Err.. you realise the overhead of virtualisation is probably a bit taxing for the poor old N900 with 256MB of RAM and "only" a 600Mhz processor? (...) The only levels of virtualisation that exists on N900 at the moment properly are the side-by-side stuff that doesnt run as an abstraction space like Easy Debian and Preenv. They both use the same underlying architecture and shared with a guest OS - more like an additional set of libraries on top of Maemo. Until Nokia releases something better (Dual core, 1GB+ RAM) then theres very little to no hope of using virtualisation as such - hence why VMWare even dropped their mobile virtualisation project for Maemo.
