About Live Zone Reconfiguration of Kernel Zones

Use Live Zone Reconfiguration to perform the following tasks on a running kernel zone:

  • Report on and inspect the current live zone configuration

  • Make temporary changes in the live zone configuration

  • Apply changes made in the persistent configuration to the live zone configuration

Use the zonecfg and zoneadm commands to administer Live Zone Reconfiguration. You can make temporary or persistent changes to the zone configuration. Temporary changes are active until the next reboot. You do not need to reboot for changes to be applied to the persistent configuration.

Services are available within the zone with no downtime when you make the following configuration changes:

  • Changing resource controls

  • Changing network configuration

  • Changing the CPU resource pool

  • Changing the memory size

  • Adding or removing file systems

  • Adding or removing virtual and physical devices

For a list of supported resource types and properties during live zone reconfiguration, see Live Zone Reconfiguration Support or Restriction for Resource Types and Global Properties in Oracle Solaris Zones Configuration Resources.
