It looks like your configuration: physical NICs do not have IP, the
virtual bonding does:
$ ifconfig
bond0 Link encap:Ethernet HWaddr 00:0C:29:76:C2:C2
inet addr:192.168.2.104 Bcast:192.168.2.255
inet6 addr: fe80::20c:29ff:fe76:c2c2/64 Scope:Link
...
eth1 Link encap:Ethernet HWaddr 00:0C:29:76:C2:C2
inet6 addr: fe80::20c:29ff:fe76:c2c2/64 Scope:Link
...
eth2 Link encap:Ethernet HWaddr 00:0C:29:76:C2:CC
inet6 addr: fe80::20c:29ff:fe76:c2c2/64 Scope:Link
...
And the log is full of
error on subcontainer 'ia_addr' insert (-1)
error on subcontainer 'ia_addr' insert (-1)
