After installing the undercloud based on mitaka, the deploy of the overcloud in baremetal
servers is not working. When the servers are trying to PXE boot, they don’t get any
responses back. I’ve used tcpdump on several parts of the undercloud to see what was going
on when the baremetal servers were PXE booting and this is what I obtained:
-------------------

-------------------
I deployed the undercloud using the default network configuration (192.0.2.x) and I can
see that dnsmasq is running:
[stack@undercloud ~]$ ps aux | grep dnsmasq

Ideas?
