Hi all, I'm trying to fiddle with virtio driver in kvm on ARM, but I can't get QEMU to start. When I try to start it as so: qemu-system-arm -enable-kvm -M vexpress-a9 -drive file=/arm-wheezy.img,if=virtio -append 'root=/dev/mmcblk0 console=ttyAMA1 rootwait earlyprintk' -kernel /zImage-guest -nographic it complains about a missing PCI bus: qemu-system-arm: -drive file=/arm-wheezy.img,if=virtio,cache=writeback: No 'PCI' bus found for device 'virtio-blk-pci' Do I need to reconfigure QEMU, or is there something wrong with my invocation?
