This allows sparsifying images during migration where the source + has no access to the allocation state of blocks at the cost of CPU overhead. + + This feature is avaliable via the ``--migrate-disks-detect-zeroes`` option + for ``virsh migrate`` or ``VIR_MIGRATE_PARAM_MIGRATE_DISKS_DETECT_ZEROES_ZEROES`` + migration parameter. See the documentation for caveats. + * **Improvements** * qemu: internal snapshot improvements -- 2.47.0
