I wanted to chime back in with the solution to the issue I was experiencing.
The source of the issue undoubtedly was me. I was trying to launch a flavor which had insufficient root-disk for a xenial.img (2G). The the traceback which indicated the insufficient disk error was being obfuscated by the user facing error I was seeing, block_device_mapping error [0]. This alongside the erroneous log error messages from service startup led me down unwarranted rabbit holes. I thought I was deploying the most stripped down instance with the bare essentials from the horizon ui, in reality (thanks beisner) you can deploy an even more stripped down instance (without a block device) from the command line with the command `openstack server create foo --flavor <flavor-name> --image <image-name>`. Deploying an instance without a block device allowed us to bypass the block_device_mapping error and get the real underlying traceback [1]. Massive thanks to Beisner for taking the time to talk through that with me, and pointing out the command^ that led us to the real error. ~James [0] https://paste.ubuntu.com/p/pTPh5vhBPp/ [1] https://paste.ubuntu.com/p/3XtxTTFXHM/ On Thu, Feb 15, 2018 at 7:49 AM, James Beedy <jamesbe...@gmail.com> wrote: > Junaid and James, > > > Thanks for the response.
