QUESTION

How can I set up and configure a Solaris 8 zone under Solaris 10?

surfaceANSWER
Zones are a feature new in Solaris 10, and provide a useful mechanism to create a Solaris environment  for testing, and containment (Apache server, etc.). No additional hardware is required for a zone, just some disk space. The impact of a zone on machine performance is minimal. as all zones use the same kernel, so some additional memory for extra processes is all that's required.
Resource allocation to a zone can be closely controlled, and this includes processor shares, resource pools and resource capping with rcapd.
Since update 4 of Solaris 10 (August 2007) dedicated network interfaces can be assigned to a zone; prior to this they have to be shared with the global zone.
Also, you can now download additional software from Sun to allow you to run Solaris 8 and 9 within a zone.
Here is an example of a Solaris 8 zone creation, but for a fuller picture consider attending our Solaris 10 Administration Part 2 course

Firstly, if needed, install patch 127127-11 and reboot your system. (Check with showrev -p as it may already be installed)

Now obtain and install the required software package from Sun - this is s8containers-bundle-solaris10-sparc.tar.gz which can be downloaded here.
# gunzip  s8containers-bundle-solaris10-sparc.tar.gz
# tar  xvf  s8containers-bundle-solaris10-sparc.tar
Create a suitable directory, to hold the zone copy of the  OS:-

# cd  s8containers-bundle/1.0/Product
Install all the packages in this directory with pkgadd:-
# pkgadd  -d  .
  1  SUNWs8brandr     Solaris 8 Containers: solaris8 brand support (Root)
                      (sparc) 11.10.0,REV=2007.10.08.16.51
  2  SUNWs8brandu     Solaris 8 Containers: solaris8 brand support (Usr)
                      (sparc) 11.10.0,REV=2007.10.08.16.51
  3  SUNWs8p2v        Solaris 8 p2v Tool
                      (sparc) 11.10.0,REV=2007.10.08.16.51

Select package(s) you wish to process (or 'all' to process
all packages). (default: all) [?,??,q]: all
etc etc..

Now the zone can be configured:-
# mkdir  -p /Zones/sol8
# zonecfg -z sol8
sol8: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:sol8> create  -t   SUNWsolaris8
zonecfg:sol8> set zonepath=/Zones/sol8
zonecfg:sol8> set autoboot=true
zonecfg:sol8> add  net
zonecfg:sol8:net> set   physical=eri0
zonecfg:sol8:net> set address=192.168.200.155
zonecfg:sol8:net> end
zonecfg:sol8> add  attr
zonecfg:sol8:attr> set name=hostid
zonecfg:sol8:attr> set type=string
zonecfg:sol8:attr> set value=83685987
zonecfg:sol8:attr> end
zonecfg:sol8> verify
zonecfg:sol8> commit
zonecfg:sol8> exit
#
The above add attr section adds a hostid to the zone.

Now use zoneadm to install the zone:-
# zoneadm  -z sol8  install  -u  -a  /root/containers/solaris8-image.flar
-u causes the Solaris 8 zone to be installed in a sys-unconfig state, i.e. no hostname or name services configured.
Use -p instead if you want to preserve the Solaris 8 system's original ID.
-a /root/containers/solaris8-image.flar specifies the location of the flash archive to use.

The installtion continues:-
      Log File: /var/tmp/sol8.install.27972.log
        Source: /root/containers/solaris8-image.flar
    Installing: This may take several minutes...
Postprocessing: This may take several minutes...
        Result: Installation completed successfully.
      Log File: /Zones/sol8/root/var/log/sol8.install.27972.log
#
The zone can now be booted with zoneadm, but you may wish to install a sysidcfg file into the /etc directory of the zone before you do this; here is an example:-

locale=C
name_service=NONE
system_locale=C
network_interface=primary{protocol_ipv6=no hostname=sol8 netmask=255.255.255.0}
timezone=GB
terminal=xterm
timeserver=localhost
security_policy=none
root_password=pvDVrMdPynYk2   (Make sure this is a genuine envrypted password - you can copy one from your /etc/shadow file)

Now boot the new Solaris 8 zone:-
# zoneadm  -z  sol8  boot
# zlogin  -C  sol8
[Connected to zone 'sol8' console]
Configuring network interface addresses: eri0.
add default route: Not owner

We have now created the Solaris 8 zone, installed it, rebooted and logged in.
Use the usual commands to check things out (df, ifconfig, uname, etc).
Tips:  (But make sure your site security allows this)
1. Edit /etc/default/login and comment out the "CONSOLE=/dev/console" line to permit remote root logins. (password needed of course..)
2. Edit /etc/ssh/sshd_config and set PermitRootLogin=yes if you want to login as root via ssh. Restart sshd with "svcadm restart ssh"
3. Current zone implementation allows graphical login if the zone runs "dtlogin  -daemon" by default.
We hope this has been useful, see below for additional notes
