I want to give SeaBIOS as bios in my guest OS in Qemu. When I do the same for Linux, there is no problem. However, when I try to wake up a Windows machine with the same BIOS, I get a blue screen error. Error Code: 0xc0000225 as follows.

(The command I used is: qemu-system-x86_64 \
-bios /PATH/seabios/out/bios.bin \
-m 8G \
-enable-kvm \
-smp 4 \
-drive file=/PATH/VM.qcow2,format=qcow2,if=virtio \
-boot c \
-device virtio-vga \
-display none \) This command works when I give a Linux machine, but it doesn't work in Windows. I also add the -drive .iso option for Windows, but it still doesn't work, why?
 
Here is support for PVE.
Have you got the original .conf ?

BTW, Windows doesn't like some HW modifications.
original conf of what? i cloned seabios and just build with make. I did not do anything. So i think yes i got the original conf.
 
then you are wrong here.
this is a support forum for proxmox virtual environment, not random qemu executed on ubuntu. for that you would need to go to the apropriate forums for qemu.
noone here will be able to help you if you arent using the product.
