Before I get to look at this latest version, may I go a step back and
ask for clarification whether all of these (seemingly fragile)
manipulations are actually needed (such a rationale for the series
would btw be quite good to have in the overview mail, rather than
having to wade through mailing list history). In particular, why is it
that we need a new domain in the first place? After all, native
kexec doesn't imply a new physical machine either. Perhaps that
was discussed a long while back, but I can't seem to find any of
that now that I would like to read through it again.
