"-display none" should not be tangled up with whether we create a monitor or a serial terminal; it should purely and only disable the graphical window. Changing its behaviour like this breaks command lines which, for example, use semihosting for their output and don't want a graphical window, as they now get a monitor they never asked for. It also breaks the command line we document for Xen in docs/system/i386/xen.html: $ ./qemu-system-x86_64 --accel kvm,xen-version=3D0x40011,kernel-irqchip=3D= split \ -display none -chardev stdio,mux=3Don,id=3Dchar0,signal=3Doff -mon char= 0 \ -device xen-console,chardev=3Dchar0 -drive file=3D${GUEST_IMAGE},if=3D= xen qemu-system-x86_64: cannot use stdio by multiple character devices qemu-system-x86_64: could not connect serial device to character backend 'stdio' When qemu is compiled without PIXMAN, by default the serials aren't muxed with the monitor anymore on stdio. The serials are redirected to "null" instead, and the monitor isn't set up.
