Description of problem: If 'Use Bridge' option is selected while configuring network (RHEV-H TUI > NETWORK > Configure eth0) of a system which has only 1 pNIC will fail to register with rhevm with error 'configNetworkError: (21, "interface 'eth0' already member of network 'breth0'") in vdsn-reg.log Version-Release number of selected component (if applicable): RHEV-H 6.5 How reproducible: Always Steps to Reproduce: 1. install RHEV-H on a system. 2. While configuring the network (eth0), select 'use bridge ' option 3. try to register the host with the manager Actual results: Registration fails with error shown in attached screenshot Expected result: Successful registration of the host.

Can you please attach the vdsm registration logs and network layout ( ifconfig, brctl show..etc) of the system ? _validateInterNetworkCompatibility() supposed to allow only below combinations. - single non-VLANed bridged network - multiple VLANed networks (bridged/bridgeless) with only one non-VLANed bridgeless network The 'iface_ne't is filled with "breth0" which is non vlan'd and the condition fails.. def _validateNoDirectNet(ifaces): # validate that none of the ifaces # is a non-VLANed network over our iface for (iface_net, iface_vlan) in ifaces: if iface_vlan is None: raise ConfigNetworkError(ne.ERR_BAD_PARAMS, 'interface %r ' 'already member of network %r' % (iface, iface_net)) ifaces_bridgeless = tuple(ni.getBridgelessNetworksAndVlansForIface(iface)) ifaces_bridged = tuple(ni.getBridgedNetworksAndVlansForIface(iface)) # If non-VLANed bridged network exists # we can't add nothing else _validateNoDirectNet(ifaces_bridged) afiact , the only nic (eth0) available in the system is part of 'breth0' bridge at start and _validateNoDirectNet() failed on above mentioned condition and thus the bootstrap failure..
Comment 2 looks like a vdsm problem.
With which RHEV-M are you trying to register? AFAIR, "use bridge" is useful only for legacy rhev-m <= 3.1 which require a pre-existing bridge attached to the physical nic.
Please reopen when you provide the information requested in comment 2 and comment 5.
