You've answered the question yourself:
serverfault community is just for professionals
That is it. If you don't ask questions useful to a professional systems administrator, this is not the place for your question.
The kind of questions you've asked so far are mostly the kind that a professional sysadmin is expected to be able to handle. You've asked why a particular option didn't work in openvirtswitch - reading the documentation would have told you that. You've asked open-ended discussion questions like "is A better than B or the other way around". You've asked basic ifconfig questions.
None of those are appropriate here. The help centerhelp center has a section on what is appropriate and what is not. Please read it.
Most of your questions would be at home in http://superuser.com and some in http://unix.stackexchange.com. In both cases, you should start by googling for the answers and maybe searching those two sites, before posting. And also reading the Help Center for both sites.
Good luck!
