Hi Team, we have created a bond with name bond-mgmt for the provisioning n/w and passed that name as local interface: Undercloud.conf: *..* *..* *# Network interface on the Undercloud that will be handling the PXE* *# boots and DHCP for Overcloud instances. (string value)* *local_interface = bond-mgmt* *..* *..* Because of this undercloud deployment is getting failed with the error as below: [root@localhost ~]# ovs-vsctl show b3db7071-58f7-4201-8fd5-9577dec0020e Bridge br-ctlplane fail_mode: standalone Port bond-mgmt Interface bond-mgmt error: "could not open network device bond-mgmt (No such device)" Port br-ctlplane Interface br-ctlplane type: internal ovs_version: "2.12.0" [root@localhost ~]# Query: - is bonding supported in Undercloud installation for provisioning n/w? - if yes then what is the correct way to do so. we are trying to deploy Train on Centos 8. -- ~ Lokendra skype: lokendrarathour
