I was wondering about multiple OS instances in their own address space. What's the need for separate address spaces for the kernels ?
It looks more natural to me to _actually_ have N instances of kernel data structures in the _same address space_, i.e. turning each global variable into an array_ indexed by an "instance id", much in the same way as we have now per-CPU structures. Well, I don't actually think it would be as simple as stated above, I'm just proposing it as a general approach towards ccclustering.
(btw, there was some discussion on #kernelnewbies, on Nov 12th and 21st, you can find the logs here http://vengeance.et.tudelft.nl/~smoke/log/kernelnewbies/2001-11/)
