This change allows compute hosts to quickly download and cache images on the local compute host directly from Ceph rather than slow dowloads from the Glance API. New '[glance]/enable_rbd_download' option is introduced to enable this behavior. This is slight change compared to the original idea described in the relevant blueprint where it was discussed to use (now obsolete) '[glance]/allowed_direct_url_schemes' option. Additionally, when an image signature verification is requested, it should be done also for the image fetched by the new download handler. This was completely missing so far. New '[glance]/rbd_{user,pool,ceph_conf,connect_timeout}' configurables are introduced to allow operators to configure access to the cluster hosting Glance without the need to use the existing '[libvirt]' specific configurables. nova.storage.rbd_utils.RBDDriver has also been modified to accept these but continues to default to the '[libvirt]' specific configurables for now.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
Developers
For information on how to contribute to Nova, please see the contents of the CONTRIBUTING.rst.
