Hi,
It looks like that's the issue:
# cat /var/lib/libvirt/dnsmasq/osc_mgmt.hostsfile
52:54:00:2c:85:92,192.168.80.1,openstack-controller-00
But it makes me wonder...libvirt should be generating and managing this file right? Do I need to edit this myself or should libvirt be updating this file? If so then why isn't it?

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 52:54:00:e2:4b:25,192.168.80.2,openstack-database-00 52:54:00:50:91:04,192.168.80.3,openstack-keystone-00 52:54:00:fe:5b:36,192.168.80.7,openstack-rabbitmq-00 52:54:00:95:ca:bd,192.168.80.5,openstack-glance-00

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:===========root@openstack-database-00:/home/osc# ifup ens11 Internet Systems Consortium DHCP Client 4.3.3Copyright 2004-2015 Internet Systems Consortium.All rights reserved.For info, please visit https://www.isc.org/software/dhcp/ Listening on LPF/ens11/...Sending on LPF/ens11/...Sending on Socket/fallbackDHCPDISCOVER on ens11 to 255.255.255.255 port 67 interval 3 (xid=0x6769e42a)DHCPREQUEST of 192.168.80.27 on ens11 to 255.255.255.255 port 67 (xid=0x2ae46967)DHCPOFFER of 192.168.80.27 from 192.168.80.254DHCPACK of 192.168.80.27 from 192.168.80.254bound to 192.168.80.27 -- renewal in 1407 seconds.Some additional info about the VM and network it's attached to===========[root@dragon dnsmasq]# virsh domiflist openstack-database-00Interface Type Source Model MAC------------------------------------------------------- vnet12 bridge br20 virtio 52:54:00:6c:ce:b9vnet13 network VM_MGMT rtl8139 52:54:00:7d:ca:87vnet14 network osc_mgmt rtl8139 52:54:00:e2:4b:25[root@dragon dnsmasq]# virsh net-info osc_mgmtName: osc_mgmtUUID: d93fe709-14ae-4a0e-8989-aeaa8c76c513 Active: yesPersistent: yesAutostart: yesBridge: osc_mgmt===========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.
