VNX Installation over Fedora

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 tree

• 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 install them following these instructions

Additional install steps for Dynamips support

• Install Dynamips and Dynagen:

wget http://downloads.sourceforge.net/project/dyna-gen/dynamips%20Linux%20RPM/0.2.8-RC2/dynamips-0.2.8RC2-1.i386.rpm
rpm -i dynamips-0.2.8RC2-1.i386.rpm
wget http://downloads.sourceforge.net/project/dyna-gen/dynagen%20source%20_%20Linux/dynagen%200.11.0/dynagen-0.11.0-1.fc9.noarch.rpm
rpm -i dynagen-0.11.0-1.fc9.noarch.rpm

• Add dynamips to system start-up and start it manually for this time:

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.
