FWIW, I have tried, and my VMs with thin LV storage are working fine, even though the libvirt storage pool barfs on the VG. (bz924672) > Is using LVs for this over-thinking things? One nice aspect with thin LVM snapshots is you don't need to worry about preserving the chain of origin. There's no backing file except the main thinpool itself. One can snapshot to arbitrary depths, and delete old images anywhere, freeing the unique blocks but keeping whatever is still shared. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
