Discussion On OpenVZ For ORBIT Virtualization

One of the preliminary goals of running OpenVZ on ORBIT is to allow sharing a node's resources among multiple users. OpenVZ is a container based virtualization scheme for linux which works comfortably with the ORBIT boxes running a default debain distribution.

Outline

This page should provide you with basic information needed to go about getting OpenVZ running on the ORBIT boxes.

1. Load the precompied OpenVZ image named "openvz_orbit.ndz" using the omf load command as shown in the

baseline tutorials.

2. After the nodes are imaged. Turn the nodes on by using the omf

tell command.

3. Check the number of virtual private servers currently running.

Consult the users guide located here ​http://download.openvz.org/doc/OpenVZ-Users-Guide.pdf for more details.

4. Create devices, assign proper IP addreses to physical / virtual devices running on the

node by using the madwifi driver commands.

5. IP addresses for containers can be updated to ensure proper physical devices

forward and receive packets from the desired physical interface.

6. Eventually, with proper setup, the user can try and run ping/iperf from a container running on

one machine to a container running on another machine.
