virt-sparsify

Make virtual machine drive images thin-provisioned. Note: Use only for offline machines to avoid data corruption. More information: https://manned.org/virt-sparsify.

• Create a sparsified compressed image without snapshots from an unsparsified one:

virt-sparsify --compress {{path/to/image.qcow2}} {{path/to/new_image.qcow2}}

• Sparsify an image in-place:

virt-sparsify --in-place {{path/to/image.img}}

• Convert from one image format to another:

virt-sparsify {{path/to/image}} --convert {{qcow2|raw|vdi|...}} {{path/to/new_image}}
