Is it possible to save a compute instance from my devstack cloud to hard drive so that I can then upload it to a production cloud?

Googling made it seem easy - all I had to do was save an image of the instance from devstack, and then download it to my local machine after which I'd be able to upload it to a production cloud and get it running. Whenever I tried doing this though, I always got a 0 byte file.

I also tried creating an image from the volume attached to the instance, and this time I was able to download a file as big as my volume, but when I tried uploading it to the production cloud and using it to bring up a compute instance, it failed.

Are there any other ways to get this done?

Creating snapshots from volume based images result in 0 byte glance images, that's expected. The second approach would have been my recommendation, what is your storage backend for cinder? How did the second approach fail?
