Cloning a Non-Global Zone on the Same System

Cloning is used to provision a new zone on a system by copying the data from a source zonepath to a target zonepath.

When the source zonepath and the target zonepath both reside on ZFS and are in the same pool, the zoneadm clone command automatically uses ZFS to clone the zone. However, you can specify that the ZFS zonepath be copied and not ZFS cloned.

How to Clone a Zone

You must configure the new zone before you can install it. The parameter passed to the zoneadm create subcommand is the name of the zone to clone. This source zone must be halted.

You must be the global administrator or a user with appropriate authorizations in the global zone to perform this procedure.

  1. Become an administrator.
  2. Halt the source zone to be cloned, which is my-zone in this procedure.
    global# zoneadm -z my-zone halt
  3. Start configuring the new zone by exporting the configuration of the source zone my-zone to a file, for example, master.
    global# zonecfg -z my-zone export -f /zones/master

    Note - You can also create the new zone configuration using the procedure How to Configure the Zone instead of modifying an existing configuration. If you use this method, skip ahead to Step 6 after you create the zone.

  4. Edit the file master. Set different properties and resources for the components that cannot be identical for different zones. For example, you must set a new zonepath. For a shared-IP zone, the IP addresses in any net resources must be changed. For an exclusive-IP zone, the physical property of any net resource must be changed.
  5. Create the new zone, zone1, by using the commands in the file master.
    global# zonecfg -z zone1 -f /zones/master
  6. Install the new zone, zone1, by cloning my-zone.
    global# zoneadm -z zone1 clone my-zone

    The system displays:

    Cloning zonepath /zones/my-zone...
  7. List the zones on the system.
    ID  NAME     STATUS       PATH                           BRAND      IP
     0  global   running      /                              solaris    shared
     -  my-zone  installed    /zones/my-zone                 solaris    excl  
     -  zone1    installed    /zones/zone1                   solaris    excl  

Example 19-3 Applying a System Configuration Profile to a Cloned Zone

To include a configuration profile:

# zoneadm -z zone1 clone -c /path/config.xml my-zone

Note that you must provide an absolute path to the configuration file.
