I want to start a server but all my application will be in a virtual partition. Therefore, I need just a very minimal core OS that can support virtualbox as there will no usage of core OS other than start up the virtualbox. Any OS that is suitable for this situation? Tried JEOS and Fedora minimal installation which is only CLI. However, I cant make those 2 OS to support virtualbox. Please help. Sorry Im totally new to Unix and CLI. Thanks
