'''NOTE''': VNX is known to (basically) work with other libvirt versions like 0.8.5 and 0.8.8. However, as some problems have been detected with that versions and our present development and testing platform uses libvirt 0.9.3, we strongly recommend to use that version.

work with other 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.

'''IMPORTANT NOTE''': Windows XP virtual machines started with VNX over Ubuntu 9.10 frequently hang when executing commands or with high traffic loads. The problem could be related with virtual network drivers. We are investigating the problem to find a solution. By now, Ubuntu 10.04 is the recomended platform to test VNX.

VNX Installation over Ubuntu

This section describes the procedure for manually installing VNX over Ubuntu 12.04, 12.10 and 13.04.

Open a root shell window and follow these steps:

  • Install all packages required (basic development, virtualization, perl libraries and auxiliar packages):
  • sudo apt-get update
    sudo apt-get install 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 libterm-readline-perl-perl libnet-telnet-perl \
      libnet-ip-perl libreadonly-perl libmath-round-perl libappconfig-perl \
      libdbi-perl graphviz genisoimage gnome-terminal tree libio-pty-perl libsys-virt-perl \
      libfile-homedir-perl curl w3m picocom expect lxc
  • Tune libvirt configuration to work with VNX. In particular, edit /etc/libvirt/qemu.conf file and set the following parameters:
  • security_driver = "none"
    user = "root"
    group = "root"
    cgroup_device_acl = [
       "/dev/null", "/dev/full", "/dev/zero",
       "/dev/random", "/dev/urandom",
       "/dev/ptmx", "/dev/kvm", "/dev/kqemu",
       "/dev/rtc", "/dev/hpet", "/dev/net/tun",

    and restart libvirtd for the changes to take effect:

    restart libvirt-bin
  • Check that libvirt is running correctly, for example, executing:
  • virsh list
    virsh capabilities

    Note: Have a look at this document in case you get an error similar to this one: virsh: /usr/lib/libvirt.so.0: version LIBVIRT_PRIVATE-XXX not found (required by virsh)

  • Install VNX:
  • mkdir /tmp/vnx-update
    cd /tmp/vnx-update
    rm -rf /tmp/vnx-update/vnx-*
    wget http://vnx.dit.upm.es/vnx/vnx-latest.tgz
    tar xfvz vnx-latest.tgz
    cd vnx-*
  • Create the VNX config file (/etc/vnx.conf). You just can move the sample config file:
  • mv /usr/share/vnx/etc/vnx.conf.sample /etc/vnx.conf
  • 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:
    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/R3640.net
    console R3640     # type 'no' to exit the config wizard and wait 
                  # for the router to completely start 
    idlepc get R3640
    Once you know the idlepc value for your system, include it in /etc/vnx.conf file.
