This indicates that you might be using the wrong PXE boot template in your ironic.conf file.

grep ^pxe_config_template ironic.conf

$ grep ^pxe_config_template ironic.conf
pxe_config_template=$pybasedir/drivers/modules/ipxe_config.template

The default template is pxe_config.template, so it is easy to miss the i to turn this into ipxe_config.template.

When you try to log in at the login prompt on the console of the node with the root password that you set in the configurations steps, but are not able to, it indicates you are not booted in to the deployed image. You are probably stuck in the deploy-kernel/deploy-ramdisk image and the system has yet to get the correct image.

To fix this issue, verify the PXE Boot Configuration file in the /httpboot/pxelinux.cfg/MAC_ADDRESS on the Compute or Bare Metal service node and ensure that all the IP addresses listed in this file correspond to IP addresses on the Bare Metal network.

For example, the kernel line in your file is as follows:

kernel http://192.168.200.2:8088/5a6cdbe3-2c90-4a90-b3c6-85b449b30512/deploy_kernel selinux=0 disk=cciss/c0d0,sda,hda,vda iscsi_target_iqn=iqn.2008-10.org.openstack:5a6cdbe3-2c90-4a90-b3c6-85b449b30512 deployment_id=5a6cdbe3-2c90-4a90-b3c6-85b449b30512 deployment_key=VWDYDVVEFCQJNOSTO9R67HKUXUGP77CK ironic_api_url=http://192.168.200.2:6385 troubleshoot=0 text nofb nomodeset vga=normal boot_option=netboot ip=${ip}:${next-server}:${gateway}:${netmask} BOOTIF=${mac}  ipa-api-url=http://192.168.200.2:6385 ipa-driver-name=pxe_ipmitool boot_mode=bios initrd=deploy_ramdisk coreos.configdrive=0 || goto deploy

If a value does not correspond between the /httpboot/pxelinux.cfg/MAC_ADDRESS and the ironic.conf file:

With certain hardware, you might experience a problem with deployed nodes where the nodes cannot boot from disk during successive boot operations as part of a deployment. This usually happens because the BMC does not honor the persistent boot settings that director requests on the nodes. Instead, the nodes boot from a PXE target.

In this case, you must update the boot order in the BIOS of the nodes. Set the HDD to be the first boot device, and then PXE as a later option, so that the nodes boot from disk by default, but can boot from the network during introspection or deployment as necessary.

If the Bare Metal service is not getting the right hostname, it means that cloud-init is failing. To fix this, connect the Bare Metal subnet to a router in the OpenStack Networking service. The requests to the meta-data agent should now be routed correctly.

If you are having trouble authenticating to the Identity service, check the identity_uri parameter in the ironic.conf file and make sure you remove the /v2.0 from the keystone AdminURL. For example, identity_uri should be set to http://IP:PORT.

Issues with enrolled hardware can be caused by incorrect node registration details. Ensure that property names and values have been entered correctly. Incorrect or mistyped property names will be successfully added to the node’s details, but will be ignored.

Update a node’s details. This example updates the amount of memory the node is registered to use to 2 GB:

openstack baremetal node set --property memory_mb=2048 NODE_UUID

$ openstack baremetal node set --property memory_mb=2048 NODE_UUID

If the Compute scheduler cannot find a suitable Bare Metal node on which to boot an instance, a NoValidHost error can be seen in /var/log/nova/nova-conductor.log or immediately upon launch failure in the dashboard. This is usually caused by a mismatch between the resources Compute expects and the resources the Bare Metal node provides.
