commit 6c6ffc0476b56fe0bf822ddcf3c9a2d543912f38 Author: zhu.boxiang <[email protected]> Date: Fri Mar 1 16:16:31 2019 +0800 Fix failure to boot instances with qcow2 format images 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.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1816686 Title: fail to boot an instance because of "rbd import" qcow2 disk Status in OpenStack Compute (nova): Fix Released Bug description: Environment =========== OpenStack: master branch Ceph: luminous Steps to reproduce ================== 1. Upload a qcow2 format image to glance such as a test qcow2 image `cirros`. 2. Use command to create a new instance: `openstack server create <server-name> --image <image-name> --flavor <flavor-name> --security-group <security-group-name> --availability-zone nova --network <network-name>` 3. After instance has been spawn successfully, we run command to get the console url: `openstack console url show <server-name>` 4. Open the browser and enter the console url, I see that the instance fails to boot. Expected result =============== The instance succeeds to boot. Actual result ============= The instance fails to boot. When importing rbd volume from _base image file, the format of image file is qcow2. When using a qcow2 as root disk, the instance is spawned but fails to boot because data is accessed as raw. So try to convent the image format when import it into rbd as raw.
