VNX Tutorial Ubuntu
(Work in progress....)
Contents
Description
VNX includes several example scenarios based on the VNUML tutorial scenario but including all types of virtual machines supported by VNX (see tutorial_*.xml files in /usr/share/vnx/examples directory).
The scenario presented here is made of 4 Ubuntu virtual machines (h1, h2, h3 and h4) and 2 dynamips virtual routers (r1 and r2) connected through three virtual networks. The host participates in the scenario having a network interface in Net3. All hosts use an Ubuntu server root filesystem.
Starting the scenario
Start the scenario with:
cd /usr/share/vnx/examples/ sudo vnx -f tutorial_ubuntu-dynamips.xml -v --create
You will see the six virtual machine textual consoles opening.
If you close a host or router console, you can reopen it with:
sudo vnx -f tutorial_ubuntu-dynamips.xml -v --console con1 -M <vmname>
being <vmname> the name of the virtual machine.
You can also open the consoles manually with the commands shown at the end of vnx execution:
---------------------------------------------------------------------------------- Scenario "tutorial-r1_all" started VM_NAME | TYPE | CONSOLE ACCESS COMMAND ----------------------------------------------------------------------------------------- h1 | libvirt-kvm-linux | con0: 'virt-viewer -c qemu:///system h1' or 'vncviewer :0' | | con1: 'virsh -c qemu:///system console h1' or 'screen /dev/pts/4' ----------------------------------------------------------------------------------------- h2 | libvirt-kvm-linux | con0: 'virt-viewer -c qemu:///system h2' or 'vncviewer :1' | | con1: 'virsh -c qemu:///system console h2' or 'screen /dev/pts/6' ----------------------------------------------------------------------------------------- r1 | dynamips-3600 | con1: 'telnet localhost 12000' ----------------------------------------------------------------------------------------- r2 | dynamips-3600 | con1: 'telnet localhost 12002' ----------------------------------------------------------------------------------------- h3 | libvirt-kvm-linux | con0: 'virt-viewer -c qemu:///system h3' or 'vncviewer :2' | | con1: 'virsh -c qemu:///system console h3' or 'screen /dev/pts/10' ----------------------------------------------------------------------------------------- h4 | libvirt-kvm-linux | con0: 'virt-viewer -c qemu:///system h4' or 'vncviewer :3' | | con1: 'virsh -c qemu:///system console h4' or 'screen /dev/pts/12' -----------------------------------------------------------------------------------------
You can show the previous table at any time with:
sudo vnx -f tutorial_ubuntu-dynamips.xml -v --console-info
See VNX Console Management for more details.
Executing commands
Stopping the scenario
To stop the scenario preserving the changes made inside virtual machines (it only works for ubuntu VMs, not for dynamips) you have to use the "-d" or "--shutdown" option:
sudo vnx -f tutorial_ubuntu-dynamips.xml -v --shutdown
You can later restart the scenario with:
sudo vnx -f tutorial_ubuntu-dynamips.xml -v --create
To stop the scenario discarding all the changes made in the virtual machine use the "-P" or "--destroy" option:
sudo vnx -f tutorial_ubuntu-dynamips.xml -v --destroy
Other interesting options
You can restart the virtual machines individually with:
sudo vnx -f tutorial_ubuntu-dynamips.xml -v --shutdown -M h1 sudo vnx -f tutorial_ubuntu-dynamips.xml -v --create -M h1
You can suspend and restore a virtual machine with:
sudo vnx -f tutorial_ubuntu-gui.xml -v --suspend -M h1 sudo vnx -f tutorial_ubuntu-gui.xml -v --resume -M h1
You can see a graphical map of the virtual scenario using the --show-map option:
sudo vnx -f tutorial_ubuntu-dynamips.xml -v --show-map
