If you like you can check what drivers are supported by the initrd like this: $ virt-builder --arch x86_64 fedora-23 $ virt-get-kernel -a fedora-23.img download: /boot/vmlinuz-4.4.6-300.fc23.x86_64 -> ./vmlinuz-4.4.6-300.fc23.x86_64 download: /boot/initramfs-4.4.6-300.fc23.x86_64.img -> ./initramfs-4.4.6-300.fc23.x86_64.img $ zcat initramfs-4.4.6-300.fc23.x86_64.img | cpio -it | grep virtio usr/lib/modules/4.4.6-300.fc23.x86_64/kernel/drivers/block/virtio_blk.ko.xz usr/lib/modules/4.4.6-300.fc23.x86_64/kernel/drivers/char/hw_random/virtio-rng.ko.xz usr/lib/modules/4.4.6-300.fc23.x86_64/kernel/drivers/char/virtio_console.ko.xz usr/lib/modules/4.4.6-300.fc23.x86_64/kernel/drivers/scsi/virtio_scsi.ko.xz usr/lib/modules/4.4.6-300.fc23.x86_64/kernel/drivers/virtio usr/lib/modules/4.4.6-300.fc23.x86_64/kernel/drivers/virtio/virtio.ko.xz usr/lib/modules/4.4.6-300.fc23.x86_64/kernel/drivers/virtio/virtio_pci.ko.xz usr/lib/modules/4.4.6-300.fc23.x86_64/kernel/drivers/virtio/virtio_ring.ko.xz 51087 blocks Hence that particular guest should support booting from virtio-blk or virtio-scsi.
