I figure out temorary fix by changing /usr/lib/python2.7/dist-packages/nova/virt/libvirt/storage/rbd_utils.py around line 193 form
if image_meta.disk_format != 'raw':
reason = ("rbd image clone requires image format to be "
"'raw' but image {0} is '{1}'").format(
url, image_meta.disk_format)
to:
if image_meta['disk_format'] != 'raw':
reason = ("rbd image clone requires image format to be "
"'raw' but image {0} is '{1}'").format(
url, image_meta['disk_format'])
This fix solved problem in my setup. RAW images use properly snapshot
and clone function of CEPH.
Best regards,
KK

I figure out temorary fix by changing /usr/lib/python2.7/dist-packages/nova/virt/libvirt/storage/rbd_utils.py around line 193 form
if image_meta.disk_format != 'raw':
reason = ("rbd image clone requires image format to be "
"'raw' but image {0} is '{1}'").format(
url, image_meta.disk_format)
to:
if image_meta['disk_format'] != 'raw':
reason = ("rbd image clone requires image format to be "
"'raw' but image {0} is '{1}'").format(
url, image_meta['disk_format'])
This fix solved problem in my setup. RAW images use properly snapshot
and clone function of CEPH.
Best regards,
KK
