[VMware]: migrate/resize failed in same host with vmware driver

[lee jian]

Same to bug 1161226, this issue exist for vmware driver , when resizing a vmware instance with option "allow_resize_to_same_host = True" in nova.conf, the resize operation failed due to report using duplicated mac address . Cold migrate also failed .This only occurred resize/migrate in same host, not between two hosts .

Marked as confirmed as this has been tagged, prioritized, and assigned.

`allow_resize_to_same_host` seems to have no effect in M release. Despite having it set to true it still ignores the source host when determining where to migrate it to for resizing.

I am not able to reproduce this problem running latest Nova and Neutron with DVS plugin. I think this was a problem when using nova-network which is no longer supported, so I will resolve the bug as "Invalid". Feel free to reopen if you manage to reproduce.
