Step 1. Download the following files/directories...

bin/
catpages/
cdrom.inf
compat1x/
compat22/
compat3x/
compat4x/
crypto/
dict/
doc/
games/
info/
manpages/
proflibs/

from:

ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/old-releases/i386/4.9-RELEASE/

NOTE: For example, download those files/directories to /usr/repos/FreeBSD-4.9/4.9-RELEASE

Step 2. Download my "jail_build" script from:

http://druidbsd.sourceforge.net/download.shtml#jail_build

Step 3: Run jail_build

NOTE: If you put your downloaded files in /usr/repos/FreeBSD-4.9/4.9-RELEASE then jail_build will automatically find them and present 4.9 as an option. After selecting FreeBSD-4.9, it will then prompt you to enter the root directory where to unpack the jail to.

When jail_build completes, you'll have a freshly unpacked FreeBSD-4.9 in the desired root directory.

Step 4: Grab and install my vimage package:

http://druidbsd.sourceforge.net/download.shtml#vimage
About: http://druidbsd.sourceforge.net/vimage.shtml

Step 5: Configure your vimage in /etc/rc.conf (see /etc/rc.conf.d/vimage for a sample).

Example:

vimage_enable="YES"
vimage_list="fbsd4_9"
vimage_fbsd4_9_rootdir="/usr/jails/fbsd4_9"
vimage_fbsd4_9_hostname="fbsd4_9"
vimage_fbsd4_9_bridges="bge0"
vimage_fbsd4_9_devfs_enable="YES"
vimage_fbsd4_9_procfs_enable="YES"

Step 6: [Pre-]configure the network interface for the visage

Example:

chroot /usr/jails/fbsd4_9 vi /etc/rc.conf

NOTE: Since the vimage (aka vnet jail) isn't running yet, we use chroot instead of jexec. (Also note that the chroot is only for pedantic safety ... it prevents things such as "what if /etc/rc.conf is a symlink to /etc/rc.conf.other -- without the chroot you'd accidentally edit the host machines /etc/rc.conf.other).

Add the following:

ifconfig_ng0_fbsd4_9="inet 192.168.1.123 netmask 255.255.255.0"
defaultrouter="192.168.1.1"

# or whatever fits your network

# Don't forget /etc/resolv.conf

# Don't forget to set sshd_enable="YES" in rc.conf(5) if you want to be able to ssh into the vimage

Step 7: Fix some binaries in the 4.9 distribution to work under the 8.3 kernel...

Download my "update411binaries.sh" script (should work fine for 4.9 jails too) from...

http://druidbsd.sf.net/download/update411binares.sh

Step 8: Run update411binares.sh with a first argument of (for example) /usr/jails/fbsd4_9

Step 9: Fire up the vimage

service vimage start fbsd4_9

Step 10: Check things out...

jls

ssh 192.168.1.123

jexec fbsd4_9 csh

etc. etc.
