Hi,

This new migration parameter allows mapping block node names and bitmap
names to aliases for the purpose of block dirty bitmap migration.

This way, management tools can use different node names on the source
and destination and pass the mapping of how bitmaps are to be
transferred to qemu (on the source, the destination, or even both with
arbitrary aliases in the migration stream).

v1 (as opposed to the RFC):
- Added an iotest
- Allow mapping of not only node names, but also of bitmap names to
  aliases
- Make this a migration parameter instead of adding a whole new QMP
  command
- Added patch 1 for good measure


Max Reitz (4):
  migration: Prevent memleak by ...params_test_apply
  migration: Add block-bitmap-mapping parameter
  iotests.py: Add wait_for_runstate()
  iotests: Test node/bitmap aliases during migration
