Nova fails to boot signed image

[Darren]

Description
===========
Nova fails to boot an image which has been signed (using glance image-create) which uses a base64 image signature. By default base64 uses linewrapping after 76 characters. Disabling line wrapping with -w 0 should solve the issue by I'm sure there are alternatives.

Steps to reproduce
==================
Following these instructions to create a signed image:

https://github.com/openstack/glance/blob/master/doc/source/signature.rst

But using base64 without -w 0.

Booting the image that was created using 'nova boot' the image used will be the one just created and the flavor used is m1.tiny.

Expected result
===============
Booting the signed image should be successful.

Actual result
=============
Booting the signed image fails.

Environment
===========
This is using the mitaka branch.

Logs & Configs
==============
Here is the output:

ERROR (ClientException): Unexpected API Error. Please report this at http://bugs.launchpad.net/nova/ and attach the Nova API log if possible.
<type 'exceptions.AttributeError'> (HTTP 500) (Request-ID: req-337f86d3-697b-40a1-ac77-0cd5211ad4ad)

I tried uploading the Nova API log but it just gives a timeout error.

Is there anything output in the glance log that's specific to this failure? (The nova failure above is a generic 500 failure, so isn't specific enough to link to this issue).

Thanks.

    Image signature base64 don't wrap lines

    In the image signature documentation, base64 should not use line
    wrapping (defaults to 76). Disable using -w 0. With line wrapping
    enabled Nova will fail to boot the image.

    Added a note to inform users to use -w 0 with Glance v1 but is
    optional for v2.
