[ovirt-users] Host "Unassigned Logical Networks" list is wrong

Hi, I'm having a special issue with assigning logical networks to host interfaces via label. I'm used to assigning logical networks (tagged VLANs, VM network flag) a "Network label", which I can choose from a drop down menu in the UI dialog. These networks are automatically flagged "assign" and "require" in my cluster and I expect them to be synced to hosts physical interface to which I "drag and dropped" the label. This always seemed to work and I never worried. Now I noticed that when I look at the host "Setup Host Networks" dialog again, that the last(?) logical networks I provisioned as explained above show up as "Unassigned Logical Networks" with a mouse over text of "Network should be assigned to 'foo' via label 'bar'. However for some reason it isn't". This has to be some presentation error, because the networks are in fact assigned which is also visible in the hosts "Network Interfaces" tab. The "Sync All Network" buttons in "Host" - "Network Interfaces" and "Cluster" - "Logical Networks" tabs are inactive. When hosts are put to maintenance and activated again the error disappears. My oVirt version is 4.3.7. Cluster switch type is "Linux Bridge". This may seem a minor error, but since it affects my production clusters and a couple of VLANs I can't afford to play around with host network configuration. Can anybody explain this? Any help would be appreciated. thx Matthias
