New Solaris Zones Features

The following Solaris Zones enhancements are found in the Solaris 10 10/08 release:

• Update on Attach – If the new host has the same or later versions of the zone-dependent packages and their associated patches, using zoneadm attach with the -u option, updates those packages within the zone to match the new host. If the new host has a mixture of higher and lower version packages and patches as compared to the source host, then an update during the attach operation is not allowed. This option also enables automatic migration between machine classes, such as from sun4u to sun4v.

  For more information, see the zoneadm(1M) man page and System Administration Guide: Solaris Containers-Resource Management and Solaris Zones.

• Ability to Set Default Router in Shared-IP Zone – A defrouter property has been added to the net resource in the zonecfg utility for shared-IP non-global zones. You can set the default router for the network interface through this property.

  For more information, see the zonecfg(1M) man page and System Administration Guide: Solaris Containers-Resource Management and Solaris Zones.

• ZFS Zone Path Permitted – Starting with the Solaris 10 10/08 release, the zonepath can be on ZFS and the system can be upgraded. For a zone with the zonepath on ZFS, only Solaris Live Upgrade can be used to upgrade the system. For more information, see System Administration Guide: Solaris Containers-Resource Management and Solaris Zones.
