For the curiosity sake - 

After some trial and error.  It appears we have solved one half of our conundrum.  Using the driver below, there is no ip data inserted into libvirt.xml which allows any ip to be used.  It works for our uses (HA vip services, secondary addresses).

libvirt_vif_driver=nova.virt.libvirt.vif.LibvirtOpenVswitchVirtualPortDriver 

This however does not prevent quantum from assigning a used IP to a new port, but working on that.

Libvirt's driver only supports 1 ip per interface. It needs to be updated to use the newer network models and not depend on the code in nova.virt.netutils.get_injected_network_template.

Happy Hacking!
