Open Stack

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

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.
