Code review comment for lp:~citrix-openstack/nova/xenapi-glance-2

I am not entirely sure what Ewan really meant it with 'heavily reworked', but by following a discussion on the mailing list I understand that the extent of the work may be related to when glance-auth gets underway in Cactus.

As for the rest, we tried this branch internally against Glance revno 34 and everything seemed to work okay.

Hope this help!
