+ qemu: Open backing chain late for shallow block copy reusing external images
+ </summary>
+ <description>
+ With introduction of -blockdev specification of storage for qemu VMs
+ in libvirt-5.10 we've started opening the backing chain of the
+ destination/mirror of a virDomainBlockcopy started with
+ VIR_DOMAIN_BLOCK_COPY_REUSE_EXT | VIR_DOMAIN_BLOCK_COPY_SHALLOW flags
+ when starting the job rather than when virDomainBlockJobAbort with
+ VIR_DOMAIN_BLOCK_JOB_ABORT_PIVOT is issued. For users depending on
+ this undocumented quirk this caused a regression in behaviour as
+ the backing chain could not be modified while the copy of the top
+ image was progressing. Note that this fix also requires qemu-5.0 while
+ -blockdev is used starting from qemu-4.2.
