Hi guys, I want to build openvswitch kernel module, and my centos is 6.0, kernel version is 2.6.32-71.29.1.el6.x86_64. But i cannot find the kernel-headers-2.6.32-71.29.1.el6.x86_64. I use the yum command to install kernel-headers package: yum install kernel-headers-2.6.32-71.29.1.el6.x86_64, it says no package available. (BTW My yum repos is coming from http://www.centos.org/modules/tinycontent/index.php?id=30.) Please help me if you have this package, or plz tell me where can find it. Thanks in advanced, Kris
