Doc Type: Bug Fix
Doc Text:
The source IP address for cold migration and resize was previously determined by the default gateway configured on the source compute node. The my_ip option is now explicitly set to the internal_api network IP in nova.conf, ensuring the correct network is used for this traffic.

Comment 5 Joe H. Rahme 2017-11-24 16:54:56 UTC 
Cold migration uses `my_ip` from /etc/nova/nova.conf:


From /etc/nova/nova.conf
------------------------

    [heat-admin@compute-0 ~]$ sudo grep my_ip /etc/nova/nova.conf
    ...
    my_ip=172.17.1.15
    ...
    
From /etc/ssh/sshd
------------------

    Match LocalAddress 172.17.1.15 User nova_migration
        AllowTcpForwarding no
        AuthorizedKeysFile /etc/nova/migration/authorized_keys
        ForceCommand /bin/nova-migration-wrapper
        PasswordAuthentication no
        X11Forwarding no

From /etc/hosts
---------------

    [heat-admin@compute-0 ~]$ sudo grep 172.17.1.15 /etc/hosts
    172.17.1.15 compute-0.localdomain compute-0
    172.17.1.15 compute-0.internalapi.localdomain compute-0.internalapi
