The network node hosts network services such as DHCP, DNS, and so on for each virtual network. These services need to communicate with the other members on the virtual network. The network node runs an OVS instance to connect to the virtual network.
In this recipe, we will look at the DHCP service running on the Network node and identify the virtual network interface, which connects this service to the virtual network.
For this recipe, you will need the following information:
The SSH login credentials for the controller and network node
The following steps will show you how to identify an interface connecting a network service to the virtual network. In this recipe, we will look at the network interface for the DHCP service:
Log in to a node with access to OpenStack.
Next, we will find the DHCP server process that is associated with our virtual network. OpenStack uses
dnsmasq
