In the virt-install example, you try to use volume fd1440.img, which doesn't
show up in the vol-list output, meaning virt-install thinks that file doesn't
exist, hence why it says you need to specify a path

What's the output of ls -l /var/lib/libvirt/images

If the file is actually there, you might need to refresh the pool with 'virsh
pool-refresh default'
