Title:
block device mapping transformation doesn't handle "image" source
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
I hit this while implementing volume snapshots for the NFS Cinder
driver. I booted an instance from an image with the destination as a
volume.
nova boot --block-device id=fc19829e-5f65-4e9c-
acf3-0e898747506f,source=image,dest=volume,size=2,bootindex=0,shutdown=preserve
...
Creating a volume snapshot for this case will run down
_volume_refresh_connection_info in LibvirtDriver, which fails in
DriverVolumeBlockDevice's _transform, which only allows 'volume' as a
source type.
It looks to me like this code should allow 'image' as a source, but
I'm not an expert in this area in Nova...
