Hello,

I just rechecked everything. Result is the same. I have included all of the steps used for testing:

[root@centos-ovs-build-06-00-00-6b-df-48 x86_64]# rpm -qplf openvswitch-kmod-1.9.0-1.el6.x86_64.rpm

/lib/modules/3.4.36-6.el6.centos.alt.x86_64/kernel/extra/openvswitch/brcompat.ko
/lib/modules/3.4.36-6.el6.centos.alt.x86_64/kernel/extra/openvswitch/openvswitch.ko

[root@centos-ovs-build-06-00-00-6b-df-48 openvswitch-1.9.0]# lsmod | grep openvswitch
[root@centos-ovs-build-06-00-00-6b-df-48 openvswitch-1.9.0]# insmod /lib/modules/3.4.36-6.el6.centos.alt.x86_64/kernel/extra/openvswitch/openvswitch.ko

[root@centos-ovs-build-06-00-00-6b-df-48 openvswitch-1.9.0]# dmesg

*snip*

openvswitch: Open vSwitch switching datapath 1.9.0, built May 10 2013 14:02:24

[root@centos-ovs-build-06-00-00-6b-df-48 x86_64]# /etc/init.d/openvswitch start

[root@centos-ovs-build-06-00-00-6b-df-48 x86_64]# ovs-vsctl show
57b8b736-96dd-4e20-820b-e45228611685

Now create bridges and patchport:

ovs-vsctl add-br xenbr0-int

ovs-vsctl add-br xenbr0-tun

ovs-vsctl add-port xenbr0-int xenbr0-int-patch-tun
ovs-vsctl set interface xenbr0-int-patch-tun type=patch
ovs-vsctl set interface xenbr0-int-patch-tun options:peer=xenbr0-tun-patch-int
ovs-vsctl add-port xenbr0-tun xenbr0-tun-patch-int
ovs-vsctl set interface xenbr0-tun-patch-int type=patch
ovs-vsctl set interface xenbr0-tun-patch-int options:peer=xenbr0-int-patch-tun

[root@centos-ovs-build-06-00-00-6b-df-48 x86_64]# ovs-vsctl show

[root@centos-ovs-build-06-00-00-6b-df-48 x86_64]# ovs-vsctl get Interface xenbr0-tun-patch-int ofport

kmod package was built using the following:

rpmbuild -bb -D "kversion 3.4.36-6.el6.centos.alt.x86_64" openvswitch-kmod-fedora.spec where openvswitch-kmod-fedora.spec is the spec file included in the tarball under /rhel/.

Double-check everything. You probably do not have the right version
of the kernel
module loaded.
