Description Mike Kolesnik 2012-05-31 03:47:53 EDT
Description of problem:
Attempted to setupNetworks to change bond from 2 to 3 nics with the command:
MainProcess|Thread-135::DEBUG::2012-05-31 08:33:39,906::configNetwork::998::setupNetworks::(setupNetworks) Setting up network according to configuration: networks:{}, bondings:{'bond4': {'nics': ['eth1', 'eth2', 'eth3'], 'BONDING_OPTS': 'mode=802.3ad miimon=150'}}, options:{'connectivityCheck': 'true', 'connectivityTimeout': '60000'}

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create bond over two bonds
2. Run setup networks to add another bond
Actual results:
Got exceptions:

  File "/usr/lib64/python2.7/multiprocessing/managers.py", line 773, in _callmethod
    raise convert_to_error(kind, result)
KeyError: '_networks'

Expected results:
Bond should be defined over the 3 interfaces.

Additional info:
This will probably happen when changing bond from 3 to 2 nics, but haven't tested that.
