The month follows the guest through a migration.\n- ### Limits from guest, plan or default\n\nA guest override wins over its plan, a plan over the global default. Count incoming, outgoing or both.\n- ### A warning at 80 percent\n\nOne email, an inbox alert and a guest event before the limit is reached.\n- ### Notify, throttle or suspend\n\nAt the limit the guest is only reported, throttled to a set speed, or shut down. Resellers can set their own throttle speed.\n- ### Undone automatically\n\nA new month, \"Lift for this month\" or extra gigabytes that bring usage under the limit restore the speed or start the guest again.\n- ### Visible to customers\n\nCustomers see their usage on the server page. A traffic-suspended server cannot be started from the portal, admins and the API still can."},{"heading":"Why not just use the Proxmox web UI?","content":"Proxmox VE runs the virtualization.
