[Rdo-list] Failing to deploy Mitaka on baremetal

Hi, I'm trying to deploy Mitaka on a baremetal environment composed by 3 controllers and 4 computes. After introspection nodes seems fine, even for one of them I need to do introspection by hand, since it was not completing the process. But in the end all my 7 nodes were in state "available". Launching the overcloud deploy, the controller part it goes fine, but then it gives me this error about compute: 2016-02-05 09:26:59 [NovaCompute]: CREATE_FAILED ResourceInError: resources.NovaCompute: Went to status ERROR due to "Message: Exceeded maximum number of retries. Exceeded max scheduling at tempts 3 for instance 0227f7c1-3c2b-4e10-93bf-e7d84a7aca71. Last exception: Port b8:ca:3a:66:ef:5a is still in use. The funny thing is that I can't find anywhere the incriminated ID it's not an Ironic node ID and neither a Nova one. Can you help me point the attention in the right direction?
