Hi All,
I am working on CPU Pinning feature of master branch of NOVA. Setup is
devstack.
I want to pin vcpus to pcpus using flavors and I have only one compute
node. No host aggregates
created.
I have created cpu pinning flavor and set cpuset and vcpupin parameters
using
1) nova flavor-create pinned.medium 6 2048 1 2
2) nova flavor-key 6 set "hw:cpu_policy"="dedicated"
3) nova flavor-key 6 set "hw:cpu_threads_policy"="prefer
4) nova flavor-key set 6 set vcpupin:0=1
5) nova flavor-key set 6 set vcpupin:1=1
srinivas@srinivas:~/devstack$ nova flavor-show 6

| Property | Value

+----------------------------+-------------------------------------------------------------------------------------------------------+
| OS-FLV-DISABLED:disabled | False
|
| OS-FLV-EXT-DATA:ephemeral | 0
|
| disk | 1
|
| extra_specs | {"hw:cpu_policy": "dedicated",
"vcpupin:0": "1", "hw:cpu_threads_policy": "prefer", "vcpupin:1": "1"}

| id | 6

| name | pinned.medium

| os-flavor-access:is_public | True
|
| ram | 2048
|
| rxtx_factor | 1.0
|
| swap |
|
| vcpus | 2
|
+----------------------------+-------------------------------------------------------------------------------------------------------+
Now If I try to launch guest vm, I could not able to see above set cpuset
and vcpupin parameters in guest.xml. vcpus are running on different cores
on its own.
Please suggest me, how can I set above parameters in guest xml and validate
CPU Pinning feature.
Thanks in advance,
Srinivas.
