The guide here at Foswiki is very accurate and applies for Oracle Linux 6 UEK kernel as well. I'm also including my steps below for reference as well.
The system that OpenvSwitch will be built on is described and characterized below. Note that this is an Oracle Linux UEK kernel system.
[root@oracle67 SOURCES]# uname -a

[root@localhost ~]# python -V

This puts python2.7 in /opt/rh/python27. It won't be used unless you "source" the enable script.
[root@oracle67 ~]# python -V
Python 2.6.6
[root@oracle67 ~]# source /opt/rh/python27/enable
[root@oracle67 ~]# python -V

Next cd to the ~/rpmbuild/SOURCES directory and get the tarball as shown below.
[root@oracle67 SOURCES]# cd ~/rpmbuild/SOURCES
[root@oracle67 SOURCES]# wget http://openvswitch.org/releases/openvswitch-2.5.0.tar.gz

We can then unpack the tar-ball so we can get the needed .spec files for use with rpmbuild as shown below.
[root@oracle67 SOURCES]# tar -zxvf openvswitch-2.5.0.tar.gz
You have to edit the openvswitch.spec file as shown below to use "python27" where indicated. The bolded line shows how it should look after the edit with "python27" in the requires line.
[root@oracle67 rpmbuild]# cd SPECS/

[root@oracle67 SPECS]#
Now build the rpms as indicated below.
source /opt/rh/python27/enable
cd ~/rpmbuild/SPECS
rpmbuild -ba openvswitch.spec
Now the rpm is built if the above steps went well as shown below.
[root@oracle67 x86_64]# ls -lrt
total 12056
-rw-r--r--. 1 root root 3012436 Aug 3 19:16 openvswitch-2.5.0-1.x86_64.rpm
-rw-r--r--. 1 root root 9329736 Aug 3 19:16 openvswitch-debuginfo-2.5.0-1.x86_64.rpm
[root@oracle67 x86_64]#
Now install the rpm as shown below. If you get any messages about python version be sure you have sourced and verified that python 2.7 is in use.
[root@oracle67 x86_64]# yum localinstall openvswitch-2.5.0-1.x86_64.rpm
Now create the openvswitch db and reboot. It may be necessary to first create the
[root@localhost x86_64]# cd /usr/local/etc
[root@localhost etc]# which ovsdb-tool
/bin/ovsdb-tool
[root@localhost etc]# ls -lrt
total 0
[root@localhost etc]# pwd
/usr/local/etc
[root@localhost etc]# mkdir openvswitch
[root@localhost etc]# ovsdb-tool create /usr/local/etc/openvswitch/conf.db
[root@localhost etc]#
After reboot, check that ovs-vsctl shows good status as shown below.
[root@oracle67 x86_64]# sudo ovs-vsctl show
0b9b0d61-3f3a-40bc-a250-81d1b0502cf4
ovs_version: "2.5.0"
[root@oracle67 x86_64]#
