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

Thanks for the feedback, I think my description was a bit clumsy, but at
least someone confirms that he has seen this...
I still hope it's linked to unfinished VM "Custom Compatibility Version"
updates, tomorrow I'll know, when I finally can do the last VM reboots.
My "Administration Portal" is still usable, but nevertheless I think
this is something the upstream developers should look into.

Regards
Matthias
