|
|
|
|
The IsolatedHostsFilter checks for images restricted to certain hosts via
|
|
config options. When creating a server from a root volume, the image is
|
|
in the volume (and it's related metadata from Cinder). When creating a
|
|
volume-backed server, the imageRef is not required.
|
|
|
|
The regression is that the RequestSpec.image.id field is not set and the
|
|
IsolatedHostsFilter blows up trying to load the image id.
