OpenSolaris Automated Installs Using JeOS and VirtualBox Environment
By ckamps on Oct 20, 2009
As part of the JeOS project's effort to spur an initial specification and experimental implementation of OpenSolaris base install profiles, I wanted to be able to easily generate from scratch installations in a VirtualBox environment hosted on my Mac OS X system. Since I needed only a headless, text oriented installation of OpenSolaris to run the Automated Installer's (AI's) install service, I used the 2009.06 JeOS prototype VM image as the platform for the AI install server.
While looking for a VirtualBox-based AI example, I found Chris Armes' blog, Configuring an auto install client / server setup using VirtualBox. (I've since ran into another example here and a bare metal example here). The primary difference between Chris' environment and the example below is that I started with the reduced JeOS installation of OpenSolaris as compared to a Live CD-based installation. I also ended up using development build 126 of OpenSolaris as compared to the 2009.06 release.
Starting with a greatly reduced installation of OpenSolaris for the AI server meant that I had to spend a fair amount of time troubleshooting missing dependencies that weren't an issue when starting with a Live CD-based installation. (I'll have to review my notes and do some more digging to see if any of those dependencies warrant filing of new bugs).
In addition to referring to Chris' and the other examples, I referred to the official Automated Installer documentation.
Here are the overall steps that I took to get this configuration up and running:
- Downloaded and Deployed JeOS Prototype to VirtualBox
- Installed Build 126 AI and AI ISO Image
- Configured the AI Server
- Created an Install Service
- Created an AI Client in VirtualBox
- Booted the AI Client and Installed OpenSolaris
Details of these steps follow.
1. Downloaded and Deployed JeOS Prototype to VirtualBox
- Deployed 2009.06 JeOS prototype VM image for VirtualBox.
- Customized the installation based on the Next Steps in the JeOS documentation:
- Streamlined the boot experience
- Upgraded to the latest development build, 2010.03 build 126
- Added a personal user ID with administrator privileges
- Set up password-based SSH access
- Defined static IP address for e1000g0 interface
2. Installed Build 126 AI and AI ISO Image
$ pfexec pkg install SUNWinstalladm-tools
Download the build 126 AI ISO image from Genunix:
3. Configured the AI Server
e1000g0 is my install server's external network interface while e1000g1 is a newly added internal network interface. The install clients will talk to the AI server via this internal interface.
In VirtualBox, defined a second network adapter for the install server VM. Set it to use the "Internal network" and restarted the VM.
Set up the hostname file for internal interface:
$ cat /etc/hostname.e1000g1
Added an entry for the internal network to the netmasks file:
$ cat /etc/netmasks
Configured and brought up the internal interface:
$ pfexec ifconfig e1000g1 inet 192.168.3.50 netmask 255.255.255.0 broadcast 192.168.3.0
$ pfexec ifconfig e1000g1 up
Checked the resulting interfaces:
$ ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1100843<UP,BROADCAST,RUNNING,MULTICAST,ROUTER,IPv4> mtu 1500 index 2
inet 192.168.2.10 netmask ffffff00 broadcast 192.168.2.255
e1000g1: flags=1100843<UP,BROADCAST,RUNNING,MULTICAST,ROUTER,IPv4> mtu 1500 index 3
inet 192.168.3.50 netmask ffffff00 broadcast 192.168.3.255
lo0: flags=2002000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL> mtu 8252 index 1
Enabled port forwarding:
$ pfexec routeadm -e ipv4-forwarding -u
Note that routing services are not enabled since we're using static routing:
Configuration Current Current
Option Configuration System State
IPv4 routing disabled disabled
IPv6 routing disabled disabled
IPv4 forwarding enabled enabled
IPv6 forwarding disabled disabled
Routing services "route:default ripng:default"
Enabled NAT to allow AI clients on the private network to access Internet-based package repositories (e.g. http://pkg.opensolaris.org/dev) and for any troubleshooting activity to access other systems on the 192.168.2.0 network.
Defined IP filter rules (wide open for now):
$ cat ipf.conf
pass in quick on e1000g0 all
pass out quick on e1000g0 all
pass in quick on e1000g1 all
pass out quick on e1000g1 all
Applied IP filter to network interfaces:
$ cat pfil.ap
e1000g -1 0 pfil
Defined NAT mapping:
$ cat ipnat.conf
map e1000g0 192.168.3.0/24 -> 192.168.2.10/32 portmap tcp/udp 10000:65000
map e1000g0 192.168.3.0/24 -> 192.168.2.10/32
Ensured IP filter service was online:
$ pfexec svcadm enable ipfilter
$ svcs -a | grep ipfilter
online 14:26:27 svc:/network/ipfilter:default
Ensured IP filter rules were loaded:
$ pfexec ipf -Fa -f /etc/ipf/ipf.conf
$ pfexec ipfstat -ionh
32 @1 pass out quick on e1000g0 all
0 @2 pass out quick on e1000g1 all
62 @1 pass in quick on e1000g0 all
0 @2 pass in quick on e1000g1 all
Enabled multicast service:
$ pfexec svcadm enable dns/multicast
$ pfexec svcs -a | grep dns/multicast
online 15:50:08 svc:/network/dns/multicast:default
Enabled inetd service:
$ pfexec svcadm enable /network/inetd:default
$ pfexec svcs -a | grep inetd:default
online 17:02:19 svc:/network/inetd:default
Since the AI server requires a DHCP service and the DHCP service needs Java, installed the JRE:
$ pfexec pkg install SUNWj6rt
4. Created an Install Service
Listed the install clients in the hosts file:
$ cat /etc/hosts
192.168.2.10 opensolaris opensolaris.local loghost
Created the install service for these clients:
$ pfexec installadm create-service -n 1002-126-x86 -i 192.168.3.60 -c 4 -s /export/aiimages/osol-1002-126-ai-x86.iso /export/aiserver/osol-1002-126-ai-x86
$ installadm list
The install services running on the system are:
Ensured DHCP server was set up properly:
$ pfexec /usr/sbin/dhtadm -M -m 192.168.3.0 -e Router=192.168.3.50 -g
$ pfexec dhtadm -P

At this stage I pretty much followed the instructions in steps 9, 10 and 11 of Chris' blog entry.
The main difference is that I customized the default AI manifest to point at the development repository, http://pkg.opensolaris.org/dev, rather than the default release repository. See the How to Replace the Default AI Manifest documentation for details on this process.
Caution: When I ran the following command to replace the default manifest:
$ pfexec /usr/sbin/installadm add -m new-default.xml -n 1002-126-x86
I had expected the following file to have been updated:
But that's not the case. It seems as though that file is a reference default file and the real default file in use by the install service is housed under:
/var/ai/<install service port number>/AI_data/default.xml
The lack of any overt feedback from the installadm command and not seeing any change to the other default.xml file led me to believe that something had failed.
By default the AI installation will yield a desktop installation of OpenSolaris. In the next blog entry I've described how to use a custom manifest to install a greatly reduced, text-based headless server installation of OpenSolaris using this JeOS and VirtualBox-based AI environment.
