Hello

I can't remove checkpoints. I will be backing up to a new NAS device.

virsh checkpoint-list vm1

I removed all checkpoints and opened them again but it still says there is a checkpoint.

cd /var/lib/libvirt/qemu/checkpoint/vm1
ls -l
virtnbdbackup.0.xml
virtnbdbackup.1.xml
virtnbdbackup.2.xml
virtnbdbackup.3.xml
rm -rf *

remove checkpoint using virsh utility, with --metadata option.
Removing files will not delete checkpoints at libvirt api.
