Comment 2 for bug 1188543

Simon, can you provide some more descriptive detail on how you triggered it?

  - For instance, what's the nova CLI you used?

 Is it something like:

   $ nova boot --flavor 1 --image e1b71961-d66d-4315-8e83-32aa1bd44f3f \
   --block_device_mapping vda=2c370395-7f59-4c89-b312-ba35dbb986c0:::0 \
   --key_name oskey f17_volume_backed

Or something else?

It'll also be help triage things quicker, if you can provide as much verbose details as possible.
