Are extra guest kernel components needed too? (I'm using 3.9.9-302.fc19.armv7hl but could try a later kernel) Anyway, I tried to get it to work, but can't quite work out the qemu command line. So far I have: $ ~/d/qemu/arm-softmmu/qemu-system-arm -M vexpress-a15 -cpu cortex-a15 \ -nographic -kernel kernel -initrd initrd \ -drive file=root,if=virtio \ -append "root=/dev/vda" qemu-system-arm: -drive file=root,if=virtio: No 'PCI' bus found for device 'virtio-blk-pci' Any suggestions?
