I remember having seen that discussion but not the details. I'll check when back from vacation. > I think part of enablement of ' numa =3D 1' is to wrap it with >=20 > if (xen_initial_domain() && xen_supports_this_hypercall()) > numa =3D 1; >=20 > in the #2 patch. >=20 Mmm... Did you mean '!xen_initial_domain()' ? Or is it me that did not understand your comment about Dom0 above? In case you did mean '!', again, this would be fine for now, since the target is DomUs. At the point when we will start chasing Dom0, it would be interesting to find a solution to this issue... :-/ Anyway, thanks for pointing this out.
