> There is no need for a second img to use as swap right? Yes and no. On physical machines I am very used to putting swaps on separate controllers and drives for performance reasons as am sure many others here are. I have yet to see that pay off on Xen, but I really haven't had a "hammered on" system in production yet. All are smaller and much, much more focused on precisely what they need to do and not commingled as multipurpose machines (e.g. webserver + file server + vpn server). It is an engineering and use question and YMMV, but you can always add it later if the need arises and by really measuring where you are bottlenecking.
