1. You're correct in that I'm looking to provide preseed file. But host-side HTTP server won't work for my needs, unless VirtualBox has it integrated. My technology is aimed at people, who require *zero* configuration, and should work across all hosts. Like click, click, click... Basically I need very minimal (and portable) host-side logic (and move as much complexity into the guest as possible). You said: "Do an "attended install". Verify that reading from floppy is possible. That is important. It proofs that the Virtualbox host provides a "floppy disk controller" and that the Vbox guest has a kernel kernel for the f.d.c. Also it shows there is /dev/fd0 (IIRC)" 2. Well... you'r right ! /dev/fd0 is the problem ! Yes, I ensured, that VM has floppy controller configured, plus floppy.img inserted. Debian 8 (mini-)kernel (inside amd64-DVD) does NOT see /dev/fd0 ! (part of debian-installer); This works just fine with Debian 6 and 7 ! Post-install Debian 8 kernel _does_ see /dev/fd0, can loop-mount and can read files from it. (after installing from Debian 8 amd64-DVD), so no problem here. The natural question: Are those kernels different ? (I always assumed it is the *same* kernel) It seems the mini-kernel does not provide me with "/proc/config.gz", so I have no clue what's included and what's excluded. How can I check ?
