Here is an example with just one node: [stack@undercloud ~]$ openstack baremetal introspection bulk start Setting nodes for introspection to manageable... Starting introspection of node: 304e594a-5585-4c25-a754-01864d872346 Waiting for introspection to finish... Introspection for UUID 304e594a-5585-4c25-a754-01864d872346 finished with error: Preprocessing hook validate_interfaces: No suitable interfaces found in {u'eth1': {'ip': None, 'mac': u'10:60:4b:a9:b8:7c'}, u'eth0': {'ip': None, 'mac': u'10:60:4b:a9:b8:78'}} Setting manageable nodes to available... Introspection completed with errors: 304e594a-5585-4c25-a754-01864d872346: Preprocessing hook validate_interfaces: No suitable interfaces found in {u'eth1': {'ip': None, 'mac': u'10:60:4b:a9:b8:7c'}, u'eth0': {'ip': None, 'mac': u'10:60:4b:a9:b8:78'}} Physical configuration The physical configuration was working before in Liberty, but just in case, I'm describing here for your input. The undercloud (virtual) server connects with NIC 1 to the internet and NIC 2 to an non internet connected switch. The overcloud servers connect with NIC 1 to the same switch, and NIC 2 to the internet, or are unplugged. Console When looking at the console on the overcloud node, I can see that the machine obtains a valid DHCP on NIC 1 and sends a DHCPDISCOVER on NIC 2 that, gets nowhere. A warning message appears as: ironic-python-agent[895]: date 895 WARNING ironic_python_agent.ironic_api_client [-] POST failed: HTTPConnectionPool(host='127.0.0.1', port=6385): Max retries exceeded with url: /v1/drivers/agent_ipmitool/vendor_passthru/lookup (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x2617f10>: Failed to establish a new connection: [Errno 111] Connection refused',)) If I try to run the command again, the server will not PXE boot again.
