Hi,
We checked that issue and found out that you are right and this extra
logging lines problem is caused by "next run configuration" improvements
added to oVirt 4.3.5.

The current behaviour is that for each running VM with next run
configuration existed, a warning line of "....Field 'xxx' can not be
updated when status is 'Up'" appears in log, per each vm device and
whenever the vms list is refreshed.
This definitely may flood the engine log if there are few such VMs.

Can you please file a bug on that?

Thanks,
Sharon
