Comment 7 for bug 1671379

Hello, Timofey Durakov, Sivasathurappan Radhakrishnan
I don't test the patch mentioned in comment #4 yet.
The libvirt version of the bug (https://bugs.launchpad.net/nova/+bug/1671379) environment is 1.2.17， it is less than the lowest version of the post-copy bug ( https://bugs.launchpad.net/neutron/+bug/1414559).

I'm sure that the bug I committed is concerned with ml2-hierarchical-port-binding.
