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 

Note: for Ubuntu 9.04 change "qemu-kvm" package by "qemu kvm"

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

 apt-get install ia32-libs

• Install libvirt 0.7.5:

 /etc/init.d/libvirt-bin stop
 wget http://libvirt.org/sources/libvirt-0.7.5.tar.gz
 tar xfvz libvirt-0.7.5.tar.gz
 cd libvirt-0.7.5
 ./configure --without-xen --prefix=/usr && make && make install
 /etc/init.d/libvirt-bin start

NOTE: By now, libvirt 0.7.5 is the only version of libvirt known to work with VNX.

NOTE2: libvirt 0.7.5 is available as a package in Ubuntu 10.04. However 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 it 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/filesystem

# 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-gui-10.04-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
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").
