+serial/parallel character devices created for the none-machine
+
+The none-machine can not be started unless using "-serial null":
+
+qemu-system-x86_64 -machine none -nographic -monitor stdio
+QEMU 3.1.1 monitor - type 'help' for more information
+(qemu) qemu-system-x86_64: cannot use stdio by multiple character devices
+qemu-system-x86_64: could not connect serial device to character backend 'stdio'
+$
+
+$ qemu-system-mips -machine none -nographic -serial null -monitor stdio
+QEMU 4.1.50 monitor - type 'help' for more information
+(qemu) info chardev
+parallel0: filename=null
+compat_monitor0: filename=stdio
+serial0: filename=null
+(qemu)
+
+You can start 'none' without "-serial null". Examples:
+
+qemu-system-x86_64 -machine none
+qemu-system-x86_64 -machine none -monitor stdio
+qemu-system-x86_64 -machine none -nographic
+qemu-system-x86_64 -machine none -monitor stdio -display none
+
+Your command line "qemu-system-x86_64 -machine none -nographic -monitor stdio" fails because "-nographic" says "please create a serial port using stdio" but "-monitor stdio" tries to use stdio for something else. You get the same message for any machine (eg "pc"), not just "none". If what you wanted was "just don't create the graphical display" that's "-display none" -- "-nographic" is a collection of things including both 'no display' and also 'default to creating a serial device to stdio' and 'default to creating a monitor muxed with that serial'.
