On Oracle Solaris 11.2, we have already seen that kernel zones are completely isolated from the global zone. Oracle Solaris 11.2 kernel zones support both backward and forwards compatibility which means you can also run Oracle Solaris 11.3(When it release) on the kernel zone where your global zone can still with oracle Solaris 11.2 In most of the Solaris 11 projects, they may have already deployed the traditional native zones(Whole root) and now maybe they are thinking that how to convert the whole root zones as kernel zones. For those who want to convert the existing native zone to a kernel zone, please follow the below procedure.
1. Login to the global zone and list the installed zones. Here we will convert WHOLEROOT zone(native) as the kernel zone.
root@UA-GLOBAL:/UAIPS# zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / solaris shared - UAKLZ1 installed - solaris-kz excl - WHOLEROOT installed /cloudS/WHOLEROOT solaris excl - UANEWZ1 installed /cloudS/UANEWZ1 solaris excl root@UA-GLOBAL:/UAIPS#
2. Here WHOLEROOT is the native zone. Create a unified archive for that local zone.
root@UA-GLOBAL:~# archiveadm create -z WHOLEROOT /UAIPS/WHOLEROOT.uar Unified Archive initialized: /UAIPS/WHOLEROOT.uar. Logging to: /system/volatile/archive_log.17649 Dataset discovery completey... Media creation completefor zone(s)... Archive stream creation completen... Archive creation completessembly... root@UA-GLOBAL:~#
3. Check the newly created unified archive information.
root@UA-GLOBAL:/UAIPS# ls -lrt /UAIPS/WHOLEROOT.uar
-rw-r--r-- 1 root root 1276774400 Aug 11 08:12 /UAIPS/WHOLEROOT.uar
root@UA-GLOBAL:/UAIPS# archiveadm info /UAIPS/WHOLEROOT.uar

5. Create a new kernel zone configuration using the below command.
root@UA-GLOBAL:/UAIPS# zonecfg -z UAKERZ2 create -t SYSsolaris-kz root@UA-GLOBAL:/UAIPS#
6. Make sure you have a minimum 16GB on the zone’s root path.
root@SAN:~# zonecfg -z UAKERZ2 info device
device:
match not specified
storage: dev:/dev/zvol/dsk/rpool/VARSHARE/zones/UAKERZ2/disk0
id: 0
bootpri: 0
root@SAN:~#
Note: Oracle Solaris kernel zones will not use ZFS dataset. It creates an emulated volume in ZFS that will act as a virtual disk. So there is no option to set the zone path. Instead of that, we have to set the device to install the kernel zone.
As per the above command output, this kernel zone will create a virtual disk under rpool. Let me modify it to another zpool since my rpool doesn’t have enough space to install it.
7. Here I am modifying the zone’s root disk path.
root@UA-GLOBAL:~# zonecfg -z UAKERZ2
zonecfg:UAKERZ2> select device id=0
zonecfg:UAKERZ2:device> set storage=dev:/dev/zvol/dsk/cloudS/UAKERZ2-disk0

8. Restore the whole root zone’s archive using the below command.

9. Once the zone installation is completed, just boot the zone and log in to the zone’s console for setting the hostname and IP address.
root@UA-GLOBAL:/UAIPS# zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / solaris shared - UAKLZ1 installed - solaris-kz excl - WHOLEROOT installed /cloudS/WHOLEROOT solaris excl - UANEWZ1 installed /cloudS/UANEWZ1 solaris excl - UAKERZ2 installed - solaris-kz excl root@UA-GLOBAL:/UAIPS# root@UA-GLOBAL:/UAIPS# zoneadm -z UAKERZ2 boot
10. Login to the zone’s console to complete the installation.
root@UA-GLOBAL:/UAIPS# zlogin -C UAKERZ2

We have successfully migrated the whole root zone(native) as oracle Solaris kernel zone using the unified archive. Kernel zones are very useful when you want to run the zone on its own patch level.
We have already seen the installation of the kernel zone using IPS repository. Feel free to check it.
