I need a unixy environment for development purposes. I hate doing things on windows but it is more stable for daily use and I don't have a mac, so I'm having to use windows (7).

I want to run freebsd in a virtual machine, configure it to be the localhost server, be able to connect using ssh (within my home-network) and be able to install vbox guest addons.

If guest additions aren't the best, I can use solaris or linux flavours. I need no gui. I don't know anything about network stuff, so I need a detailed explanation from vise people here, or a nice doc to read.

Edit : To be more specific as requested, I use following on unices: *django 1.4
*apache
*python (2.7)
*emacs
*mysql
*probably node.js
*bash scripting

I use windows to be able to do daily things easily, like connecting to my tablet, browsing and learning java. And I don't want to use linux as my desktop os, beacuse it gets broken a lot, it's annoying to maintain wlan problems and some more.
