OpenStack CPU Pinning NUMA flavor

[STEP 1] Flavor 생성
$ openstack flavor create --ram 4096  --disk 50 --vcpus 10 CPU_PIN_NUMA_Flavor

 

[STEP 2] Flavor Property 생성
$ openstack flavor set CPU_PIN_NUMA_Flavor \
 --property hw:cpu_policy=dedicated \
 --property hw:cpu_sockets=1 \
 --property hw:cpu_threads=1

 

[STEP 3] Flavor 확인

flavor create

[STEP 4] VM 생성

$ net_id=$(openstack network show management -c id -f value)

$ openstack server create --flavor CPU_PIN_NUMA_Flavor --image cirros --nic net-id=$net_id \

--availability-zone nova:compute1 --wait CPU_PIN_NUMA_TEST_VM

 

[STEP 5] NUMA CPU Pinning 확인

$ virsh numatune 34
numa_mode      : strict
numa_nodeset   : 1
