The reason for these error messages is that by default Open vSwitch assumes
that a kernel based datapath is being created, which it cannot do if the
kernel module is not loaded.  If you look at the next line in the
INSTALL.userspace directions you'll see:

ovs-vsctl set bridge br0 datapath_type=netdev

The "netdev" datapath type corresponds to userspace, so the errors should go
away once you give it that command.  Since the kernel module is our primary
datapath you may see a few additional error messages about not being able to
contact it but you can safely ignore those.
