The context here is that the ovn devstack plugin compiles and loads the openvswitch kernel module from the ovs source tree. It has to do this as OVN depends on openvswitch kernel features in upstream kernel version 4.3. Those features have been backported to the version of the module in the ovs tree which we can use on older kernels. This error occurs when the devstack plugin runs: sudo modprobe -r openvswitch Try: lsmod | grep openvswitch The far right column will list any other kernel modules that depend on the openvswitch module. Those have to be unloaded first. ovs-vswitchd shouldn't be running, as it should have been uninstalled earlier in devstack, but that's something to check for. If nothing else, if it's just a dev VM, try rebooting. -- Russell Bryant __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
