Open Stack

Hi, All,

I am verifying numa aware vwitch features (https://specs.openstack.org/openstack/nova-specs/specs/rocky/approved/numa-aware-vswitches.html). But the result is not my expectation.

What I missing?


Nova configuration:

[filter_scheduler]
track_instance_changes = False
enabled_filters = RetryFilter,AvailabilityZoneFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter,SameHostFilter,DifferentHostFilter,NUMATopologyFilter

[neutron]
physnets = physnet0,physnet1

[neutron_physnet_physnet0]
numa_nodes = 0

[neutron_physnet_physnet1]
numa_nodes = 1


ml2 configuration:

[ml2_type_vlan]
network_vlan_ranges = physnet0,physnet1
[ovs]
vhostuser_socket_dir = /var/lib/libvirt/qemu
bridge_mappings = physnet0:br-physnet0,physnet1:br-physnet1


command list:

openstack network create net0 --external --provider-network-type=vlan --provider-physical-network=physnet0 --provider-segment=100
openstack network create net1 --external --provider-network-type=vlan --provider-physical-network=physnet1 --provider-segment=200
openstack subnet create --network=net0 --subnet-range=192.168.1.0/24 --allocation-pool start=192.168.1.200,end=192.168.1.250 --gateway 192.168.1.1 subnet0
openstack subnet create --network=net1 --subnet-range=192.168.2.0/24 --allocation-pool start=192.168.2.200,end=192.168.2.250 --gateway 192.168.2.1 subnet1
openstack server create --flavor 1 --image=cirros-0.3.5-x86_64-disk --nic net-id=net0 vm0
openstack server create --flavor 1 --image=cirros-0.3.5-x86_64-disk --nic net-id=net1 vm1

vm0 and vm1 are created but numa is not enabled:
  <vcpu placement='static'>1</vcpu>
  <cputune>
    <shares>1024</shares>
  </cputune>






Thanks,
