I have been wondering what to do about questions that are solely about Amazon EC2 or VMware's virtualization products that don't have anything to do with actually developing for them. Example - this question about EC2 virtual cores. I have flagged some of these posts to be moved to Server Fault before and they were moved. I just wanted to have a firm ruling before I go flagging more posts.
The FAQ says that "software tools commonly used by programmers" are allowed, but hardware virtualization has purposes beyond programming. I really doubt the question would be allowed if it were about a physical CPU core, so I believe a question about a virtual CPU core should be treated the same way.
