rhel-av-8.5 will use qemu-6.0 which didn't adopt the upstream 'blockdev-reopen' yet, so we'll stick with the downstream version. Moving to 8.6 Verified on libvirt-7.6.0-2.module+el8.5.0+12219+a5ea13d2.x86_64 qemu-kvm-6.0.0-29.module+el8.5.0+12386+43574bac.x86_64:
1.Create checkpoint
# virsh checkpoint-create-as rhel9 c1
Domain checkpoint c1 created
2. Create disk-only snapshot
# virsh snapshot-create-as rhel9 s1 --no-metadata --disk-only --reuse-external
Domain snapshot s1 created
3. Remove checkpoint c1:
# virsh checkpoint-delete rhel9 c1
Domain checkpoint c1 deleted
