utilize gluster as a backend for glance w/ direct access to glusterfs from Nova (no http get needed)
The solution to this will be broken down into steps. A more advanced solution will be worked on in parallel with a initial and incremental solution. For the initial solution we will achieve this functionality by requesting the direct_url location information from glance. If that information is available, and is pointing to a file url nova compute will perform a file copy. For the first patch we will make the assumption that the glance and nova compute share a file system that has the same name space. In incremental patches to come shortly after we will add functionality to glance such that it describes the name space of its file system and its mount point. Similar information must be added to nova compute so that a copy is only made if the name spaces match, and that the path can be adjusted for nodes that use different mount points.
An upstream patch has been posted here: https://review.openstack.org/#/c/37817/. If accepted it will complete this work.
An upstream patch has been approved here: https://review.openstack.org/#/c/37817/ This completes the code changes needed for this bug. Documentation will be needed as well.
This depends on updates to warlock and jsonschema (and new python-json* deps[2]) Related upstream bugs: https://bugs.launchpad.net/nova/+bug/1208656 https://bugs.launchpad.net/glance/+bug/1202391 [2] new python-json* Fedora Reviews: https://bugzilla.redhat.com/show_bug.cgi?id=982351 https://bugzilla.redhat.com/show_bug.cgi?id=982352
I got that wrong, jsonschema 1.3.0 should be enough, but 2.0.0 is also fine: https://github.com/openstack/requirements/commit/005fd50c2d4dc17be8204bbd15895e11445e43af
