+
+    Before change I4244f7dd8fe74565180f73684678027067b4506e in Stein, when
+    a cold migration would reschedule to conductor it would not send the
+    RequestSpec, only the filter_properties. The filter_properties contain
+    a primitive version of the instance group information from the RequestSpec
+    for things like the group members, hosts and policies, but not the uuid.
+    When conductor is trying to reschedule the cold migration without a
+    RequestSpec, it builds a RequestSpec from the components it has, like the
+    filter_properties. This results in a RequestSpec with an instance_group
+    field set but with no uuid field in the RequestSpec.instance_group.
+    That RequestSpec gets persisted and then because of change
+    Ie70c77db753711e1449e99534d3b83669871943f, later attempts to load the
+    RequestSpec from the database will fail because of the missing
+    RequestSpec.instance_group.uuid.
+
+    This test recreates the regression scenario by cold migrating a server
+    to a host which fails and triggers a reschedule but without the RequestSpec
+    so a RequestSpec is created/updated for the instance without the
+    instance_group.uuid set which will lead to a failure loading the
+    RequestSpec from the DB later.
