Detailed bug description:
With enabled cpu pinning for vm migration doesn't work properly
Steps to reproduce:
1) Deploy env with 2 compute node with enable pinning
2) Create aggregate states for this compute-node
3) Create 3 flavors:
- flavor with 2 cpu and 2 numa node
nova flavor-create m1.small.performance-2 auto 2048 20 2
nova flavor-key m1.small.performance-2 set hw:cpu_policy=dedicated
nova flavor-key m1.small.performance-2 set aggregate_instance_extra_specs:pinned=true
nova flavor-key m1.small.performance-2 set hw:numa_nodes=2
nova boot --image TestVM --nic net-id=93e25766-2a22-486c-af82-c62054260c26 --flavor m1.small.performance-2 test2
- flavor with 2 cpu and 1 numa node
nova flavor-create m1.small.performance-1 auto 2048 20 2
nova flavor-key m1.small.performance-1 set hw:cpu_policy=dedicated
nova flavor-key m1.small.performance-1 set aggregate_instance_extra_specs:pinned=true
nova flavor-key m1.small.performance-1 set hw:numa_nodes=1
nova boot --image TestVM --nic net-id=93e25766-2a22-486c-af82-c62054260c26 --flavor m1.small.performance-1 test3
- flavor with 1 cpu and 1 numa node
nova flavor-create m1.small.performance auto 512 1 1
nova flavor-key m1.small.performance set hw:cpu_policy=dedicated
nova flavor-key m1.small.performance set aggregate_instance_extra_specs:pinned=true
nova flavor-key m1.small.performance set hw:numa_nodes=1
4) boot vm1, vm2 and vm3 with this flavors
5) Migrate vm1: nova migrate vm1
Confirm resizing: nova resize-confirm vm1
Expected results:
vm1 migrate to another node
Actual resilts:
vm1 in ERROR
{"message": "Cannot pin/unpin cpus [17] from the following pinned set [3]", "code": 400, "created": "2016-03-31T09:26:00Z"} |
6) Migrate vm2: nova migrate vm2
Confirm resizing: nova resize-confirm vm2
Repeat one more time migration and confirmin
Expected results:
vm1 migrate to another node
Actual resilts:
vm1 in ERROR
6) nova migrate vm3 for 3 time
the same
Description of the environment:
iso #129 9.0, neutron+ubunt, 1 controller and 2 compute node with cpu pinning |
