qemu also supports binding the emulated serial port to a telnet server.
Look for the -chardev parameter in the qemu-kvm manual page.( With
proxmox you would  then use the "args: " parameter in vm.conf to specify
extra args )

This would allow you to telnet to your host on a specific port to get a
serial console. As with every telnet traffic remember than nothing is
encrypted, so I would'n t do this in a productive setup.
