Thanks, but I found issue in your guide :) We need mount drive as VirtIO, so we need to specify `root=/dev/vda` and `-drive file=$HOME/linux/qemu/image/bookworm.img,format=raw,if=virtio` without it I had kernel panic Thanks, David On 2/28/26 11:53, Siddh Raman Pant wrote:

How you recommend to test kernel? I use Arch and found 3 ways: * Native run, replace existing kernel * Qemu with full Linux distribution, install Ubuntu in qemu and replace kernel in it * Minimal Qemu, need to create initramfs with busybox and connect to Qemu with your kernel, but I even couldn't see printk log from e1000e in this way Option 3 is the best way since you can't keep rebooting your machine when you reproduce crashes.

I did a writeup about it, it might help you. Take a look here: https://bodha.siddh.me/posts/2023/10/14/kernel_qemu_setup/

Thanks, Siddh

If you followed the guide, I don't think that's true.

Unless something has changed in upstream since I wrote it.

Thanks, Siddh

It seems that I forgot about your `common.config` :) I've added it and recompile kernel, but I have kernel panic again because disk On 2/28/26 21:56, Siddh Raman Pant wrote:

What are the options are you using?

Just the error is unhelpful.

Again, if you followed the guide I don't think this should happen. I specifically mentioned that error there.

Thanks, Siddh
