Hello, I've installed oVirt 4.3.2 and the problem is that it log messages: VDSM ovirt-04 command Get Host Statistics failed: Internal JSON-RPC error: {'reason': '[Errno 19] genev_sys_6081 is not present in the system'} in Open Virtualization Manager. It also keeps on logging in /var/log/messages: Mar 22 11:51:03 ovirt-04 NetworkManager[8725]: <info> [1553244663.9861] device (genev_sys_6081): carrier: link connected Mar 22 11:51:03 ovirt-04 NetworkManager[8725]: <info> [1553244663.9864] manager: (genev_sys_6081): new Generic device (/org/freedesktop/NetworkManager/Devices/34160) Mar 22 11:51:03 ovirt-04 NetworkManager[8725]: <info> [1553244663.9866] device (genev_sys_6081): enslaved to non-master-type device ovs-system; ignoring Mar 22 11:51:03 ovirt-04 NetworkManager[8725]: <info> [1553244663.9906] device (genev_sys_6081): enslaved to non-master-type device ovs-system; ignoring Mar 22 11:51:03 ovirt-04 kernel: device genev_sys_6081 left promiscuous mode Mar 22 11:51:04 ovirt-04 kernel: device genev_sys_6081 entered promiscuous mode Mar 22 11:51:04 ovirt-04 NetworkManager[8725]: <info> [1553244664.0038] device (genev_sys_6081): carrier: link connected Mar 22 11:51:04 ovirt-04 NetworkManager[8725]: <info> [1553244664.0042] manager: (genev_sys_6081): new Generic device (/org/freedesktop/NetworkManager/Devices/34161) Mar 22 11:51:04 ovirt-04 NetworkManager[8725]: <info> [1553244664.0044] device (genev_sys_6081): enslaved to non-master-type device ovs-system; ignoring Mar 22 11:51:04 ovirt-04 NetworkManager[8725]: <info> [1553244664.0082] device (genev_sys_6081): enslaved to non-master-type device ovs-system; ignoring Mar 22 11:51:04 ovirt-04 kernel: device genev_sys_6081 left promiscuous mode Mar 22 11:51:04 ovirt-04 kernel: device genev_sys_6081 entered promiscuous mode Also I can see the following in /var/log/openvswitch: 2019-03-22T08:53:12.413Z|131047|bridge|WARN|could not add network device ovn-034a1c-0 to ofproto (File exists) 2019-03-22T08:53:12.431Z|131048|tunnel|WARN|ovn-a21088-0: attempting to add tunnel port with same config as port 'ovn-0836d7-0' (::->192.168.10.24, key=flow, legacy_l2, dp port=2) 2019-03-22T08:53:12.466Z|131055|connmgr|WARN|accept failed (Too many open files) 2019-03-22T08:53:12.466Z|131056|unixctl|WARN|punix:/var/run/openvswitch/ovs-vswitchd.9103.ctl: accept failed: Too many open files In ovsdb-server.log: 2019-03-22T03:24:12.583Z|05792|jsonrpc|WARN|unix#28684: receive error: Connection reset by peer 2019-03-22T03:24:12.583Z|05793|reconnect|WARN|unix#28684: connection dropped (Connection reset by peer) How to fix this issue with geneve tunnels?
