On controller:

# make rpm-fedora-kmod

ALL nodes:

openvswitch-2.6.90-1.el7.centos.x86_64.rpm

Only Controller:

# rpm -i openvswitch-ovn-common-*.x86_64.rpm# rpm -i
openvswitch-ovn-central-*.x86_64.rpm

Only Compute:

# rpm -i openvswitch-ovn-common-*.x86_64.rpm# rpm -i
openvswitch-ovn-host-*.x86_64.rpm

# lsmod | grep open
     - shows all the required modules

Let me know if you need anything else.

Thanks.
