Public bug reported:
Hi All,
I am using openstack kilo with ceph backend. Creating a snapshot of an
instance works fine, but launching an instance from the snapshot fails.

-----------------------------------------------
I have found similar bugs: https://bugs.launchpad.net/python-
glanceclient/+bug/1447193, but I am able to list images with glance
after snapshot.
This is due to the presence of ramdisk_id and kernel_id fields in
image_properties table of glance database. When I delete these 2 fields,
then I am able to boot instances from the snapshot successfully. I have
attached the glance and nova config files.

-----------------------------------------------
I have found similar bugs: https://bugs.launchpad.net/python-
glanceclient/+bug/1447193, but I am able to list images with glance
after snapshot.
This is due to the presence of ramdisk_id and kernel_id fields in
image_properties table of glance database. When I delete these 2
fields, then I am able to boot instances from the snapshot
successfully. I have attached the glance and nova config files.
