Xorg is not starting, (EE) no screens found(EE)

So I'm developing my LFS system in qemu and everything works properly but now I need a proper screen resolution and I find out for that we need to compile kernel with KVM modules so I did. And then I rebooted and got proper full screen display but after that when I tried to start my KDE with startx, xorg failed to start. And I'm pretty sure I get this error after getting KVM modules because I tried to revert the things and my xorg works again. And it's a virtual machine so I don't even know which graphic drivers I need or where I'm going wrong. Below you will find the xorg log.

LFS Version: 10.1
Kernel Version: 5.10.17
qemu arguments: -m 4G -enable-kvm -cpu host -vga virtio -display sdl,gl=on -smp 4

Any help would be great. Thanks in advance.
