I tested virtfs with the current coreos_production_qemu_uefi.sh, which sets up cloud-config using a virtfs drive. It works as expected. For virtfs to work you need the latest CoreOS kernel [1] (that has CONFIG_VIRTIO_PCI=m), or use qemu's virtio-9p-device driver. Check the kernel with: cat /proc/config.gz | gunzip | egrep '(9P|VIRTIO)' [1] https://github.com/coreos/coreos-overlay/pull/2112 -Geoff
