I think Jeremy refers to the 2.6.18 kernel though. And IMHO it isn't
misleading as this is the only option for a dom0 kernel. Well, was
until very recently, now you can also run the latest pv_ops bits with
dom0 support. That is still very young code though and I wouldn't use
that (yet) for production systems. Works fine on my development box though.
The bits needed for pv_ops based dom0 support in arch/x86 is small
compared to what is already there for domU support.
cheers,
Gerd
