Bug Description
The DHCP requests were not being responded to after they were seen on the undercloud network interface. The neutron services were restarted in an attempt to ensure they had the newest configuration and knew they were supposed to respond to the requests.
Rather than using the heat stack create (called in devtest_
nova boot --flavor $(nova flavor-list | grep "|[[:space:

bm-test1
Whilst the baremetal node was attempting to pxe boot a restart of the neutron services was performed. This allowed the baremetal node to boot.
It has been observed that a neutron restart was needed for each subsequent reboot of the baremetal nodes to succeed.

This suggests that neutron events to the agent were not propogating properly - almost certainly a neutron bug. Can you reproduce this?
