Installing Debian using serial console error 'Undefined video mode'

[john doe <johndoe65534@mail.com>]

Debians,

I'm trying to troubleshoot what I'm doing rong when trying to install
Debian through serial console.

If I start a Qemu VM like so:

qemu-system-x86_64 -cdrom debian-bullseye-DI-alpha2-amd64-netinst.iso
-nographic -vga none -m 1024

At the Debian install prompt pressing the escape key get me to the boot
prompt.

boot: install console=ttyS0,115200n8 DEBIAN_FRONTEND=text gfxpayload=text
Undefined video mode number: 314
Press <ENTER> to see video modes available, <SPACE> to continue, or wait
30 sec


If I use 'vga=none' the above is suppressed but Debian will not start
properly after installation by saying that 'vga=none' is deprecated and
that 'set gfxpayload=text' should be used instead.

What am I missing?
