Hi Alper. That was the trick!
It looks like a progress. `console=tty0` added in the grub to linux line. And it works, the first ~25 seconds there is a black/blank screen, and qemu says "Guest disabled this display". It eventually does switch to framebuffer, and the X.org server for graphical install starts too (but in a bit weird resolution, which appears to be 1348 × 656 pixels). The text mode installer also work really well over virtio-gpu-pci. I used this command line: qemu-system-aarch64 -m 8192 -M virt,acpi=on -cpu max -smp 2 -device qemu-xhci,id=usb -usb -device usb-kbd -device usb-tablet -device virtio-gpu-pci -display default,show-cursor=on -drive if=virtio,format=raw,readonly=on,media=cdrom,file=debian-testing-arm64-netinst.iso -bios /usr/share/qemu-efi-aarch64/QEMU_EFI.fd (Using -cdrom debian-testing-arm64-netinst.iso instead, also works fine). The only minor issues, is that the majority of initial kernel messages go to serial console only, and none to frame buffer. I.e. first 22 seconds of messages go to serial console only. It is reasonable, but a bit different than on x86. PS. Adding extra `-device VGA` causes Xorg to be confused, and not know which framebuffer to use). PS2. After that, I got hit with the virtio storage not detected, but that is the issue on all architectures that I know (I did hit this previous on alpha for example), like reported in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=689528 , and the workaround posted there also works. PS3. Then I got hit by kernel module mismatch between my iso and the network repository, but that is known issue with debian installer snapshots. Thanks Alper.
