Hi Antoni,
yes, I'm able to reproduce the issue with
vdsm-4.11.0-24.git5814541.fc18.x86_64.

INFO:root:Removing network ovirtmgmt with vlan=None, bonding=None,
nics=['em1'],options={}
Traceback (most recent call last):
  File "/usr/share/vdsm/configNetwork.py", line 667, in <module>
    main()
  File "/usr/share/vdsm/configNetwork.py", line 642, in main
    delNetwork(bridge, **kwargs)
  File "/usr/share/vdsm/configNetwork.py", line 356, in delNetwork
    _removeUnusedNics(network, vlan, bonding, nics, configWriter)
  File "/usr/share/vdsm/configNetwork.py", line 259, in _removeUnusedNics
    ifup(nic)
  File "/usr/share/vdsm/netconf/ifcfg.py", line 742, in ifup
    rc, out, err = _ifup(iface)
  File "/usr/share/vdsm/netconf/ifcfg.py", line 731, in _ifup
    out[-1] if out else '')
ConfigNetworkError: (29, '')

attached the output of ifup using bash -xv
you'll see a line of '-' separating stdout from stderr.

the bridge was created with the following command:

configNetwork.addNetwork(
            network=bridge,
            nics=[nic],
            force=False,
            bridged=True,
            BOOTPROTO='dhcp',
            ONBOOT='yes',
            blockingdhcp='true',
        )

the remove command is:

/usr/share/vdsm/delNetwork ovirtmgmt '' '' em1 && service network restart
