Thanks flaviof, As your email thread, I can't use the option
"force-reload-kmod" to uninstall the openvswitch.ko.
The error was always shown " modprobe: FATAL: Module openvswitch is in use."
My operation is as below:
1. insmod openvswitch.ko
modprobe openvswitch
2. start the ovsdb-server:
ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock
--remote=db:Open_vSwitch,Open_vSwitch,manager_options
--private-key=db:Open_vSwitch,SSL,private_key
--certificate=db:Open_vSwitch,SSL,certificate
--bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert --pidfile --detach
3. start ovs-vswitchd
ovs-vswitchd --pidfile --detach
4. add a ovs bridge
ovs-vsctl add-br br0
5. remove this bridge
ovs-vsctl del-br br0
until this step3, I can successful uninstall openvswitch.ko and no error shown
with command: modprobe -r openvswitch
but, step 5, the error " modprobe: FATAL: Module openvswitch is in use." is
shown when I want to remove the kernel mode of openvswitch, in spite of
stopping ovs with "pkill ovs".
I have found the virtual interface named "ovs-system" with command " ifconfig
-a", I guess it is the key of this issue. So what can I do to remove the
"ovs-system"?
Thanks
Zhiwei xiong

Also, see if this is related to a known issue that was discussed here [1].
I never got look at the code that Jesse suggested [2]; sorry!
