Hi Michael,

FWIW, hyperv team and us are using the term "dom0" more and more to
avoid confusion between windows root and linux root, as dom0 is
always linux root. I did a quick search, and "dom0" is neither
copyrighted nor trademarked by xen, and I'm sure the fine folks
there won't be offended. Hopefully, [Hyper-V] tag would reduce
the confusion.

Just my $0.1

Thanks,
