Create a serial device inside the VM (n is 0 to 3), and pass through a
host serial device (i.e. /dev/ttyS0), or create a unix socket on the
host side (use 'qm terminal' to open a terminal connection).
NOTE: If you pass through a host serial device, it is no longer possible to migrate such machines -
use with special care.
CAUTION: Experimental! User reported problems with this option.
