To be able to boot a disk image, passed to QEMU with `-hda
/path/qemu.img`, the appropriate modules are needed. Strange, `libata`
is not enough, and the drive is only detected, when the module `ahci` is
loaded.
> ata1.00: ATA-7: QEMU HARDDISK, 2.5+, max UDMA/100
Tested with QEMU emulator version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7)
with the command below,
qemu-system-x86_64 -enable-kvm -M q35 -m 1G -bios \
qemu-coreboot/coreboot.rom -serial stdio -L /dev/shm -hda \
/dev/shm/qemu-debian.img
where `qemu-debian.img` is created with grml-debootstrap.
grml-debootstrap --vmfile --vmsize 3G --target \
/dev/shm/qemu-debian.img -r sid
