx-zone:net> set physical=bge0 zonecfg:lx-zone:net> set address=192.168.0.1 zonecfg:lx-zone:net> end

---

Note –

To determine which physical interface to use, type ifconfig -a on your system. Each line of the output, other than loopback driver lines, begins with the name of a card installed on your system. Lines that contain LOOPBACK in the descriptions do not apply to cards.

---

rctl

name, value

Available zone-wide resource controls are described in Zone-Wide Resource Controls in an lx Branded Zone.

zonecfg:lx-zone> add rctl zonecfg:lx-zone:rctl> set name=zone.cpu-shares zonecfg:lx-zone:rctl> add value (priv=privileged,limit=10,action=none) zonecfg:lx-zone:rctl> end

zonecfg:lx-zone> add rctl zonecfg:lx-zone:rctl> set name=zone.max-lwps zonecfg:lx-zone:rctl> add value (priv=privileged,limit=100,action=deny) zonecfg:lx-zone:rctl> end

attr

name, type, value

In the following example, a comment about a zone is added.

zonecfg:lx-zone> add attr zonecfg:lx-zone:attr> set name=comment zonecfg:lx-zone:attr> set type=string zonecfg:lx-zone:attr> set value="Production zone" zonecfg:lx-zone:attr> end

You can use the export subcommand to print a zone configuration to standard output. The configuration is saved in a form that can be used in a command file.
