I would have expected to see output such as this: supermin: internal insmod virtio.ko It seems as if you might not be setting SUPERMIN_MODULES; or maybe you don't have any modules that match the internal list in supermin: <a href="https://github.com/libguestfs/supermin/blob/master/src/ext2_initrd.ml#L33" target="_blank">https://github.com/libguestfs/supermin/blob/master/src/ext2_initrd.ml#L33</a> Anyhow, virtio-scsi definitely isn't working, as you can see from the appliance kernel output. You can force the direct backend to use virtio-blk instead by editing the function src/launch-direct.c: qemu_supports_virtio_scsi. <div class="im HOEnZb"> Rich. -- Richard Jones, Virtualization Group, Red Hat <a href="http://people.redhat.com/~rjones" target="_blank">http://people.redhat.com/~rjones</a> Read my programming and virtualization blog: <a href="http://rwmj.wordpress.com" target="_blank">http://rwmj.wordpress.com</a> </div><div class="HOEnZb"><div class="h5">virt-df lists disk usage of guests without needing to install any software inside the virtual machine.
