Hi Peeyush,

Now, the problem is that external DHCP is not able to send confirmation

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

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?
