This tutorial is for Debian users who want to create network bridges, or virtual switches, on production hosts. These bridges can be used to pass traffic upstream to virtual appliances of all types. In the different bridge scenarios I cover in this tutorial, the intent is to pass traffic to Debian VMs which either run services for my business infrastructure and/or direct services for clients (usually some form of web hosting). I have two production servers:
Each of these machines uses virsh+qemu and have little or no public services listening. The primary and nearly exclusive role of these machines are to run/manage the virtual appliances within them. I typically run virsh+qemu and run VMs for a variety of services such as but not exclusive to private clouds, websites, mail servers, relays, etc. For this reason, it's imperative that the networking setups be solid and that I have good documentation of them. Each location, however, has a different set of requirements due to how they broadcast IP/prefixes, whether they filter traffic or not, and how they allocate IPs.
