if you dont mind the kernel
you can start the clockworkpi os v0.21 with qemu and debian net boot kernel
qemu-system-arm -M vexpress-a9 -m 512 -kernel vmlinuz -initrd initrd.gz -dtb vexpress-v2p-ca9.dtb -drive file=./armdisk.raw,if=sd -append "console=ttyAMA0,115200 root=/dev/ram" -serial stdio -net nic,model=lan9118 -net user
just a tip,not fullly tested
