Tight. At least code freeze is a bit later! :-P > Last updated: 8 August 2013 > > =3D=3D Backlog =3D=3D >=20 > =3D=3D=3D Testing coverage =3D=3D=3D >=20 > [..] > * Performance benchmarking on top of osstest @dario > =3D=3D=3D Big ticket items =3D=3D=3D >=20 > * NUMA Memory migration > owner: dario@citrix > status: in progress >=20 Confirmed to be in progress. > * Meta: PVIO NUMA improvements > - NUMA affinity for vcpus > owner: Dario > status: in progress > - PV guest NUMA interface > owner: Elena > status: in progress Right Elena? > - Sensible dom0 NUMA layout > status: not started > - Toolstack pinning backend thread / virq to appropraite d0 vcpu > status: not started Also, we might want to add: - HVM guest NUMA owner: Matt Wilson status: ? Is that ok, Matt? If you're concerned about the libxl part of that, I have a series half backed that I'll be posting here soon (as RFC or something), so feel free to leave that to me. :-) And this one too: - NUMA-aware ballooning owner: Li Yechen status: ?

This is an old discussion which, if I remember correctly (at least what the "NUMA angle" was), is about a TOCTOU issue involving automatic NUMA placement and ballooning, domain creation, and perhaps even more memory related operations (depends on the toolstack)... It's not "just" a ballooning or autoballooning problem, and it's completely different from the "NUMA-aware ballooning" I was talking about before. I don't have much in mind to properly deal with it. One think I can double check is whether the claim mechanism Oracle introduced can be of any help, but nothing much than that for now. In any case, at least from my side, this is as follows. status: not started.
