User Mode Linux

I've covered networking in sufficient detail earlier in the book that I don't need to belabor it here. However, I will repeat a few important points.

• Given that you control the host, the only two networking mechanisms you should consider for allowing access to the host network are TUN/TAP and uml_switch.

• Both bridging TUN/TAP devices with the host Ethernet and routing to unbridged TUN/TAP devices are appropriate models. They have differing setup and security requirements, which should drive the decision between the two.

• Make use of the ability to give descriptive names to your TUN/ TAP devices to document your UML configuration.
