I've just installed Debian GNU/Hurd 2023 again, using a simpler Qemu script with IDE disk and cdrom.
It works without problem
This is my script, using a 20G qcow image.
MEMORY=2G
FILE=$HOME/hurd_qemu/hurd2.img
#CDROM=Descargas/debian-sid-hurd-i386-DVD-1.iso
CDROM="$HOME/Descargas/debian-hurd-2023-i386-NETINST-1.iso"
# If I ever need to add a cdrom
echo "running ssh"
qemu-system-i386 -s -m $MEMORY \
-hda $FILE \
-cdrom $CDROM \
-smp 8 \
-boot d \
-net user,hostfwd=tcp:127.0.0.1:2222-:22 \
-net nic,model=e1000 \
-enable-kvm \
-no-shutdown \
-no-reboot \
-vga std \
-display gtk;
#+END_SRC
Maybe the Sergey problem can be in the image's big size, so much bigger than the mine, but i'm not sure.
If I got time, I will try to install in real hardware, to check if there are any problem there.
I expect that info are useful
