[Qemu-devel] [PATCH v3 9/9] qapi: Add transaction support to dirty-bitmap-{add, disable}

This adds dirty-bitmap-add and dirty-bitmap-disable to transactions. With this, user can stop a dirty bitmap, start backup of it, and start another dirty bitmap atomically, so that the dirty bitmap is tracked incrementally and we don't miss any write. Signed-off-by: Fam Zheng --- blockdev.c

[Qemu-devel] [PATCH v3 7/9] qmp: Add dirty-bitmap-enable and dirty-bitmap-disable

This allows to put the dirty bitmap into a disabled state where no more writes will be tracked. It will be used before backup or writing to persistent file. Signed-off-by: Fam Zheng --- block.c | 15 +++ blockdev.c| 44 ++

[Qemu-devel] [PATCH v3 5/9] hbitmap: Add hbitmap_copy

[Qemu-devel] [PATCH v3 1/9] qapi: Add optional field "name" to block dirty bitmap

This field will be set for user created dirty bitmap. Also pass in an error pointer to bdrv_create_dirty_bitmap, so when a name is already taken on this BDS, it can report an error message. This is not global check, two BDSes can have dirty bitmap with a common name. Implemented bdrv_find_dirty_bi

[Qemu-devel] [PATCH v3 0/9] QMP: Introduce incremental drive-backup with in-memory dirty bitmap

Introduction This implements incremental backup. A convenient option "bitmap-use-mode" for drive-backup is introduced since v1. Commands A new sync mode for drive-backup is introduced: drive-backup device=.. mode=.. sync=dirty-bitmap bitmap=bitmap0 bitmap-use-mode=re
