Hi Zhi,

The error says almost it all, you are using the agent_ssh driver and
it does not support deploying partition images (meaning that it will
not partition the disk for you). When using that driver you should use
a whole disk image (an image that contains the partitions and a
booloader installed on it).

If you want to use a partition image you can use the pxe_ssh driver,
it does supports both types of image.

Also, there's work being done in a project called ironic-lib[0] which
is re-factoring the code that the ironic-conductor use to partition
the disk so it can be shared with the IPA ramdisk (that will be used
by the agent_ssh driver to partition the disk in-band) as well.

Hope that helps,
