Comment 5 for bug 1918734

Yes, exact, there is an IP because it call for host as a context for the ssh_exec function, this host is then translated by linux using the /etc/hosts file, which use an incorrect IP as we have set the migration_interface on the globals.yml file, var that we use on libvirt/nova config template files, but as in here the resolve doesn't come from a direct IP usage but from the python calling linux gethostbyip(host) function then it end up using the /etc/host that we actually do provision within the baremetal role to use api_internal subnet.
