PC server on Linux in VM? (virtual maction)

[Linux user Awesome]

I hope this is the right place to post this

I want to make a SWBF1 gameserver on Linux in a VM.
for SWBF1 PC players.
could anyone please tell me what the specs of the VM
should be?

I would prefer it to be Linux running in the VM.
but if I have to I might be able to find a win2000 iso
for it.
I'm using virtualbox by the way

and how to make it host mod maps aswell.
please step by step easy follow instrustions.

I hope someone can help.

thanks
