Hello, After doing some research, I''ve decided to go ahead and start a port of ReactOS to Xen. For those in the Xen community not familiar with ReactOS: it''s an open-source (GPL) re-implementation of the Microsoft Windows NT-based line of operating systems, aiming to provide binary compatibility for both applications and drivers (http://www.reactos.com). For those in the ReactOS community not familiar with Xen: it''s an open-source (GPL) virtual machine monitor that supports execution of multiple guest operating systems with unprecedented levels of performance and resource isolation (http://www.cl.cam.ac.uk/Research/SRG/netos/xen/index.html). Initially I''ll focus on getting ReactOS running as a guest OS. This should benefit ReactOS primarily, since this will make it possible to develop large parts of ReactOS (everything except for hardware drivers and some low-level memory management) inside Xen. It will also give ReactOS access to some hardware not natively supported yet (by using the Linux driver). The benefit for Xen at this stage would be the development of ReactOS device drivers for interfacing with Xen, which could also be used for a Windows XP port. On the longer term, I see no reason why ReactOS couldn''t function as a driver domain. As driver compatibility improves in ReactOS, this could provide Xen guests access to hardware for which the manufacturer provides only Windows drivers (due to Xens nature, not every driver could be used this way, but I bet a large percentage of the drivers depend on the kernel to do the really low-level stuff). All in all, it seems a win-win proposition for both projects. And even more importantly, I think it''s a cool project :-) I''ve made a branch in ReactOS svn, svn://svn.reactos.com/branches/xen, for this port. Of course, the goal is to merge the changes into trunk eventually. I expect the port to take at least a few months, my initial feeling is that it should be done by the end of the year (there''s lots of other stuff in ReactOS I want to work on too). The wiki page at http://wiki.reactos.com/Xen_port will be used to keep track of progress. The game plan is just start working from the boot code, until a problem is hit. Fix that problem and continue until the next problem. Any support and help from the Xen and ReactOS communities are of course greatly appreciated.
