Thanks for the response Ben!
Here's the test process:

I was chatting with a kind fellow on the IRC channel that pointed me to
this link:
https://github.com/openvswitch/ovs/blob/master/rhel/README.RHEL#L204
I hadn't considered the need to create startup scripts for the patch
interfaces. Once I did that, they would come back up consistently! As far
as the libvirt vnet interfaces auto-rejoining a bridge upon it being downed
and brought back up, he gave me some ideas to work with on that as well. If
anyone has any ideas that have worked for them on this, I'm all ears!
Thanks!
