[Rdo-list] overcloud update [external - float interface name]

I have been deployed my overcloud via: ### openstack overcloud deploy --compute-scale 4 --templates --compute-flavor compute --control-flavor control ### the baremetal server interfaces naming is as enoX X == {1,2,3,4} I also have connected all baremetal servers eno1 directly into undercloud eth1 as management zone Now I wana create external network for float ip assignment via: ### neutron net-create ext-net --router:external --provider:physical_network datacentre --provider:network_type flat ### the datacentre is directlly connected to the public ip address router, but the problem is that I don't have such and interface name in OS level... is seem's I should have to solution: 1- rename Controller eno2 -> datacentre 2- update overcloud and don't know how but force it to know [ eno2 ] instead of [ datacentre ] :-? solution 1 ( os level interface renaming ) seems to be a bit distructive... cos centos wiki's told we should edit kernel param at grub and revert to old interface naming also stick to udev rules and alike... I pereferer to know how can I update my overcloud to accept eno2 instead of datacentre? thanks
