Bondging, Bridging, Vlan-ing, Oh My

[Justin Brown <justin brown fandingo org>]

Coming high off my triumph of configuring an Ethernet NIC with a
bridge using nothing but keyfiles, I figured that I would try
something more complicated.

First off, I'll start by saying that I would normally stick to
network.service or NetworkManager with the ifcfg-rh plugin. However,
for some time, both methods fail to assign IP addresses to bridges.
Fedora 18 and 19 both have this problem, and I've previously hacked
around it by `ifup br0` after boot.

Ok, so here's what I'm trying to do with Fedora 19,
NetworkManager-0.9.8.2-8.git20130709.fc19.

Two physical interfaces (em1, em2), bonded together (bond0), "grab"
VLAN 25 (vlan25), and bridge to libvirt (kg25).

em1, em2 ---> bond0 ---> vlan25 ---> kg25 (192.168.25.10/24)

Before I list the keyfiles, I want to state the results. Almost
everything works, except the vlan25 interface. The physical interfaces
come up, the bond is created and has the proper slaves, and kg25
bridge is created with the proper IP address.

NetworkManager "sees" the connection (nmcli c), but I cannot activate it.

        nmcli c up id vlan25
        Error: Connection activation failed: Failed to determine
connection's virtual interface name

Looking through the journal, this is the only error as well.

I have been using https://fedoraproject.org/wiki/Networking to
configure NetworkManager, and I don't see any issues with my
configuration.

On a separate note, is there any ability to control the miimon value
and bonding mode in NM 0.9.8, or do I need to wait for
Features/NetworkManagerBonding in Fedora 20?


Any help or guidance would be greatly appreciated.

Thanks,
Justin
