Hi List.

I am using libvirt 5.6.0, QEMU 4.1.0 on Arch Linux.
When I am trying to create a snapshot of a VM (it has an existing 
snapshot already), no matter which tool I am using (virsh, qemu-img, 
virtviewer) the following error is thrown:

[root@box1 images]# qemu-img snapshot -c snap1 manjaro.qcow2
qemu-img: Could not create snapshot 'snap1': -22 (Invalid argument)

virsh # snapshot-create-as --domain M --name snap1 --description test
Fehler: Interner Fehler: Untergeordneter Prozess (/usr/bin/qemu-img 
snapshot -c snap1 /var/lib/libvirt/images/manjaro.qcow2) unerwartet Ende 
Status 1: qemu-img: Could not create snapshot 'snap1': -22 (Invalid 
argument)


virsh # snapshot-list M

virsh # version
Kompiliert gegen die Bibliothek: libvirt 5.6.0
Verwende Bibliothek: libvirt 5.6.0

Verwende API: QEMU 5.6.0
Laufender Hypervisor: QEMU 4.1.0

Any help is very welcome.

Thanks,
Steffi
