Please check the dnsmasq hostsfile, should have all the records there:

# cat /var/lib/libvirt/dnsmasq/osc_mgmt.hostsfile

52:54:00:2c:85:92,192.168.80.1,openstack-controller-00

When attempting to bring up the relevant interface in the virtual machine, I get an incorrect IP address assigned, different from the one I statically set up per the XML above. As you can see, the device with MAC '52:54:00:e2:4b:25' should really be getting 192.168.80.2, but what happens when we bring this interface up is this:

===========

What's strange is that the first VM seems to work correctly and gets an assigned address of 192.168.80.1, but for some reason the others don't. Any ideas?
