Oracle Solaris 11.2 kernel zones supports both backwards 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 may be they are thinking that how to convert the whole root zones as kernel zones. For those who want to convert existing native zone as 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 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 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

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

4. To know more about archive, use option -v.

5. Create a new kernel zone configuration using below command.
root@UA-GLOBAL:/UAIPS# zonecfg -z UAKERZ2 create -t SYSsolaris-kz
root@UA-GLOBAL:/UAIPS#
6. Make sure you have 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 and that will act as virtual disk. So there is no option to set the zonepath. Instead of that, we have to set 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 to other 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

bootpri: 0
zonecfg:UAKERZ2:device> end
zonecfg:UAKERZ2> commit
zonecfg:UAKERZ2> exit
root@UA-GLOBAL:~# zonecfg -z UAKERZ2 info device

8. Restore the wholeroot zone's archive using below command.
root@UA-GLOBAL:/UAIPS# zoneadm -z UAKERZ2 install -a /UAIPS/WHOLEROOT.uar

We have successfully migrated the whole root zone(native) as oracle Solaris kernel zone using unified archive . Kernel zones are very useful when you want to run the zone on its own patch level.
