I do not quite understand the problem you describe.

Does the problem go away if you set your network to "non-required"? If
your VM's app does not strictly require unintermitant networking, just
set the networ to non-required.  Flipping the default of requiredness
can be considered only for 4.0 ("required" was our default since ever,
other users' scripts may depend on that).

Could you attach Vdsm and Engine logs to the bug? How was the host
fenced?
