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 python-dev libsasl2-dev
  • If you use 64 bits version of Ubuntu, install 32 bits compatibility libraries:
  •  apt-get install ia32-libs
  • Install libvirt 0.9.3:
  •  /etc/init.d/libvirt-bin stop
     tar xfvz libvirt-0.9.3.tar.gz
     cd libvirt-0.9.3
     ./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:
  • Install VNX:
  • mkdir /tmp/vnx-update
    cd /tmp/vnx-update
    wget -N
    tar xfvz vnx-latest.tgz
    cd 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 and copy them to /usr/share/vnx/filesystems directory:
  • cd /usr/share/vnx/filesystems
    # ubuntu server
    wget -N
    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
    bunzip2 root_fs_ubuntu-10.10-gui-v01.qcow2.bz2
    ln -s root_fs_ubuntu-10.10-gui-v01.qcow2 root_fs_ubuntu-gui
    # freebsd server
    wget -N
    bunzip2 root_fs_freebsd-8.1-v01.qcow2.bz2
    ln -s root_fs_freebsd-8.1-v01.qcow2 root_fs_freebsd
    # freebsd gui
    wget -N
    bunzip2 root_fs_freebsd-8.1-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
    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
    chmod +x linux-
    ln -s linux- 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
# Start/stop the dynamips program as a daemon.
# Provides:          dynamips
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Cisco hardware emulator daemon

DESC="Cisco Emulator"

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_of_proc -p $PIDFILE $DAEMON $NAME && exit 0 || exit $? 
        #status $NAME
*)      log_action_msg "Usage: $SCRIPTNAME {start|stop|restart|status}"
        exit 2
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
dynagen /usr/share/vnx/examples/
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:
