eth0|10.0.0.30 eth0|10.0.0.50 eth0|10.0.0.51
+-----------+-----------+ +-----------+-----------+ +-----------+-----------+
| [ Control Node ] | | [ Network Node ] | | [ Compute Node ] |
| | | | | |
| MariaDB RabbitMQ | | Open vSwitch | | Libvirt |
| Memcached httpd | | Neutron Server | | Nova Compute |
| Keystone Glance | | OVN-Northd | | Open vSwitch |
| Nova API | | Cinder Volume | | OVN Metadata Agent |
| Cinder API | | iSCSI Target | | OVN-Controller |
