Thanks for your comments.

The error while building kernel modules was as follows

% ./boot.sh
% ./configure --with-linux=/lib/modules/`uname -r`/build | grep error
configure: error: source dir /lib/modules/2.6.32-71.el6.x86_64/build doesn't exist

I checked  source dir and kernel sources had been removed in server.
So, I downloaded the latest kernel and compiled it.

Now, there is no error in configure.
But, there are some errors in building kernel module as follows.

% make

make  all-recursive

If you let me know how to fix it, it will be very helpful to me.

Thanks

Did you get any errors while building the .ko module.  What is the output of make install.
Did u install the kernel headers. Where exactly they are located. Sometimes they will take
different path rather than /lib/modules/...

Hi,

I am installing openvswitch 1.7..1 package on the CentOS 6.0
(kernel ver: 2.6.32-71.el6.x86_64, gcc ver: 4.4.6)
I have done the following with the instructions in INSTALL.Linux,

% ./boot.sh
% ./configure --with-linux=/lib/modules/`uname -r`/build
% make
% make install
% insmod datapath/linux/openvswitch.ko
insmod: can't read 'datapath/linux/openvswitch.ko': No such file or directory

openvswitch.ko is not in the datapath/linux directory, so I guess
I didn't build the kernel module correctly.

I wonder what’s wrong in the kernel building process.

Thanks,
