Re: [Libguestfs] [PATCH v6] v2v: Add --print-estimate option to print copy size estimate.

This option prints the estimated size of the data that will be copied from the source disk. Currently this overestimates by the size of the qcow2 header, but for real disk images that doesn't matter much. For example: $ virt-builder fedora-27 $ virt-v2v -i disk fedora-27.img -o null --print-estimate [...] virt-v2v: This guest has virtio drivers installed.
