Ah, the plot thickens.

Partition creation happens here:
http://git.openstack.org/cgit/openstack/diskimage-builder/tree/elements/vm/block-device.d/10-partition#n22

It might be worth dropping a bash right afterward to see whether that is
actually succeeding. Its possible that parted is failing but we aren't
catching that failure for some reason, or when we dd the image back on
to the block device we are failing horribly and writing over the
partition table (that would be a totally new bug to me though).

Alternatively, if you could paste a complete log of you image build
somewhere so we can dig through maybe we can spot something interesting.

Cheers,
