Ulhas, Pavel: please note that this bug is NOT the same issue of the "vanishing bond" bug 1154399. The our bug 1197668 is about rolling back to manually-configured ifcfg files in case of failure in setupNetworks. In 99% of the cases it is unrelated to rhev-h (where users do not edit ifcfg files manually), and as such, it is not planned to be released in a node image.
