AFAIUI setting dhcp_provider=none should be enough. Now, I don't know what DHCP confirmation you're saying - assuming you're using a pxe_* driver - the deployment of the node happens in 2 phases: 1) Ironic create the PXE configurations for that node, set the boot device, configure the DHCP server (in you're case it's non-op) and power on the node. 2) The node will boot the deploy ramdisk, expose the local disk as an iSCSI device and send it to Ironic[1] (is that the confirmation you're talking about ?). From there Ironic will write the image onto de disk, notify the ramdisk that the deployment is completed[2] and we are done. So we don't expect any confirmation from a DHCP server, can you please paste the error message you are getting?
