Public bug reported:

I created a server group with anti-affinity policy:

$ os server group create test-group --policy anti-affinity -fvalue -cid
10573804-7127-426d-be6b-409fb5968735

Created four servers as members:

$ os server create --flavor $FLAVOR \
                   --image $IMAGE \
                   --network $NET \
                   --hint group=10573804-7127-426d-be6b-409fb5968735 \
                   --max 4 \
                   test-server

Chose one server randomly and tried to live-migrate it to a host hosting
another member of the group:

$ os server group show 10573804-7127-426d-be6b-409fb5968735 -fvalue -cmembers | \
     tr -d ' ' | tr , '\n' | \
     xargs -n1 -P0 openstack server show -fvalue -cOS-EXT-SRV-ATTR:host
HOST1
HOST2
HOST3
HOST4

$ os server show 2edd275c-9f60-4191-a295-aaa0354f27b2 -fvalue -cOS-EXT-SRV-ATTR:host
HOST1

$os --os-compute-api-version 2.60 \
    server migrate --host HOST2 \
                   --live-migration \
                   --wait \
                   2edd275c-9f60-4191-a295-aaa0354f27b2
Complete

$ os server show 2edd275c-9f60-4191-a295-aaa0354f27b2 -fvalue -cOS-EXT-SRV-ATTR:host
HOST1

This is fairly misleading since nothing actually happens (rightfully),
but the migrate commands doesn't give any indication of that fact.

The environment:
