Hey,

I have also gone through this problem in my early days with open
vswitch. In this condition, you can do one thing:

Just create a init script for open vswitch and add it into the
services, from init script you can handle the start/stop priority for
open vswitch server during restart/reboot of host server. This might
help you.

Cheers
