Robert, Do you have any more information about what the details of this virtualization work will be? e.g. will it be similar to what Solaris has with zones? The reason that I ask is that I've just finished getting the ipfilter code (non-Sun code) converted to being zone aware. What does that mean? Lots of global variables are gone, replaced by soft-context structures that are allocated and free'd when zones come alive/die. For BSD, while all of the code paths are the same, I'm currently only using a single soft context and just pass around a pointer to it. If you're going to be doing similar work for FreeBSD, I will try and get this into the tree sooner, rather than later, so that there's one less component that you need to worry about.
