Hi,
I have a host machine which contains 4 numa nodes each with 2 GB memory and 4 cpus. I am
using qem-kvm hypervisor.
I am trying to create a guest with the similar topology (4 numa nodes, with only 2 vcpus
and 1 GB memory) as host. Each vcpu is 1-1 pinned to physical cpus(i.e. guest{socket0
cpu0} is pinned to host{socket0 cpu0). But one critical requirement is that one guest
socket should not have memory from two host sockets to avoid numa access completely.
With the current constructs of numa/topology I am able to create the guest. But memory is
not mapped as socket 1-1. numatune is not helping. Please suggest a possible way.
Thanks,
Kapil
