Installing VNUML over Fedora 7/8

This HowTo describes how to install VNUML over a fresh Fedora 7/8 installation. Note that it is a preliminary version. Let us know if it does not work for you.

Installation steps:

  1. Install Fedora 7/8 and make sure basic development tools are installed. Use the following command to install them if needed:
  2. yum groupinstall "Development Tools"
  3. Update the system with:
  4. yum update
  5. Install the following packages needed by VNUML:
  6. yum install bridge-utils readline-devel perl-Module-Build screen expat-devel libpcap-devel perl-Net-Pcap perl-NetAddr-IP perl-Net-IPv6Addr perl-XML-DOM perl-Exception-Class perl-TermReadKey perl-Error perl-CPAN
  7. Install uml_utilities:
  8. wget http://www.user-mode-linux.org/~blaisorblade/uml-utilities/uml_utilities_20060323.tar.bz2
    tar xfvj uml_utilities_20060323.tar.bz2
    cd tools-20060323
    make install
  9. Installl VNUML. Dowload latest vnuml tar file from http://www.dit.upm.es/vnumlwiki/index.php/Download and:
  10. tar xfvz  vnuml_1.8.3.orig.tar.gz
    cd vnuml-1.8.3
    ./configure --with-build_modules --prefix="/usr"
    make install   # answer NO when asked about manual configuration; 
                   # answer YES when asked "Shall I follow them and prepend....")
  11. Install VNUML kernel. Download "linux-um" package from VNUML site and:
  12.  cd /usr/share
     tar xfvz linux-um_2.6.18.1-bb2-xt-4m.orig.tar.gz
     ln -s linux-um- linux-um 
     mv linux-um/linux- /usr/share/vnuml/kernels
     ln -s /usr/share/vnuml/kernels/linux- /usr/share/vnuml/kernels/linux
  13. Install root_fs using root-fs-instaler installer script:
  14.  cd /usr/share/vnuml/filesystems
     wget http://www.dit.upm.es/vnuml/download/scripts/root-fs-installer
     perl root-fs-installer
  15. Create ssh keys with:
  16.  ssh-keygen -t rsa1
  17. Test the installation with:
  18.  cd /usr/share/vnuml/examples:
     vnumlparser.pl -t simple.xml -v -u root

Important note:

If you use kernel or older, do not use <consoles> with id=0 (use id="1" instead). For example, edit your scenarios and change:

   <console id="0">xterm</console>


   <console id="1">xterm</console>

If you use console id="0" the scenarios will start and work normally, but the virtual machines will hang when stopping the scenario using "-d" option. See https://lists.dit.upm.es/pipermail/vnuml-users/2007-September/000664.html for more details.

In any case, it is strongly recommended to update to the latests kernel version to avoid this problem.
