I did another experiment and got the same result. I have included the system
logs in this case - perhaps it is informative?
Running the following instructions on the latest git clone of the OVS
repository:
./boot.sh
./configure --with-linux=/lib/modules/`uname -r`/build
make
make install
touch /usr/local/etc/ovs-vswitchd.conf
mkdir -p /usr/local/etc/openvswitch
mkdir -p /usr/local/var/run/openvswitch/
touch /usr/local/etc/ovs-vswitchd.conf
ovsdb-tool create /usr/local/etc/openvswitch/conf.db vswitchd/vswitch.ovsschema
ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock \
--remote=db:Open_vSwitch,Open_vSwitch,manager_options \
--private-key=db:Open_vSwitch,SSL,private_key \
--certificate=db:Open_vSwitch,SSL,certificate \
--bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert \
--pidfile --detach
ovs-vsctl --no-wait init
ovs-vswitchd --pidfile --detach
ovs-vsctl add-br br1 -- set bridge br1 datapath_type=netdev
ovs-vsctl add-port br1 p1 -- set interface p1 ofport_request=1 --
ovs-vsctl add-port br1 p2 -- set interface p2 ofport_request=2 --
ovs-vsctl show
I get these system logs:

Cannot explain why ports p1 and p2 are not added to br1. Any help would be
greatly appreciated!
