[Qemu-devel] [PATCH 0/5] Remove old MigrationParams

[Juan Quintela <quintela@redhat.com>]

Hi

Changes from v4:
- make suggested logic change by eric
- remove extra space in error message
- allow migrate_set_capability block off when block migration is complied off
  (eric request)

Please review

[v4]

- Address Markus review
  * better documentation messages (thanks)
  * reorganize error checking to have small data
  * Use g_new0
  * Improve commints messages

[v4]

- patch 1 included again. We have a 'block' capability and a
  'block_incremental' parameter
  Make Dave happy: rename shared into incremental
  Make Eric and Markus happy:

    block: off -> no block migration, we don't care about
                  block_incremental value
    block: on block_incremental: off -> no incremental block migration
    block: on block_incremental: on  -> incremental block migration

- Use visitors.
  You ask if there is not a better way than hand coding a boolean parser.
  QAPI people (a.k.a. Markus) answer to use a visitor.
  Once there, I used it also for integers, not only booleans.

- Use -b/-i parameters.  OK, I bit the bullet: You can't use
  capabilities/parameters and -b/-i: it gives you one error If you use
  -b/-i, capability parameter is cleanup after the migration ends (Who
  would have guessed that there are cases where we call
  migration_fd_error(), but not migration_fd_cleanup()
  I think this should make Peter and Markus and Dave happy.

- Integrate migrate block compile time disabling
  Well, it conflicted left and right, so I fixed it
  Once there, I disable setting/getting block capability if it is disabled.

[v3]

- Patch 1 included in pull request
- disable block_shared when we disable block_enable
- enable block_enabled when we enable block_shared

[v2]

- make migrate_block_set_* take a boolean
- disable block migration in colo to maintain semantics.

[v1]
Upon a time there were MigrationParms (only used for block migration)
and then MigrationParams used for everything else.  This series:

- create migration capabilities for block parameters
- make the migrate command line parameters to use capabilities
- remove MigrationParams completely


Dr. David Alan Gilbert (1):
  block migration: Allow compile time disable

Juan Quintela (4):
  hmp: Use visitor api for hmp_migrate_set_parameter()
  migration: Create block capability
  migration: Remove use of old MigrationParams
