VNX (Virtual Networks over X virtualization) v0.14 beta

Installation over Ubuntu 10.04/9.10

This section describes the procedure for installing VNX over Ubuntu 10.04 or 9.10. Open a root shell window and follow these steps:

Install all packages required (basic development, virtualization, perl libraries and auxiliar packages):

apt-get update
apt-get install build-essential qemu-kvm libvirt-bin vlan xterm \
  bridge-utils  screen virt-manager virt-viewer libxml-checker-perl \
  libxml-parser-perl libnetaddr-ip-perl libnet-pcap-perl \
  libnet-ipv6addr-perl liberror-perl libexception-class-perl \
  uml-utilities libxml-libxml-perl libxml2-dev libgnutls-dev \
  libdevmapper-dev libterm-readline-perl-perl libnet-telnet-perl \
  libnet-ip-perl libreadonly-perl libmath-round-perl libappconfig-perl \
  libdbi-perl graphviz libnl-dev genisoimage gnome-terminal libfile-homedir-perl

If you use 64 bits version of Ubuntu, install 32 bits compatibility libraries:

 apt-get install ia32-libs

Install libvirt 0.8.5:

 /etc/init.d/libvirt-bin stop
 wget http://libvirt.org/sources/libvirt-0.8.5.tar.gz
 tar xfvz libvirt-0.8.5.tar.gz
 cd libvirt-0.8.5
 ./configure --without-xen --prefix=/usr && make && make install
 /etc/init.d/libvirt-bin start

NOTE: VNX should work with libvirt versions from 0.7.5 to 0.8.5 (it has been mainly tested with 0.7.5 and 0.8.5). Note that, although libvirt 0.7.5 is available as a package in Ubuntu 10.04, it has some problems related with the Apparmor profiles configured for libvirt. If you disable Apparmor (with "/etc/init.d/apparmor stop"), VNX will work with libvirt 0.7.5 installed as package, however we recommend to download and compile version 0.8.5 as described above, in order to maintain Apparmor in your system.

Install Sys::Virt perl module:

For Ubuntu 10.04, just install the libsys-virt-perl package

apt-get install libsys-virt-perl

For Ubuntu 9.10, as Sys::Virt library is not available as a package, install it manually:

wget http://search.cpan.org/CPAN/authors/id/D/DA/DANBERR/Sys-Virt-0.2.3.tar.gz
tar xfvz Sys-Virt-0.2.3.tar.gz 
cd Sys-Virt-0.2.3
perl Makefile.PL
make install

Install VNX:

mkdir /tmp/vnx-update
cd /tmp/vnx-update
wget -N http://idefix.dit.upm.es/download/vnx/vnx-latest.tgz
tar xfvz vnx-latest.tgz
cd vnx-*
./install_vnx

Create the VNX config file (/etc/vnx.conf). You just can move the sample config file:

mv /etc/vnx.conf.sample /etc/vnx.conf

Download root file systems from http://idefix.dit.upm.es/download/vnx/filesystems and copy them to /usr/share/vnx/filesystems directory:

cd /usr/share/vnx/filesystems

# ubuntu server
wget -N http://idefix.dit.upm.es/download/vnx/filesystems/root_fs_ubuntu-10.10-v02.qcow2.bz2
bunzip2 root_fs_ubuntu-10.10-v02.qcow2.bz2
ln -s root_fs_ubuntu-10.10-v02.qcow2 root_fs_ubuntu

# ubuntu with gui
wget -N http://idefix.dit.upm.es/download/vnx/filesystems/root_fs_ubuntu-10.10-gui-v01.qcow2.bz2

ln -s root_fs_freebsd-8.1-gui-v01.qcow2 root_fs_freebsd-gui

# winxp and win7
# Sorry! Unfortunately for legal reasons we cannot distribute windows XP
# or Windows 7 root filesystems. See VNX documentation for detailed recipes
# to create these root fylesystems from scratch

Additionally, if you plan to use VNUML root filesystem:

# VNUML root_fs_tutorial and kernel
cd /usr/share/vnx/filesystems
wget -N http://idefix.dit.upm.es/download/vnx/filesystems/root_fs_tutorial-0.6.0.bz2
bunzip2 root_fs_tutorial-0.6.0.bz2
ln -s root_fs_tutorial-0.6.0 root_fs_tutorial
cd /usr/share/vnx/kernels
wget -N http://jungla.dit.upm.es/~vnx/download/kernels/linux-2.6.18.1-bb2-xt-4m
chmod +x linux-2.6.18.1-bb2-xt-4m
ln -s linux-2.6.18.1-bb2-xt-4m linux

NOTE for Ubuntu 10.04.1: It seems that an additional package has to be installed:

apt-get install kvm-pxe

Additional install steps for Dynamips support

Install Dynamips and Dynagen:

apt-get install dynamips dynagen

Create a file /etc/init.d/dynamips (taken from http://7200emu.hacki.at/viewtopic.php?t=2198):

#!/bin/sh
# Start/stop the dynamips program as a daemon.
#
### BEGIN INIT INFO
# Provides:          dynamips
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Cisco hardware emulator daemon
### END INIT INFO

DAEMON=/usr/bin/dynamips
NAME=dynamips
PORT=7200
PIDFILE=/var/run/$NAME.pid 
LOGFILE=/var/log/$NAME.log
DESC="Cisco Emulator"
SCRIPTNAME=/etc/init.d/$NAME

test -f $DAEMON || exit 0

. /lib/lsb/init-functions


case "$1" in
start)  log_daemon_msg "Starting $DESC " "$NAME"
        start-stop-daemon --start --chdir /tmp --background --make-pidfile --pidfile $PIDFILE --name $NAME --startas $DAEMON -- -H $PORT -l $LOGFILE
        log_end_msg $?
        ;;
stop)   log_daemon_msg "Stopping $DESC " "$NAME"
        start-stop-daemon --stop --quiet --pidfile $PIDFILE --name $NAME
        log_end_msg $?
        ;;
restart) log_daemon_msg "Restarting $DESC " "$NAME"
        start-stop-daemon --stop --retry 5 --quiet --pidfile $PIDFILE --name $NAME
        start-stop-daemon --start --chdir /tmp --background --make-pidfile --pidfile $PIDFILE --name $NAME --startas $DAEMON -- -H $PORT -l $LOGFILE
        log_end_msg $?
        ;;
status)
        status_of_proc -p $PIDFILE $DAEMON $NAME && exit 0 || exit $? 
        #status $NAME
        #RETVAL=$?
        ;; 
*)      log_action_msg "Usage: $SCRIPTNAME {start|stop|restart|status}"
        exit 2
        ;;
esac
exit 0

Set execution permissions for the script and add it to system start-up:

chmod +x /etc/init.d/dynamips
update-rc.d dynamips defaults
/etc/init.d/dynamips start

Download and install cisco IOS image:

 cd /usr/share/vnx/filesystems
 # Cisco image
 wget ... c3640-js-mz.124-19.image
 ln -s c3640-js-mz.124-19.image c3640

Calculate the idle-pc value for your computer following the procedure in http://dynagen.org/tutorial.htm:

dynagen /usr/share/vnx/examples/R.net
console R     # type 'no' to exit the config wizard and wait 
              # for the router to completely start 
idle-pc get R

Once you know the idle-pc value for your system, include it in /etc/vnx.conf file.

Additional install steps for Olive support

Several additional steps are needed to support Olive (Juniper) routers in VNX scenarios:

Download old qemu bios from 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

Installation over Fedora 11 (Draft)

Follow this steps to install VNX over Fedora 11:

Install packages:

yum -y groupinstall "Development Tools"
yum install qemu-kvm libvirt virt-manager virt-viewer perl-XML-LibXML
yum install perl-XML-DOM perl-NetAddr-IP perl-Readonly perl-TermReadKey
yum install perl-Net-Pcap perl-Net-IPv6Addr perl-Net-Telnet perl-Error
yum install perl-Exception-Class perl-ExtUtils-MakeMaker tunctl screen wget
yum install libxml2-devel gnutls-devel device-mapper-devel uml_utilities 
yum install roxterm xterm graphviz perl-AppConfig

Install libvirt 0.8.5:

/etc/init.d/libvirtd stop
wget http://libvirt.org/sources/libvirt-0.8.5.tar.gz
tar xfvz libvirt-0.8.5.tar.gz
cd libvirt-0.8.5
./configure --without-xen --prefix=/usr && make && make install
/etc/init.d/libvirtd start

Install SysVirt manually:

wget http://search.cpan.org/CPAN/authors/id/D/DA/DANBERR/Sys-Virt-0.2.4.tar.gz
tar xfvz Sys-Virt-0.2.4.tar.gz
cd Sys-Virt-0.2.4
perl Makefile.PL
make install

Add symbolic link for kvm:

ln -s /usr/bin/qemu-kvm /usr/bin/kvm

Install VNX:

mkdir /tmp/vnx-update
cd /tmp/vnx-update
wget -N http://idefix.dit.upm.es/download/vnx/vnx-latest.tgz
tar xfvz vnx-latest.tgz
cd vnx-*
./install_vnx

Create the VNX config file (/etc/vnx.conf). You just can move the sample config file:

mv /etc/vnx.conf.samble /etc/vnx.conf

Disable host firewall or, alternatively, configure "tun" type network interfaces as trusted interfaces (System->Firewall->Trusted Interfaces).
Download root file systems from http://idefix.dit.upm.es/download/vnx/filesystems and copy them to /usr/share/vnx/filesystems directory:

cd /usr/share/vnx/filesystems

+ rpm -i dynagen-0.11.0-1.fc9.noarch.rpm
+* Set execution permissions for the script and add it to system start-up:
+ chkconfig --add dynamips
+ /etc/init.d/dynamips start
+* Download and install cisco IOS image:
+  cd /usr/share/vnx/filesystems
+  # Cisco image
+  wget ... c3640-js-mz.124-19.image
+  ln -s c3640-js-mz.124-19.image c3640
+* Calculate the idle-pc value for your computer following the procedure in http://dynagen.org/tutorial.htm:
+ dynagen /usr/share/vnx/examples/R.net
+ console R     # type 'no' to exit the config wizard and wait
+               # for the router to completely start
+ idle-pc get R
+Once you know the idle-pc value for your system, include it in /etc/vnx.conf file.
