In my test scenario(live snapshot), the reproduce ratio is 90%. *** Bug 2051870 has been marked as a duplicate of this bug. *** Verified this bug as below.
Tested with:
qemu-kvm-6.2.0-6.module+el8.6.0+14165+5e5e76ac
kernel-4.18.0-364.el8.x86_64
Steps:
1. Create snapshot over RBD base image
# qemu-img create -f qcow2 -b rbd:rbd/rhel860-64-virtio-scsi.raw -F raw /home/kvm_autotest_root/images/snA.qcow2
2. Boot up guest from the snapshot
