It would appear so (tbh, I'm more familiar with OvS-DPDK than the kernel datapath). In this case 'system' is the datapath type, and 'ovs-system' is a network device associated with the datapath's local port - take a look at http://openvswitch.org/support/dist-docs/ovs-dpctl.8.txt for more information: "Most ovs-dpctl commands that work with datapaths take an argument that specifies the name of the datapath. Datapath names take the form [type@]name, where name is the network device associated with the data‐ path's local port." > >Best wishes! >________________________________________ >[email protected] > >From: Kavanagh, Mark B >Date: 2017-03-29 16:54 >To: ???; ovs-discuss >Subject: RE: [ovs-discuss] Issue: rmmod: ERROR: the Module openvswitch is in >use >> >>Hi everyone, >>I'm asking for assistance to fix this issue:“rmmod: ERROR: Module openvswitch >>is in use” >> >>I found unloading openvswitch.
