[[6.6.0-rc2] VM Memory allocation across numa boundaries]

Wow, I never even considered how the memory channels could play into all of this. Thanks so much for the detailed response. 👍

I've sorted it for now by flushing the disk cache before launching the VM. Then it get's it all from the second node.

[[6.6.0-rc2] VM Memory allocation across numa boundaries]

I was just looking for this info, I noticed so bad RAM performance on my dual xeon server. Running numactl --hardware and shutting the machine down showed all the ram was allocated from numa node 0 when all my cpu cores were pinned to numa node 1. I added...
 

<numatune>
    <memory mode='strict' nodeset='1'/>
  </numatune>

and it almost worked, it took all the RAM from node 1 down to 2.5GB and then pinched the remaining 6GB from node 0, suppose that's better then not starting at all. Since my main vm uses the entire 2 CPU, [I have isolated that cpu from unraid]. Can I persuade unRAID to keep away from that ram? It seems to use it up pretty fast from boot.
