mac address XXX is not in the set of hypervisor macs

[Derek Higgins]

Tripleo CI tests started failing some time after 0130UTC this morning with

2015-09-11 08:36:30.028 | Stack failed with status: Resource CREATE failed: resources.Compute: ResourceInError: resources[0].resources.NovaCompute: Went to status ERROR due to "Message: No valid host was found. There are not enough hosts available., Code: 500"

Digging further we see this in the nova-compute logs (on the undercloud)

based on the timing of its merge and the fact that it deals with neutron ports, I tried out a revert of this heat commit

Given the Heat fix landed I think we can mark this close right?
