I guess a kernel space OVS instance is already running on your system. To
completely remove OVS from a linux system use the following commands:
kill `cd /usr/local/var/run/openvswitch && cat ovsdb-server.pid
ovs-vswitchd.pid`
rmmod openvswitch
rm -rf /usr/local/etc/openvswitch
rm -rf /usr/local/var/run/openvswitch
The "rmmod openvswitch" command should remove the kernel module. Then try
re-installing OVS without the kernel modules:
./boot.sh
./configure
make
make install
mkdir -p /usr/local/etc/openvswitch
ovsdb-tool create /usr/local/etc/openvswitch/conf.db
vswitchd/vswitch.ovsschema
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
ovs-vsctl --no-wait init
ovs-vswitchd --pidfile --detach
