Since Linux commit f663b5b38fff trimming vfat is now supported by Linux. This broke the test which assumed it was not supported. Use another filesystem (minix) which does not support trimming instead. Thanks: Daniel P.

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 shouldn't die if sparsifying a filesystem that contains read-only LVs. https://bugzilla.redhat.com/show_bug.cgi?id=1185561 I thought about trying to make the LV writable temporarily, but I suspect that if the sysadmin has made the LV read-only, then they probably did it for a reason, so we shouldn't touch it.

The first patch is just some simple refactoring. See the second patch for a description of the new virt-sparsify --tmp option. I tested this using a loopback device as my temporary block device, and it seems to work fine for me. Federico .. this needs a BZ :-) Rich.

Make use of the helper provided by Tools_utils.create_standard_options, so there is no need to implement the logic in each tool. This affects all the OCaml tools with --machine-readable, namely: virt-builder, virt-builder-repository, virt-dib, virt-get-kernel, virt-resize, virt-sparsify, and virt-v2v. --- builder/cmdline.ml | 8 ++------ builder/repository_main.ml | 6 ++----

Hi! This question emerged during testing of oVirt sparsify integration. oVirt now is able to run virt-sparsify on VM disks. But virt-sparsify seems to have no effect on iSCSI disks. Does virt-sparsify work on iSCSI disks? Maybe in sum situation, with some configuration of iSCSI server, with some specific virt-sparsify options? Shmuel

Make use of the additional command line arguments, and API needed to decrypt LUKS partitions. This affects only virt-customize, virt-get-kernel, virt-sparsify, and virt-sysprep, as they are the main OCaml tools interacting with user-provided images. --- customize/customize_main.ml | 5 ++++- customize/virt-customize.pod | 12 ++++++++++++ get-kernel/get_kernel.ml | 5 ++++-

This still isn't working at the moment. See: http://marc.info/?t=139457409300003&r=1&w=2 This set of patches: - Adds new APIs to support discard in libguestfs. - Adds discard support to virt-format. - Adds discard support to virt-sysprep. - Implements virt-sparsify --in-place. Rich.
