Suse10.2

Installing VNUML over Open Suse 10.2

Important note:

There is a problem with vnuml 1.7.3 in Suse related with vnumlize functionality. The parser hangs after printing: Checking for the skas3 patch in the host: - /proc/mm...not found - PTRACE_FAULTINFO...not found - PTRACE_LDT...not found UML running in SKAS0 mode To avoid the problem, just type "crtl-C" afert the above message or better use the "-Z" option to disable vnumlize functionallity: vnumlparser.pl -t simple.xml -v -u root -Z This problem does not happen with vnuml 1.8 version.

Installation steps:

1. Install "bridge-utilities" which is available from Yast2
2. Download uml-utilities from here and install them:

rpm -i uml-utilities-20040406-35.i586.rpm

3. Install the following perl modules from CPAN using this command:

 perl -MCPAN -e "install Net::Pcap; install Module::Build; install Net::IPv6Addr; force install NetAddr::IP"

Note: basic c/c++ development tools (gcc, make, etc) must be installed for this step to work.

4. Download the latest version of vnuml parser from VNUML site and install it:

 tar xfvz vnuml_1.7.3.orig.tar.gz
 cd vnuml-1.7.3
 ./configure --with-build_modules
 make
 make install    (Note: answer "NO" if asked "Are you ready for manual configuration?")

5. Download root filesystem (root_fs_tutorial-0.4.1.bz2) from VNUML site and:

 cp root_fs_tutorial-0.4.1.bz2 /usr/local/share/vnuml/filesystems
 cd /usr/local/share/vnuml/filesystems
 bunzip2 root_fs_tutorial-0.4.1.bz2
 ln -s root_fs_tutorial-0.4.1 root_fs_tutorial  

6. Download guest kernel (linux-2.6.16.27-bs2-xt-1m.tar.bz2) from VNUML site and:

 mkdir /usr/local/share/vnuml/kernels/src
 cp linux-2.6.16.27-bs2-xt-1m.tar.bz2 /usr/local/share/vnuml/kernels/src
 cd /usr/local/share/vnuml/kernels/src
 tar xfvj linux-2.6.16.27-bs2-xt-1m.tar.bz2
 cp linux-2.6.16.27-bs2-xt-1m/linux-2.6.16.27-bs2-xt-1m ..
 cd ..
 ln -s linux-2.6.16.27-bs2-xt-1m linux

7. Create ssh key:

ssh-keygen -t rsa1

8. Installation is finished. Test simple.xml example to see if everything works:

 vnumparser.pl -t /usr/local/share/vnuml/examples/simple.xml -v -u root -Z

Note: if you execute the example from a "root" session, you should add the option "-u root" at the end of the line. There are some pending bugs that prevent a simulation to work when executed as "vnuml" user (the default when you do not use -u option) from a root session.
