I installed stx with all-in-one on bare metal

reading the guide

sudo ip address add <IP-ADDRESS>/<SUBNET-LENGTH> dev <PORT>
sudo ip link set up dev <PORT>
sudo ip route add default via <GATEWAY-IP-ADDRESS> dev <PORT>
ping 8.8.8.8

becomes

sudo ip link add link eno1 name eno1.861 type vlan id 821
sudo ip address add XXX.XXX.XXX.132/25 dev eno0.821
sudo ip link set up dev eno1.821
sudo ip route add default via XXX.XXX.XXX.129 dev eno1.821
ping 8.8.8.8

and it works

ssh in...

created localhost.yml

playbooks run fine

source /etc/platform/openrc

however

OAM_IF=eno1.821
[sysadmin@localhost ~(keystone_admin)]$ system host-if-modify controller-0 $OAM_IF -c platform
Interface not found: host controller-0 if eno1.821

so how or what did i miss... ???
