[Qemu-devel] [PATCH 0/2] Allow to repair broken quorum files

[Benoît Canet]

This patch allow to build a mirror of a block device and replace an arbitrary
named node of the graph with the mirror.

The obvious first usage is Quorum: with this patch one quand drive-mirror the
block device say quorum0 and then bdrv_swap the result in place of a broken
quorum file (dead filer for example).

The second patch implement drive-mirror tests for this mode.

Benoît Canet (2):
  block: Add node-name and to-replace-node-name arguments to
    drive-mirror.
  qemu-iotests: Add TestRepairQuorum to 041 to test drive-mirror
    node-name mode.
