It does, as far as Harmandeep told me.

Also, that same Linux kernel binary boots as baremetal.

ISTR (but, Harmandeep, correct me if I'm wrong) that it was booting
fine as Dom0, if the Ubuntu packaged version of Xen was used (which I
think is 4.5).

Yeah, but again, it was booting as dom0 with another Xen... doesn't
that mean that Xen at least has a role in exposing it?

Also, what would you think it's better to try next... try another
kernel?

Thanks and Regards,
