The iPXE boot process uses HTTP to boot the introspection and deployment images. Older systems might support only a standard PXE boot, which boots over TFTP.
To change the boot process from iPXE to PXE, edit the undercloud.conf file on the director host and set ipxe_enabled to False:
ipxe_enabled = FalseSave this file and run the undercloud installation:
$ openstack undercloud installFor more information on this process, see the article "Changing from iPXE to PXE in Red Hat OpenStack Platform director".
