   > Is this for volume or VM snapshots @Slair1 ? - as volume snapshots are NOT possible for KVM while the VM is running (someone thought that's interesting to do that, due to qcow2 safety...so now it's useless for KVM...)
   
   It is for volume snapshots, but you're correct the global setting kvm.snapshot.enabled needs to be enabled.  But this brings up another point, we are wondering if we need to do a suspend before deleting VM Snapshots also.  From our examination of the code, it looks like both VM Snapshots and Volume Snapshots use the save libvirt libraries to take and delete the snapshot... so I would think they could both have the same corruption issue if the snapshot is deleted while the VM is powered-on and not suspended during the snapshot delete...
