If you try to make a snapshot and that you get the following error message : Unable to create new logical volume with no extents Simply list the active logical volumes using this command : lvdisplay  If you see in the list a logical volume that corresponds to your snapshot, you can simply delete it with the following command : lvremove /dev/YOUR_PATH/YOUR_LV_NAME

Today I got an error while trying to delete a VirtualBox snapshot : "Failed to delete the snapshot XXXX of the virtual machine YYYY" (english) "Échec de la suppression de l'instantané XXXX de la machine virtuelle YYYY" (french) Hard disk 'XXXX.vdi' has more than one child hard disk (2). In the snapshot manager, there were only two snapshots linked to my virtual machine. I could delete the newest one, but I was not able to delete the oldest one/root snapshot. To resolve this issue, I went to the "File > Virtual Media Manager" menu, then the [Hard Disks] tab and I've expanded the tree under my virtual machine. I've deleted one snapshot that was not linked to any virtual machine, or snapshot. After what I was able to delete my oldest/root snapshot.
