Hi Daniel,
Do you think I should go ahead and implement this ? Any comments or concerns ?
Hi,
Here is another attempt at guest NUMA topology XML specification that
should work for different NUMA topologies.
We already specify the number of sockets, cores and threads a system
has by using:
cpu
topology sockets='2' cores='2' threads='2'
/cpu
For NUMA, we can add the following:
numa

I see that there is no way to specify such NUMA topology in libvirt

Libvirt already supported NUMA setting (both cpu and memory)

Hence I am not sure if if numatune is the right place for defining
host NUMA topology which btw should be independent of the host

Sorry for the typo.

Maybe something like:
numatune
guest
..
/guest
/numatune
Yes, one possible solution.
Let me wait and see what others say and what will be the consensus.
