Title:
Wrong image ref after unshelve
Status in compute-hyperv:
Fix Released
Status in OpenStack Compute (nova):
Invalid
Bug description:
After an instance is unshelved, the instance image ref will point to
the original image instead of the snapshot created during the shelving
[1][2].
Subsequent instance operations will use the wrong image id. For
example, in case of cold migrations, Hyper-V instances will be unable
to boot since the differencing images will have the wrong base [3].
Other image related operations might be affected as well.
As pointed out by Matt Riedemann on the patch [1], Nova shouldn't set
back the original image id, instead it should use the snapshot id.
