Open Stack

Hello all,

Our ironic job has been broken and it seems to be due to a lack of IPs. 
We allocate two IPs to our job, one for the dhcp server, and one for the 
target node. This had been working for as long as the job has existed 
but recently (since about early December 2018), we've been broken.

The job is able to clean the node during devstack, successfully deploy 
to the node during the tempest run, and is successfully validated via 
ssh. The node then moves to clean failed with a network error [1], and 
the job subsequently fails. Sometime between the validation and 
attempting to clean, the neutron port associated with the ironic port is 
deleted and a new port comes into existence. Where I'm having trouble is 
finding out what this port is. Based on it's MAC address It's a virtual 
port, and its MAC is not the same as the ironic port.

We could add an IP to the job to fix it, but I'd rather not do that 
needlessly.

Any insight or advice would be appreciated here!

Thanks,
Mike Turek <mjturek>
