This is weird. I just tried creating an stretch image and it worked both under autopkgtest and booting it with plain kvm. In a shell (from autopkgtest --shell): ~# cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-4.9.0-8-amd64 root=UUID=ca8c4a47-0074-4a85-bb10-610e9672bf86 ro biosdevname=0 net.ifnames=0 consoleblank=0 systemd.show_status=true rw quiet systemd.show_status=false quiet loglevel=3 rd.systemd.show_status=false systemd.show_status=false console=tty0 console=ttyS0,115200n8 console=ttyS0 > However, fstab is also wrong: > > | # cat /etc/fstab > | /dev/sda1 / ext4 errors=remount-ro 0 1 > > There is no sda1, this is virtio and thus it's vda1.

It is created by us, but maybe that should be implemented by vmdb2.
