qemu on Debian 9 has some issues showing the curses console when running a Debian 9 guest. To fix this the guest's grub needs to supply some extra parameters to the kernel and disable a module:

  • on the guest system open /etc/default/grub and add console=tty0 console=ttyS0 to GRUB_CMDLINE_LINUX this tells the linux kernel to use tty0 as console
    • note: see info -f grub -n 'Simple configuration' for difference between GRUB_CMDLINE_LINUX and GRUB_CMDLINE_LINUX_DEFAULT
  • create (or change the file) /etc/modprobe.d/bochs_drm.conf so that its contents is the following line: install bochs_drm /bin/true
    • note: this configures modorobe to run /bin/true instead of loading bochs_drm, which disables the loading of
    • note: install is a modprobe command (not the shell command!), whereas /bin/true is a shell command.
You can’t perform that action at this time.
