[Qemu-devel] [PATCH 0/6] qmp: Add blockdev-mirror


From: Fam Zheng

This is the counterpart of blockdev-backup. The biggest value of this command
is to allow full flexibility on target image open options, via blockdev-add.
For example this could help solve the target provisioning issue in:

Because mirror job uses bdrv_swap, this series depends on Max's BlockBackend
series:

    [PATCH v3 00/38] blockdev: BlockBackend and media
    http://lists.nongnu.org/archive/html/qemu-devel/2015-06/msg01109.html

which makes it possible for blockdev-add to insert a BDS without BB (by
omitting "id=" while only specifying "node-name=").
