By default, GNOME Boxes and virt-manager VM's, do not enable block device discards. So this feature is a 'no op' in that case. And also fstrim.service won't run in a container. I've updated the feature to reflect these two things. I'm not certain what the default should be for VMs. I really only ever use libvirt managed qemu-kvm these days, so I'm also not sure what the defaults are elsewhere for comparison. -- Chris Murphy _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org
