[libvirt-users] Immutable backing files

Hi list, suppose I have an immutable (ie: due to a read-only snapshot) backing file. After creating an overlay file with "qemu-img create -f qcow2 -o backing_file=/path/to/immutable/file.img current.qcow2", libvirt refuse to start the virtual machine and exits with an error stating "Could not open backing file /path/to/immutable/file.img: Permission denied". From my understanding, libvirtd is trying to change the owner/permissions/selinux context of the backing file but, being it immutable, fails to start the VM. Is that the expected behavior?
