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

Installation

Installing on 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




• 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:

wget -N http://www.dit.upm.es/vnx/download/vnx-0.14b.tgz
tar xfvz vnx-0.14b.tgz
cd vnx-0.14b
./install_vnx

• 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-10.04-v01.qcow2.bz2
bunzip2 root_fs_ubuntu-10.04-v01.qcow2.bz2
ln -s root_fs_ubuntu-10.04-v01.qcow2 root_fs_ubuntu

# ubuntu with gui
wget -N http://idefix.dit.upm.es/download/vnx/filesystems/root_fs_ubuntu-10.04-gui-v01.qcow2.bz2
bunzip2 root_fs_ubuntu-10.04-gui-v01.qcow2.bz2
ln -s root_fs_ubuntu-10.04-gui-v01.qcow2 root_fs_ubuntu-gui

# freebsd server
wget -N http://idefix.dit.upm.es/download/vnx/filesystems/root_fs_freebsd-v01.qcow2.bz2
bunzip2 root_fs_freebsd-v01.qcow2.bz2
ln -s root_fs_freebsd-v01.qcow2 root_fs_freebsd

# freebsd gui
wget -N http://idefix.dit.upm.es/download/vnx/filesystems/root_fs_freebsd-gui-v01.qcow2.bz2
bunzip2 root_fs_freebsd-gui-v01.qcow2.bz2
ln -s root_fs_freebsd-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/filesystem
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

Installing on Fedora 11 (Not completed yet)

Follow tis steps to install VNX over Fedora 11:

• Instalar VNUML sobre Fedora 11 siguiendo la receta en http://www.dit.upm.es/vnumlwiki/index.php/Fedora11
• Instalar paquetes y librerías necesarias:

yum install qemu-kvm libvirt virt-manager virt-viewer perl-XML-LibXML perl-Sys-Virt
yum -y install bridge-utils readline-devel perl-Module-Build screen expat-devel libpcap-devel  
yum -y install perl-Net-Pcap perl-NetAddr-IP perl-Net-IPv6Addr perl-XML-DOM perl-Exception-Class
yum -y install perl-TermReadKey perl-Error perl-CPAN uml_utilities xterm tunctl

• Install XML::Checker perl library:

perl -MCPAN -e shell
install XML::Checker

• Add symbolic link for kvm:

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

• Instalar VNX:

wget -N http://idefix.dit.upm.es/download/vnx/vnx-0.12b.tgz
tar xfvz vnx-0.12b.tgz
cd vnx-0.12b
./install-vnx

• Deshabilitar el firewall o, alternativamente, configurar los interfaces tipo "tun" como confiables (Sistema->Firewall->Interfaces Confiables").

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

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

/etc/init.d/dynamips start
dynagen /usr/share/vnx/examples/R.net

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
