Fixed bugs:
- openstack2 IPv6 address.
- Allow libvirt to open Ceph client cinder keyring.
- Applied patch manually (https://git.openstack.org/cgit/openstack/cinder/diff/cinder/image/glance.py?id=1e488339ded20a8bce602202bde7244f1c1b249e) to notify missing attribute, instead of raise error, while creating volume from image using Ceph backend.
- Again Ceph: when instance is created directly from image, its root disk size is 1000x larger than provisioned (https://bugs.launchpad.net/nova/+bug/1332342). Removed “* units.Ki” in line 651 (https://git.openstack.org/cgit/openstack/nova/tree/nova/virt/libvirt/imagebackend.py#n651).
