Title:
error injecting data into image when launching from volume
Status in OpenStack Compute (Nova):
Triaged
Bug description:
branch: master
commit: ae251b99a3fb6aa99ec8898152d79dfa2c026a92
I launch the instance from a sheepdog volume without specifying an
image when launching.
The following error occurred:

Clearly, nova tries to inject to an image file that doesn't exist on
disk. We may need to skip injecting the data when launching from a
volume.
