Comment 4 for bug 1609193

Thank you.

The resize action of this instance failed because scheduler core_filter return 0 hosts. So I think this is a scheduler problem.

One host's free vpus is 3, a instance with 1 vcpus on this host. when this instance want to be resized to 4 vpus, I think this resize action should be successful, because host_free_vcpus + instance_current_used_vcpus == resized_instance_required_vcpus.(3 + 1 == 4)
