(Note: The problem and solution I'll describe here are not libvirt-specific, but since I asked the question here I thought it best to provide the answer too.) In the preseed file I was using for the installer, I had placed a line I'd copied from Ubuntu's example configuration: d-i partman-auto/disk string /dev/sda The virtio_blk driver was ready to be used, but I was still telling the installer to use the non-virtio device. Installation to the virtio block device succeeded after I replaced that line with this one: d-i partman/early_command string debconf-set partman-auto/disk "$(list-devices disk | head -n1)" -- Brian
