OVN virtual_port is an OVN concept that represents a logical port in the virtual network. A virtual port connects a virtual machine or container to the virtual network, and it can be associated with one or more logical switches. Each virtual port has a unique identifier, and it can have different properties such as MAC address, IP address, security groups, and QoS policies.
OVN virtual ports are created and managed by the OVN Controller, which ensures that the virtual ports are correctly configured and connected to the appropriate logical switches. The OVN Controller uses the OpenFlow protocol to communicate with the virtual switches and configure the necessary flows to enable communication between the virtual machines and containers.
OVN virtual ports also support advanced networking features such as load balancing, NAT, and overlay networks. They can be used to build complex virtual network topologies that span multiple physical hosts and data centers, providing a flexible and scalable solution for modern cloud environments.
