RHEV-H 6.5

How reproducible:
Always 

Steps to Reproduce:
1. install RHEV-H on a system.

Comment 2 Humble Chirammal 2013-12-09 05:09:57 UTC

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.

Comment 5 Dan Kenigsberg 2014-02-12 12:17:25 UTC

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.
