Hi,
Due to network related API changes between the enging and VDSM, cluster
3.1 host agents should be updated:
Starting from ovirt-engine commit
ec5f528e80ac8e7b2d8bb4f65eb46391233fd1fd, VDSM must include commit
1fa30a08b93c5ba76c8f5377d030d8a597023d18.
The expected behaviour without an updated VDSM, is having all 3.1 hosts
as non-operational due to missing networks.
Regards,
Moti
