Hello, I have been wanting to learn how to use QEMU for the development of the linux kernel, at the kernelnewbies.org page I did not find any information, in google I found this page: https://www.collabora.com/news-and-blog/blog/2017/01/16/setting-up-qemu-kvm-for-kernel-development/

Following the first examples, it gives me two problems, I hope you can guide me.

$qemu-system-x86_64 -kernel /boot/vmlinuz-`uname -r`

end Kernel panic - not sysncing: VFS: Unable to mount toor fs on unknown-block(0,0)

aku@openSUSE:~> sudo qemu-system-x86_64 -kernel /boot/vmlinuz-`uname -r`
[sudo] password for root:
Unable to init server: Could not connect: Connection refused

Thank you
