A virtualization server allows you to run multiple machines, virtual machines (VMs), on one physical device, also known as the host. In a commercial production system, these virtualization servers will often run similar VMs, but for us with homelabs, there could be many different VMs each for different tasks. One VM could be for development work, another could be handling HEVC encodes to save valuable storage, others might be hosting an NGINX reverse proxy and web servers. In this guide, we will discuss configuring your Proxmox virtualization server to use VLANs so that you can group related VMs onto their own subnet.
