How to add a zone in Solaris

With the introduction of the new Solaris OS 9/10 a hot new feature was the Virtualization. And the Solaris virtualization use a concept called zones. In this post I'm about to describe how to configure a zone in Solaris OS. In order to configure, it is needed to be installed Solaris OS on the server so called Global zone.

creating a zone

* gather = zonename and zonepath
* dedicate cpu resource or capped cpu resource

1.) To create the role and assign the role to a user "solaris Management tools
with RBAC" in Basic administration guide

2.) Setup a zone configuration with a zone name (eg: my-zone)

#zonecfg -z my-zone

will get an error if the first time and ask to create.

3.) create new zone configuration

zonecfg:my-zone> create

4.) set the zone path, /export/home/my-zone

zonecfg:my-zone> set zonepath=/export/home/my-zone
5.) set the autoboot value( set true to autoboot the zone) make sure
svc:/system/zones:default is enabled

zonecfg:my-zone> set autoboot=true
6.) Set persistent boot argument for a zone

zonecfg:my-zone> set bootargs="-m verbose"

7.) Dedicated one CPU to this zone

zonecfg:my-zone> add dedicated-cpu

a. Set the number of CPUs.

zonecfg:my-zone:dedicated-cpu> set ncpus=1-2

b. (Optional) Set the importance.

zonecfg:my-zone:dedicated-cpu> set importance=10
The default is 1

c. End the cpecification

zonecfg:my-zone:dedicated-cpu> end

8.) Revised the default set of privileges

zonecfg:my-zone> set limitpriv="default,sys_time"

This line adds the ability to set the system clock to the default set of privileges.

9.) Set the scheduling class to FSS.

zonecfg:my-zone> set scheduling-class=FSS

10.) Add a memory cap.

zonecfg:my-zone> add capped-memory

a. Set the memory cap.

zonecfg:my-zone:capped-memory> set physical=50m

b. Set the swap memory cap.

zonecfg:my-zone:capped-memory> set swap=100m

c. Set the locked memory cap.

zonecfg:my-zone:capped-memory> set locked=30m

d. End the memory cap specification.

zonecfg:my-zone:capped-memory> end

11.) Add a file system.

zonecfg:my-zone> add fs

a. Set the mount point for the file system,/usr/local in this procedure.

zonecfg:my-zone:fs> set dir=/usr/local

b. Specify that/opt/zones/my-zone/local in the global zone is to be mounted as /usr/local
in the zone being configured.

zonecfg:my-zone:fs> set special=/opt/zones/my-zone/local

In the non-global zone, the/usr/local file system will be readable and writable.

c. Specify the file system type,lofs in this procedure.

zonecfg:my-zone:fs> set type=lofs

The type indicates how the kernel interacts with the file system.

d. End the file system specification.

zonecfg:my-zone:fs> end

12.) This step can be performed more than once to add more than one file system.
(Optional) Set the hostid.

zonecfg:my-zone> set hostid=80f0c086

13.) Add a ZFS dataset named sales in the storage pool tank.

zonecfg:my-zone> add dataset

a. Specify the path to the ZFS data set sales.

zonecfg:my-zone> set name=tank/sales

b. End the data set specification.

zonecfg:my-zone> end
