Just retaking the discussion of some days ago. After some discussions here
and considering the suggestions in this thread, we got 3 main ideas for the

+ make thinks clea

Hi all,
We are planning to implement DLPAR capacity on QEMU pSeries. As we

to give us some design directions
and confirm if we going in the right direction. Our first idea is:
1 - to patch 'spapr.c' so it can dynamically i
