Hi folks:

As a learning exercise[1], I tried to reproduce this bug.

Here are my notes from two test cases I tried using a multi-node devstack sandbox.

1. Source host vcpu_pin_set is larger than the destination host vcpu_pin_set:

2. Source host vcpu_pin_set is the same size as the destination host vcpu_pin_set, but with completely different values:

    http://paste.openstack.org/show/473286/

Conclusion: The live migration completed successfully in both cases, and it looks to me like the cpuset attribute was updated correctly to match the destination host policy, but perhaps I've misunderstood & failed to simulate a case that would trigger a migration failure or policy conflict.

Thoughts?
