hi we are trying to deploy kolla based openstack (newton) with numa capabilities . After deployment virsh dumpxml <cputune> does not show the related cpu set instaed it just dhows

  <cputune>
    <shares>1024</shares>
  </cputune>

we have created a nova.conf inside /etc/kolla/config folder :

[DEFAULT]
vcpu_pin_set=1,20,3,5,15,11,17
[libvirt]
virt_type = qemu
cpu_mode = none

I dont think numa works with qemu and cpu_mode none

hi can you help us with the config to be used in nova.conf apart from default configuration for numa to work

I dont have any cpu supporting NUMA, but I would say that virt_type qemu is the wrong config since numa is a hardware feature and qemu dont even can use vmx. Just removing that two options will use default cpu virt_type(kvm). Apart from that, I cannot help since I dont have the proper environment
