+++ This bug was initially created as a clone of Bug #743830 +++
Steps to reproduce:
1) Add network to cluster, with a network-id that doesn't exist in rhevm database, for example:
<network id="2b8efd92-1779-40db-87a4-043f27dd3bc0">
<name>green</name>
</network>
2) Failure at database level (naturally).
3) VdcReturnValueBase object, which is returned, has emtpy executeFailedMessages[] array (the error can be seen only in 'fault' field which is internal).
Expected Results:
VdcReturnValueBase-->executeFailedMessages[] should contain a description of the failure.
