Just a general comment: to the extent that others are integrating Open
vSwitch with their hypervisors (e.g. Telivo) we don't have to provide a
generic solution for this but just documentation about what needs to be
set (through ovs-vsctl or whatever) in order for the application they
are using (e.g. NVP) to work. It then becomes their responsibility to
create the solution.
We have to do this for XenServer because we're the ones actually doing
the hypervisor integration work. If we choose to do this for another
platform than we'll do it there and it may make sense to generalize the
solution with hypervisor specific modifications but I'd suggest we wait
to do that work until we've identified the next hypervisor platform
we're going to do the integration work on.
