Setting Image (Create new volume) as the default instance boot source

Afternoon Ask Openstack,

The question in the title pretty much says it all but I will expand on why. In my work place we use TestKitchen to run tests for our software and cookbooks, these tests are running by our CI system with the --parallel tag mean all the tests run side by side.

When all the tests (10 all together) are spun up side by side it causes the disk on the computer node (which we only have one of right now) to hit 100% usage because of this some of downloads inside the test timeout and hang. Our [hopeful] solution is to hand of the disk IO to our SAN that is attached as a volume store.

The problem we are having is that I can't find any way to set the default boot source option to "Boot from image (creates new volume)", is there anyway to do this?

Same command may be performed via CLI and just placed inside script which will make this option default

This isn't really what I am looking for, I can change the command used by TestKitchen to make the instances, it is part of a Ruby API (fog). I was wondering if there is a settings in the nova conf that will allow me to set this
