Thanks to the help of "Dejan Jocic <[email protected]>" and to this answer I manage to get the output of the guest redirected in the terminal by using the following command: PS C:\qemu> clear; & 'C:\Program Files\qemu\qemu-system-x86_64.exe' -hda debian.img -cdrom debian-9.5.0-amd64-netinst.iso -boot d -m 1024 -nographic -kernel vmlinuz -append 'console=ttyS0,115200n8 DEBIAN_FRONTEND=text priority=low' -initrd initrd.gz As you can see it is done on Windows and when attempting to install Debian the output is a bit mest up: Choose the next step in the install process: 1: Choose language [*], 2: Access software for a blind person using a braille display, 3: Configure the keyboard, 4: Detect and mount CD-ROM, 5: Load installer components from CD, 6: Change debconf priority, 7: Check the CD-ROM(s) integrity, 8: Save debug logs, 9: Execute a shell, 10: Abort the installation, Prompt: '?' for help, default=1> 1 Select a language ----------------- Choose the language to be used for the installation process. The selected language will also be the default language for the installed system. Language: ←[22A←[M←[22BPrompt: '?' for help, default=2> ← Looks like it is character encoding related. I understand that it is Windows/powershell but if anyone has a hint, that would be awesome! :) Note that this e-mail is folded by my mailer. -- John Doe
