Re: [Xen-devel] Patch question (Hyper-Threading support)

        Hi all,

        Well, based on some quick inspections on the that I checked out from
the mercurial repository this afternoon, it seems that the HT support
has been already implemented. :-)

        Thus, here is a suggestion, it would be nice to make more details
available about who is doing what and in which phase of development
things are, this information could avoid duplicated efforts.

        Thanks,
        Eli
