Research -> do participate.....
This is simple research on the present situation of having windows OS on top of XEN.
I have got to know that RedHat or SuSE etc doesnt support Windows as a guest OS even if its fully virtualized.
But documentation over the net says that there are many people who have successfully installed Windows OS on top of XEN, having LINUX as a host OS(i am not sure about which linux version).
So if you have got any information, even if you have not implement it, do comment and those who have successfully installed it then do share it like on which Host system it worked and all .
But as far as i know after lot of research that in coming year by end of march RedHat, SuSE would support windows as a guest OS.
