simple_ubuntu-gui.xml scenario
A simple scenario made of just one Ubuntu GUI virtual machine connected to a virtual network (Net0, 10.0.0.0/24), where the hosts has also a virtual network interface connected (10.0.0.1).
To start the scenario:
cd /usr/share/vnx/examples/ sudo vnx -f simple_ubuntu-gui.xml -v --create
Test the network connectivity from the host to the virtual machine:
# ping -c 4 10.0.0.1 PING 10.0.0.5 (10.0.0.5) 56(84) bytes of data. 64 bytes from 10.0.0.5: icmp_seq=1 ttl=64 time=0.197 ms
Start the calculator or the xeyes application on the virtual machine with:
sudo vnx -f simple_ubuntu-gui.xml -v --exe calc sudo vnx -f simple_ubuntu-gui.xml -v --exe xeyes
Close (kill) the calc application with:
sudo vnx -f simple_ubuntu-gui.xml -v --exe calcoff
Start or stop a web server in the virtual machine with:
sudo vnx -f /usr/share/vnx/examples/simple_ubuntu.xml -v --exe start-www sudo vnx -f /usr/share/vnx/examples/simple_ubuntu.xml -v --exe stop-www
Stop the scenario preserving the changes made in virtual machines with:
sudo vnx -f simple_ubuntu-gui.xml -v --shutdown
Stop the scenario discarding the changes with:
sudo vnx -f simple_ubuntu-gui.xml -v --destroy
See a graphical map of the virtual scenario using the --show-map option:
sudo vnx -f simple_ubuntu-gui.xml -v --show-map
tutorial_ubuntu.xml scenario
An scenario made of 6 Ubuntu virtual machines (4 hosts -h1, h2, h3 and h4- and 2 routers -r1 and r2-) connected through three virtual networks. The host participates in the scenario having a network interface in Net3. All systems but h1 use an Ubuntu server root filesystem; h1 uses an Ubuntu Desktop to allow starting a web navigator.
Start the scenario with:
cd /usr/share/vnx/examples/ sudo vnx -f tutorial_ubuntu.xml -v --create
See a graphical map of the virtual scenario using:
sudo vnx -f tutorial_ubuntu.xml -v --show-map
You can start the web servers in h3 and h4 with:
sudo vnx -f tutorial_ubuntu.xml -v -x start-www -M h3,h4
Start a firefox navigator in h1 automatically using vnx:
sudo vnx -f tutorial_ubuntu.xml -v -x www-h3
Restart a virtual machines individually with:
sudo vnx -f tutorial_ubuntu.xml -v --shutdown -M h1 sudo vnx -f tutorial_ubuntu.xml -v --create -M h1
Stop the scenario preserving the changes with:
sudo vnx -f simple_ubuntu-gui.xml -v --shutdown
Or discarding changes with:
sudo vnx -f simple_ubuntu-gui.xml -v --destroy
