[Bug 1619602] [NEW] Hyper-V: vhd config drive images are not migrated

 

You have been subscribed to a public bug:

During cold migration, vhd config drive images are not copied over, on
the wrong assumption that the instance is already configured and does
not need the config drive.

There is an explicit check at the following location:
https://github.com/openstack/nova/blob/8f35bb321d26bd7d296c57f4188ec12fcde897c3/nova/virt/hyperv/migrationops.py#L75-L76

For this reason, migrating instances using vhd config drivers will fail, as there is a check ensuring that the config drive is present, if required:
https://github.com/openstack/nova/blob/8f35bb321d26bd7d296c57f4188ec12fcde897c3/nova/virt/hyperv/migrationops.py#L153-L163

The Hyper-V driver should not skip moving the config drive image.
