[PATCH 0/6] Support for per-guest-node binding

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently we are only able to bind the whole domain to some host nodes
using the /domain/numatune/memory element.  Numerous requests were
made to support host<->guest numa node bindings, so this series tries
to pinch an idea on how to do that using /domain/numatune/memnode
elements.

That is incompatible with automatic numa placement (numad) since that
makes no sense.  Also this disables any live changes to numa
parameters (the /domain/numatune/memory settings) since we cannot
change the settings given to qemu.

Martin Kletzander (6):
  conf, schema: add 'id' field for cells
  conf, schema: add support for numatune memnode element
  conf: add virDomainGetMemsForGuestCpu()
  qemu: purely a code movement
  qemu: memory-ram capability probing
  qemu: pass numa node binding preferences to qemu
