Hi all, The image created by debootstrap does not work in the qemu
I use the following script to generate one image: ---------------------------------------------------------------- IMG=qemu-stretch.img DIR=mount-point.dir #qemu-img create -f qcow2 $IMG 5G qemu-img create $IMG 5G sudo mkfs.ext4 $IMG mkdir $DIR sudo mount -o loop $IMG $DIR sudo debootstrap --arch amd64 stretch $DIR sudo umount $DIR rmdir $DIR ---------------------------------------------------------------- The commented line in the above script will get error when you create image by "qcow2" format. Then I use the following command to run this image: qemu-system-x86_64 -kernel /boot/vmlinuz-4.12.0-1-amd64 -hda qemu-stretch.img -append "root=/dev/sda1 single" However, the result shows that "VFS: unable to mount root fs". I learn the method from the following website: https://www.collabora.com/news-and-blog/blog/2017/01/16/setting-up-qemu-kvm-for-kernel-development/ By the way, I use Debian Testing as my host operating system.
