THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Here are some global configuration parameters needs to be documented.
We should able to figure out following in the Detailed Description part.
- What is the meaning/purpose of the parameter from an operational viewpoint?
- What is the example use case of the parameter? What kind of side effect can we expect by adjusting the value?
- What is the related component (such as virtual router, Dom0, guest VM) and correspondent configuration?
