Xen users - Nov 2009 - Is NUMA working correctly?

Hi Everyone,

I''m trying to bind CPU and memory usage to particular cores using some
Quad CPU 16 Core Opterons. They have 64GB RAM, 16 GB per node. It seems
that xm info shows it is not working as expected though, below are
details for the first node:

                         node3:10577


Any ideas? Is xm info wrong ( I thought it should show 0 in this
config)? Or is something wrong with the config?


Thanks,

Rob
