[ovs-discuss] The Open vSwitch kernel module is probably not loaded.

[Cristina Palomo Regidor]

Hello,
I have installed openvswitch in sles 11 sp3 running:
./configure
make
make install

But when I reach this point I receive following error:

sccf1-dell1:~ # ovs-vswitchd --pidfile --detach
2013-09-09T09:40:56Z|00001|reconnect|INFO|unix:/usr/local/var/run/openvswitch/db.sock: connecting...

2013-09-09T09:40:56Z|00003|dpif_linux|ERR|Generic Netlink family 'ovs_datapath' does not exist. The Open vSwitch kernel module is probably not loaded.
2013-09-09T09:40:56Z|00004|dpif|WARN|failed to enumerate system datapaths: No such file or directory


Then, after this error I have tried to run configure with the following options:
% ./configure --with-linux=/lib/modules/`uname -r`/build

And when I do make I receive following error:

Could you help me how to solve the error of module not loaded?

Thanks and BR/
