Subject: [PATCH] Fix infinite boot loop on headless system in qemu
|
|
|
|
After finishing headless virtual machine installation via serial
|
|
console, the reboot fails in grub with infinte boot loop and also
|
|
keyboard input for serial console is unresponsive.
|
|
|
|
The cause of infinte loop boils down to legacy vga driver in grub
|
|
crashes when '-dispaly none' is used as qemu's display type described in
|
|
the manual as:
|
|
|
|
"Do not display video output. The guest will still see an emulated
|
|
graphics card, but its output will not be displayed tothe QEMU user.
|
|
This option differs from the -nographic option in that it only affects
|
|
what is done with video output; -nographic also changes the destination
|
|
of the serial and parallel port data."
|
|
|
|
Given there's no sensible way found to skip the emulated device from the
|
|
legacy vga module, we ended up removing it from all_video dependency so
|
|
it wouldn't be loaded by default. In any case, the vbe module remain
|
|
loaded and should fulfill the requirement of most hardwares even twenty
|
|
years old or more.
|
|
|
|
The unresponsive serial input is also fixed by ensuring that console
|
|
input is loaded via appended so that they won't fail altogether with
|
|
errors by other console device if specifying on the same list.
