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 libnet-telnet-cisco-perl
  • 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:
  • 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").

  • Además hay que bajarse la bios de la 0.10 y copiarla al directorio :
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

Nota: otra forma de resolver el problema es usando la línea: 

<emulator>/usr/bin/kvm</emulator>

Se puede cambiar para que llame a un nuevo script kvm2 que llame al kvm original pero añadiendole la opcion "-bios biosfilename", pero para que funcione hay que parar el apparmor o añadirle una regla para que deje ejecutar ese nuevo script.


Instalación de ROM tarjetas de red

La versión de qemu-kvm que viene con Ubuntu 10.04 no trae la ROM pxe-i82559er.bin de las tarjetas de Olive (con las tarjetas e1000 no funciona). Hay que bajarse esa ROM de una distribución posterior de qemu-kvm: 

wget http://downloads.sourceforge.net/project/kvm/qemu-kvm/0.12.5/qemu-kvm-0.12.5.tar.gz
tar xfvz qemu-kvm-0.12.5.tar.gz
cp qemu-kvm-0.12.5/pc-bios/pxe-i82559er.bin /usr/share/qemu-kvm/
