Zone Installation with AI
In the beginning of this lab we also mentioned that it's possible to install zones together with the host installation. It's time to learn how to do that.
First of all, we have to configure the zone we are going to install.
Let's create the simplest possible configuration with zonecfg(1M).
root@solarislab:~# zonecfg -z ai-zone create
This command creates a non-global zone with all default parameters. Now we have to export this configuration into a file:
root@solarislab:~# zonecfg -z ai-zone export -f ai-zone.cfg
Take a look at the resulting file:
root@solarislab:~# cat ai-zone.cfg create -b set brand=solaris set zonepath=/system/zones/%{zonename} set autoboot=false set autoshutdown=shutdown set ip-type=exclusive add anet set linkname=net0 set lower-link=auto set configure-allowed-address=true set link-protection=mac-nospoof set mac-address=auto end
Now we have to make it visible from the client we are about to install.
The best way to do it is to place it on a web server inside the local
network. Luckily, we have a running web server as part of the AI server
installation. We just have to configure the directory where to store
files on this web server. Let's use svccfg(1M) for that:
root@solarislab:~# svccfg -s svc:/system/install/server:default listprop (that means the directory is not configured yet) root@solarislab:~# mkdir /var/ai/ai-files root@solarislab:~# chown -R webservd:webservd /var/ai/ai-files/ root@solarislab:~# svccfg -s svc:/system/install/server:default setprop all_services/webserver_files_dir=/var/ai/ai-files root@solarislab:~# svccfg -s svc:/system/install/server:default listprop all_services/webserver_files_dir all_services/webserver_files_dir astring /var/ai/ai-files root@solarislab:~# svcadm refresh svc:/system/install/server:default
Now copy the zone configuration file to this place:
root@solarislab:~# cp ai-zone.cfg /var/ai/ai-files
Now, which file should we use to tell AI server to install the zone? What would be your guess? Of course, it's the manifest file! Everything that has to be installed is configured in the manifest! We will use the same XML file where we configured the Solaris version.
root@solarislab:~# vi s11.2.11-manifest.xml
Scroll down to the end. Insert the following line (marked bold) after
the software tag:
<software_data action="install">
<name>pkg:/entire@0.5.11-0.175.2.11.0.5.0</name>
<name>pkg:/group/system/solaris-small-server</name>
<name>pkg://solaris/system/management/puppet</name>
</software_data>
</software>
<configuration type="zone" name="ai-zone" source="http://10.80.11.34:5555/files/ai-zone.cfg"/>
</ai_instance>
</auto_install>
And, of course, after editing the XML file, don't forget to update the manifest:
root@solarislab:~# installadm update-manifest -n default-sparc -m s11.2.11 -f ./s11.2.11-manifest.xml
Now everything is ready. Once again login into the client domain and
perform the familiar procedure: halt the system (init 0) to get to
OpenBoot ok prompt, boot it from AI server (boot net - install).
Watch the messages on the screen. At some point you'll see the following
lines:
21:40:43 Zone name: ai-zone 21:40:43 source: http://10.80.11.34:5555/files/ai-zone.cfg
That means everything is good. Wait until the installation finishes, reboot and login into the client system. First, let's check if the zone is installed:
root@ai-client1:~# zoneadm list -cv ID NAME STATUS PATH BRAND IP 0 global running / solaris shared
Hmm... Nothing. Where is our zone? We were told it's going to be installed at the first boot! Let's investigate further. Check the status of the following service (it's responsible for zone installation):
root@ai-client1:~# svcs zones-install STATE STIME FMRI offline* 17:52:37 svc:/system/zones-install:default root@ai-client1:~# svcs -x svc:/system/zones-install:default (Zones auto-install) State: offline* transitioning to online since September 24, 2015 05:52:37 PM EDT Reason: Start method is running. See: http://support.oracle.com/msg/SMF-8000-C4 See: /var/svc/log/system-zones-install:default.log Impact: This service is not running.
Well, it's not running, but it's "transitioning to online". That's a good sign. Also we can take a look at its log file:
root@ai-client1:~# tail /var/svc/log/system-zones-install:default.log zoneadm: ai-zone: No such zone configured zoneadm: ai-zone: No such zone configured Configuring zone ai-zone Installing zone ai-zone zoneadm -z ai-zone install -m /usr/share/auto_install/manifest/zone_default.xml -c /usr/share/auto_install/sc_profiles/enable_sci.xml The following ZFS file system(s) have been created: rpool/VARSHARE/zones/ai-zone Progress being logged to /var/log/zones/zoneadm.20150924T215408Z.ai-zone.install Image: Preparing at /system/zones/ai-zone/root.
A-ha! Something is going on! It looks like our zone is being installed
right now. Check the default zonepath location:
root@ai-client1:~# ls /system/zones ai-zone
Indeed! The file system for the zone is created already. Check the log and the service again:

Great! It is installed. Now you can boot it, login via the console
(zlogin -C ai-zone), configure its profile and start using it. As you
might have guessed, you can configure the zone with manifests and system
profiles the same way we did it for AI clients. But we leave this
exercise for your homework.
