Hi, On CentOS 8, when using virt-sparsify for a ntfs image, it does not seem to work. Tried virt-sparsify on Fedora 32 and it works great. Is there some dependent application that need to be installed in CentOS 8 for virt-sparsify to work on ntfs? Here are some information. CentOS 8. # virt-sparsify -V virt-sparsify 1.38.4rhel=8,release=14.module_el8.1.0+248+298dec18,libvirt # virt-sparsify --machine-readable virt-sparsify linux-swap zero check-tmpdir in-place tmp-option Fedora 32. # virt-sparsify -V virt-sparsify 1.42.0fedora=32,release=6.fc32,libvirt # virt-sparsify --machine-readable virt-sparsify linux-swap zero check-tmpdir in-place tmp-option ntfs btrfs Noticed that the Fedora 32 virt-sparsify --machine-readable has ntfs. How to get that on CentOS 8? P.V.Anthony
