Dear OpenNebula Team, i did the Upgrade from 5.12 to 6.2 some days ago. In 5.12 - after a vm LIVE Migration (kvm), the snapshot revert & deletion was not functional anymore for some older snapshots. Now in 6.2 - at least the revert seems to work after a LIVE Migration for older snapshot, but not the deletion of them: QEMU-IMG INFO: [root@sunstone]# qemu-img info /mnt/datastores/mynfsstorage/0/90/disk.0.snap/0 (nfs ACCESS to the DATASTORE IS FUNCTIONAL from sunstone,also from the hypervisor node(s)) file format: qcow2 virtual size: 200 MiB (209715200 bytes) disk size: 208 MiB cluster\_size: 65536 backing file: /var/lib/one/datastores/1/904ddf2ecf6d85e6d6ecbe73de574ba7 backing file format: qcow2 Snapshot list: ID TAG VM SIZE DATE VM CLOCK ICOUNT 3 snap-0 39.5 MiB 2022-04-07 20:03:39 00:08:56.748 4 snap-1 39.4 MiB 2022-04-07 20:04:45 00:10:02.273 5 snap-2 39.4 MiB 2022-04-07 20:05:44 00:10:59.789 6 snap-3 39.4 MiB 2022-04-07 20:06:29 00:11:43.933 7 snap-4 38.3 MiB 2022-04-18 11:38:35 00:01:29.011 Format specific information: compat: 1.1 compression type: zlib lazy refcounts: false refcount bits: 16 corrupt: false extended l2: false HOTPLUG REVERT OK after LIVE\_MIGRATION: Mon Apr 18 12:03:39 2022 [Z0][VM][I]: New LCM state is RUNNING Mon Apr 18 12:04:56 2022 [Z0][VM][I]: New LCM state is HOTPLUG\_SNAPSHOT Mon Apr 18 12:04:56 2022 [Z0][VMM][I]: VM Snapshot successfully reverted.
