The virtual network diagram represents how Proxmox can handle a setup with multiple departments. All the connections between servers and users' virtual machines happen virtually without a physical network device. Using virtual bridges and vNICs, both the administrative and accounting departments can coexist on the same Proxmox cluster. Since all computing happens in the hypervisor, end users can have thin workstations to minimize cost significantly. Users can connect to their virtual machines with remote protocols, such as SPICE, VNC, or RDP.

In this setup, all servers and user machines are virtualized. If there is a need for a new server, it is just a matter of creating a virtual server with vNIC with a few clicks. In such a scenario, all virtual machines can simply be migrated to another available Proxmox node, and everything is up and running in minutes. Both the departments in our example are separated by two virtual bridges.

Through the use of the Proxmox GUI, all management can be done from one location, including backup and restore. Virtual servers can be migrated over network links, which can be spread over large or small physical distances. Although a virtual network setup is much more robust and feature-rich, it has a much lower budgetary requirement. New departments can be added by creating new virtual bridges for separate subnets and using virtual LANs or VLANs on existing physical network switches.
