[launch instance] create volume during launch instance fails

[Matthias Runge]

I tried to launch an instance and to create volume (from an image) to boot from:

to mention: unchecking "Create new volume" fixes this issue

[Matthias Runge (mrunge)]

but obviously doesn't create a volume.

[Gary W. Smith (gary-w-smith)]

The stack trace indicates an error in the novaclient. Can you successfully perform the same operation with the 'nova' command line?

[Matthias Runge (mrunge)]

Gary, this just works in old launch instance dialogue.

[Travis Tripp (travis-tripp)]

Hi Matthias,

I definitely created many volumes in testing, so might be a version mismatch of some sort in what is expected. Would you be able to capture the exact JSON being sent to Nova from the two different launch instances (original and ng)?

Thanks,
Travis

Don't need to specify image since it already specified in block_device_mapping_v2 by 'uuid'.

For what its worth, I believe this stopped working because I was told that in Liberty Nova started rejecting requests that contain extra data. So, that's why this used to work.
