Open Stack

Hello,

I am using Ironic for deploying baremetal to my openstack environment.
Using Liberty version on Ubuntu 14.04. I followed Ironic documentation  to
deploy x86 servers using pxe_ipmitool. Now I have a working Ironic setup
for PXE boot. I also want to add my test board running ARM 64 bit CPU to
ironic deployment. I would like to try using fake_pxe drivers because my
board don't support IPMI or anything else for out of band communication. So
idea was to do deployment without power management, eventually fake_pxe is
the obvious choice. But I have problem in updating the Ironic node which I
will explain below.

I created ironic node using fake_pxe driver. Added all necessary parameters
using node-update command. Node-show command output is given below for
reference


ironic node-show orange-box

Because of this during nova boot, scheduler failed to boot the BM instance.

Can anyone help me with what's wrong in my configuration?....



Thanks in advance,
