[sudo] password for inovatech: virt-sparsify: warning: There may not be enough free space on /tmp.
You may need to set TMPDIR to point to a directory with more free space.

Max needed: 320.0G.  Free: 2.9G.  May need another 317.1G.

Note this is an overestimate.  If the guest disk is full of data
then not as much free space would be required.

You can ignore this warning or change it to a hard failure using the
--check-tmpdir=(ignore|continue|warn|fail) option.  See virt-sparsify(1).
