[ovs-discuss] ovs 2.3 kernel module build failed on rhel 7.0 GA

[Gang U Xu]

Yes, In fact, I reboot the whole system after I upgrade kernel.

Below for your reference

[root at vs260 ~]# rpm -qa  | grep kernel-
kernel-tools-3.10.0-123.8.1.el7.x86_64
kernel-devel-3.10.0-123.8.1.el7.x86_64
kernel-3.10.0-123.8.1.el7.x86_64
kernel-3.10.0-123.el7.x86_64
kernel-devel-3.10.0-123.el7.x86_64
kernel-headers-3.10.0-123.8.1.el7.x86_64
kernel-debug-devel-3.10.0-123.8.1.el7.x86_64
kernel-tools-libs-3.10.0-123.8.1.el7.x86_64


The steps below:
1. Upgrade kernel
2. Reboot the system
3. Cherry-pick commit, and generate patch
4. rpm build,

BTW, for you mentioned bootstrap the tree.
I did not know how to do?
Do you have detailed info or link I can follow?
Thanks!

Did you also yum update the kernel-devel and kernel-header?

Also, you may need to backport this 
patch, ba119c1371f2579dc412855a46b533e442210f4d

Not sure about the specific steps you did, but I think you need to
bootstrap the tree (./boot) again to make the changes effective.
