Ceph doesn't support QCOW2 for hosting a virtual machine disk: http://docs.ceph.com/docs/master/rbd/rbd-openstack/ When we set image_type as rbd and force_raw_images as False and we don't launch an instance with boot-from-volume, the instance is spawned using qcow2 as root disk but fails to boot because data is accessed as raw. To fix this, we raise an error and refuse to start nova-compute service when force_raw_images and image_type are incompatible. When we import image into rbd, check the format of cache images. If the format is not raw, remove it first and fetch it again. It will be raw format now. Change-Id: I1aa471e8df69fbb6f5d9aeb35651bd32c7123d78 Closes-Bug: 1816686

upgrade:
|
|
- |
|
|
The libvirt driver's RBD imagebackend no longer supports setting
|
|
force_raw_images to False. Setting force_raw_images = False and
|
|
images_type = rbd in nova.conf will cause the nova compute service
|
|
to refuse to start. To fix this, set force_raw_images = True. This
|
|
change was required to fix the `bug 1816686`_.
|
|
|
|
Note that non-raw cache image files will be removed if you set
|
|
force_raw_images = True and images_type = rbd now.
