Hello I have a situation with a vm in which I cannot delete the snapshot. The whole thing is quite strange because I can delete the snapshot when I create and delete it from the web interface but when I do it with a python script through the API it failes. The script does create snapshot-> download snapshot-> delete snapshot and I used the examples from ovirt python sdk on githab to create it ,in general it works prety well. But on a specific machine (so far) it cannot delete the live snapshot Ovirt is 4.3.10 and the guest is a windows 10 pc. Windows 10 guest has 2 disks attached both on different fc domains one on an ssd emc and the other on an hdd emc. Both disks are prealocated. I cannot figure out what the problem is so far the related engine log: 2021-08-03 15:51:00,385+03 INFO [org.ovirt.engine.core.bll.snapshots.RemoveSnapshotSingleDiskLiveCommandCallback]
