Shutdown the VM and add this to the vmx file and then restart the VM, if the host OS is Linux:
serial0.present = “true”
serial0.fileType = “device”
serial0.fileName = “/dev/ttyS0”
If host is Windows:
serial0.present = “true”
serial0.fileType = “device”
serial0.fileName = "COM1"
这里的设备名称取决运行vm的主机的操作系统，所以设备名称也来自这个操作系统的命名方式。
