+Probleem: referenties in ovs naar devices die niet meer bestaan. Hij probeert vervolgens een nieuw device aan te maken  met een qdisc op zo'n niet bestaande device.
+
+```
+sudo grep -r 'could not open network device' /var/log/openvswitch/ | grep -oi 'tap[a-z0-9\-]*' | uniq > ports_no_device
+```
+```
+sudo ip l l | grep ports_no_device | grep -oi 'tap[a-z0-9\-]*' > ports_with_device
+```
+```
+for P in $(cat ports_no_device | grep -v -f ports_with_device); do sudo ovs-vsctl del-port $P; done
+```
+```
+sudo systemctl restart ovn-controller
+```
+
+
+Rutger versie:
+```
+sudo grep 'could not open network device' /var/log/openvswitch/ovs-vswitchd.log | grep -oi 'tap[a-z0-9\-]*' | sort | uniq | while read dev; do ip l l $dev || sudo ovs-vsctl del-port $dev; done; sudo systemctl restart ovn-controller
+```
+
+
+Dus: ovs-vsctl del-port is nice.
+
+Niet vergeten ovn-controller te herstarten.
