KVM Host Networking Configuration Choices

There are many choices for network configuration in the KVM host. In this topic, four choices are discussed.

The four network configuration choices are:

• Using a Linux® bridge with NAT for KVM guests
• Using a Linux bridge (without NAT) for KVM guests
• Using an Open vSwitch bridge with KVM guests
• Using the MacVTap driver with KVM guests

Each of these choices has trade-offs. In the topics below, each choice will have a topic describing the configuration, and a review that highlights the pros and cons to help you to decide which configuration is best for your needs.
