You have to use a serial console. These systems you are emulating do not have graphics at all as far as I know. This seems to work for me: qemu-system-arm -M vexpress-a15 -k de -m 512 -device virtio-blk-device,drive=disk1 -drive file=jessie-armhf.img,if=none,id=disk1 -device virtio-net-device,netdev=net0 -kernel vmlinuz -initrd initrd.gz -append "console=ttyAMA0" -name "jessie-armhf" -dtb vexpress-v2p-ca15-tc1.dtb -netdev user,id=net0 -serial stdio -monitor tcp:localhost:4444,server,nowait -nographic -device virtio-blk-device,drive=disk2 -drive file=iso-drive.img,if=none,id=disk2 I created a second disk, formatted it, and copied the netinst iso into it so the installer can find it. Seems to work. You could use telnet or something else for the -serial device that might work better (hitting control-c kills qemu which might be inconvinient, but using tcp and telnet I had no working cursor keys so that didn't help either). I uysed virtio for network and disk since it is much much faster than using SD emulation. The disk appears as /dev/vdX in that case. -- Len Sorensen
