Emulab FAQ: Software Setup: How do I select which OS to run on each node?

When a choice of OS is available, you may specify which one you prefer for each node in the NS file using the Emulab tb-set-node-os extension to NS. When your experiment is configured, the appropriate disk image will be loaded on your nodes, and the selected operating system will boot up on each.

Please see the Extensions page for a summary of all Emulab NS extensions, and the Emulab Tutorial for an example.
