I want to run windows 8 as a guest os with virtualbox on some thinkpad (haven't bought one yet) running Ubuntu 12.04. Apart from virtualizing windows 8 (mostly just for use with the office suite app) my needs are very modest, I don't need much more than emacs and a browser. What I'd like to know is what kind of specs will be necessary to run windows 8 well as a vm, using the office apps. It would be a shame to waste money on overpowered hardware.
Are there any official guidelines from oracle or windows on this? Would this lenovo x220, for example, be sufficiently strong? (Edit: I plan to add 4gb more ram for the maximum 8gb)The specs below were taken from this review.
