[Qemu-devel] [PATCH v6 0/4] Add 'blockdev-snapshot' command |
Date: |
Tue, 22 Sep 2015 16:28:51 +0300 |
v6:
- Update documentation and parameter names following Eric's
suggestions: 'device' -> 'node', 'snapshot' -> 'overlay'.
- Rebased on top of Max's "BlockBackend and media" v5
v5: https://lists.gnu.org/archive/html/qemu-block/2015-09/msg00483.html
- Don't delete the 'backing' option if it contains something different
from an empty string.
- Rebase on top of the current master.
v4: https://lists.gnu.org/archive/html/qemu-block/2015-09/msg00372.html
- Implement the support for 'backing': '', drop 'ignore-backing',
and update iotest 085 accordingly.
- Include sample 'blockdev-add' call in the 'blockdev-snapshot'
documentation.
- Clarify that the snapshot must not have a backing file in the
BlockdevSnapshot documentation.
- Update error message ("...node name already existing" -> "...exists").
v3: https://lists.gnu.org/archive/html/qemu-block/2015-09/msg00272.html
- Add 'ignore-backing' field to BlockdevOptionsGenericCOWFormat. This
allows opening images but not their backing images.
- Check for op blockers in the snapshot node and make sure that it
doesn't have any backing image.
- Remove extra check for the existence of the snapshot node:
bdrv_open() already does that.
- Extend iotest 085 to add tests for 'blockdev-snapshot'.
- Replace local_err with errp in some places where the former is
unnecessary.
- Update command description.
- Add 'since' tag to the 'blockdev-snapshot' field in TransactionAction.
v2: https://lists.gnu.org/archive/html/qemu-block/2015-09/msg00094.html
- Add 'blockdev-snapshot' command instead of allowing passing options
to 'blockdev-snapshot-sync'.
- Rename BlockdevSnapshot to BlockdevSnapshotSync
v1: https://lists.gnu.org/archive/html/qemu-block/2015-08/msg00236.html
Alberto Garcia (4):
block: rename BlockdevSnapshot to BlockdevSnapshotSync
block: support passing 'backing': '' to 'blockdev-add'
block: add a 'blockdev-snapshot' QMP command
block: add tests for the 'blockdev-snapshot' command
