How to create an Olive (Juniper router) root-file-system for VNX

The procedure described here is mainly based on the excellent information provided in the following GNS3 blog entry: Olive reloaded or how to emulate Juniper routers. It has been tested over an Ubuntu 10.04.1 LTS machine.

Steps:

• Create the base root filesystem image (use 5G instead of 4G):

qemu-img create -f qcow2 root_fs_olive.qcow2 5G

• Download Freebsd 4.11 installation CD from:

wget ftp://ftp-archive.freebsd.org/pub/FreeBSD-Archive/old-releases/i386/ISO-IMAGES/4.11/4.11-RELEASE-i386-miniinst.iso

• Start the new virtual machine:

kvm -m 256 -hda root_fs_olive.qcow2 -cdrom 4.11-RELEASE-i386-miniinst.iso -boot d -localtime

and make the FreeBSD installation following the exact steps described in GNS3 blog.

• Once the FreeBSD installation is finished, stop the virtual machine (just make a Ctrl-C on the window you started the kvm command line when asked to restart). Start the virtual machine again using the following options:

kvm -m 1024 -hda root_fs_olive.qcow2 -boot c -localtime -net nic,macaddr=00:aa:00:60:01:01,model=e1000 -net user

• Login into the machine and configure the network interface:

dhclient em0

• Get JunOS package (you need an account in Juniper's server to download JunOS images):

wget ... jinstall-9.5R1.8-domestic-signed.tgz

• Copy it using scp from inside the virtual machine:

scp 10.0.2.2:/path-to/jinstall-9.5R1.8-domestic-signed.tgz /var/tmp

• Prepare the JunOS package before installing it using the following instructions:

cd /var/tmp
mkdir jinst-signed
cd jinst-signed/
tar zxvf ../jinstall-9.5R1.8-domestic-signed.tgz
mkdir jinst
cd jinst
tar zfvx ../jinstall-9.5R1.8-domestic.tgz
mkdir pkgtools
cd pkgtools
tar zxvf ../pkgtools.tgz
cd bin
cp /usr/bin/true ./checkpic
cd ..
tar zcvf ../pkgtools.tgz *
cd ..
rm -rf pkgtools
tar zcfv /var/tmp/jinstall-9.5R1.8-domestic-olive.tgz *
cd /var/tmp
rm -rf jinstall-9.5R1.8-domestic-signed.tgz jinst-signed

Note: you don't need to sign the package before rebuilding it as described in Olive's blogs. We've tested it

• Install the package:

pkg_add -f jinstall-9.5R1.8-domestic-olive.tgz

• When the installation is finished and you are required to reboot, stop the virtual machine with "halt" and restart it with the following parameters:

kvm -bios bios-0.10.6.bin -m 1024 -hda root_fs_olive.qcow2 -boot c -localtime -nodefaults -nographic -serial stdio

Note: as stated in an answer to "Olive reloaded" blog entry, olive virtual machines do not work with the latest BIOS distributed with qemu-kvm package. To make it work, you have to download the BIOS from qemu 0.10.6 version and copy it to /usr/share/qemu/ directory:

wget http://downloads.sourceforge.net/project/kvm/qemu-kvm/0.10.6/qemu-kvm-0.10.6.tar.gz
tar xfvz qemu-kvm-0.10.6.tar.gz
cp qemu-kvm-0.10.6/pc-bios/bios.bin /usr/share/qemu-kvm/bios-0.10.6.bin

• Finally, install the autoconfiguration daemon with the following procedure:
• Start the virtual machine with:

kvm -bios bios-0.10.6.bin -m 1024 -hda root_fs_olive.qcow2 -boot c -localtime -nodefaults -nographic -serial stdio -net nic,macaddr=00:aa:00:60:01:01,model=e1000 -net user

• Configure the network interface manually (dhclient is no more available; it has been deleted duting JunOS installation) and test the connectivity to the host:

ifconfig em0 inet 10.0.2.10/24
ping 10.0.2.2

• Copy the olived tar file to the virtual machine (note that name of the file could be different depending on the version):

scp 10.0.2.2:/usr/share/vnx/ace/vnx-ace-olive-0.1b.tgz /var/tmp

• Expand the tar file and install the daemon:

cd /var/tmp
tar xfvz vnx-ace-olive-0.1b.tgz 
cd vnx-ace-olive-0.1b
sh install-vnxolived

• Delete /var/tmp directory:

rm -rf /var/tmp/*

• Set the root password for the router:

cli
config
set system root-authentication plain-text-password 
commit

• Stop the virtual machine with a halt. The root filesystem is now ready to be used with VNX.
