When we are copying storage we should also preserve the block dirty
bitmaps. This series implements their migration.
For standard migration with shared storage we let qemu flush the bitmaps
to disk and reload them on destination. There is possibility to migrate
them using the migration stream too but it's not implemented in this
series.
v2:
Patches from v1:
- patches 4-7 from v1 were pushed already
- patch 8 from v1 was dropped
This version:
- patch 1 was updated to capture the latest capabilities
- patch 4 is new, replaces patch 8 from v1
- all other patches apply review feedback from Jirka
- patch 14 has one additional change (thus I didn't carry Jirka's R-b):
The migration of bitmaps is enabled based on
QEMU_CAPS_MIGRATION_PARAM_BLOCK_BITMAP_MAPPING instead of
QEMU_CAPS_INCREMENTAL_BACKUP.
Peter Krempa (15):
qemucapabilitiesdata: Update test data for qemu-6.0 on x86_64

query-named-block-nodes
qemu: migration: Create qcow2 v3 images for
VIR_MIGRATE_NON_SHARED_DISK
qemu: monitor: Introduce qemuMonitorBitmapRemove
qemu: blockjob: Use qemuMonitorBitmapRemove for single bitmap removal
qemu: migration_params: Add infrastructure for 'dirty-bitmaps'
migration feature
qemu: migration_cookie: Add XML handling for setting up bitmap
migration
qemu: migration_cookie: Add helpers for transforming the cookie into
migration params
qemu: domain: Store list of temporary bitmaps for migration in status
XML
tests: qemustatusxml2xml: Add status XML from migration with bitmaps

New subject: [PATCH v2 02/15] qemu: capabilities: Introduce QEMU_CAPS_MIGRATION_PARAM_BLOCK_BITMAP_MAPPING
The capability represents qemu's ability to setup mappings for migrating
block dirty bitmaps and is based on presence of the 'transform' property
of the 'block-bitmap-mapping' property of 'migrate-set-parameters' QMP
command.

Such images don't support stuff like dirty bitmaps. Note that the
synthetic test for detecting bitmaps is used as an example to prevent
adding additional test cases.

And how about creating v3 only when the source offered bitmaps for
migration? Although automatic creation of disk images during migration
has always been magic and anyone caring about the exact image format on
the destination needs to precreate the images manually.
So I guess this should good enough.

New subject: [PATCH v2 05/15] qemu: monitor: Introduce qemuMonitorBitmapRemove
The non-transaction wrapper is useful for code paths which want to
delete individual bitmaps or for cleanup after a failed job where we
want to attempt to delete every bitmap individually to prevent a failure
from cleaning up the rest.

New subject: [PATCH v2 09/15] qemu: migration_cookie: Add helpers for transforming the cookie into migration params
'qemuMigrationCookieBlockDirtyBitmapsMatchDisks' maps the bitmaps from
the migration cookie to actual disk objects definition pointers.
'qemuMigrationCookieBlockDirtyBitmapsToParams' converts the bitmap
definitions from the migration cookie into parameters for the
'block-bitmap-mapping' migration parameter.

New subject: [PATCH v2 13/15] qemu: migration: Clean up temporary bitmaps when cancelling a migration
In case when the block migration job required temporary bitmaps for
merging the appropriate checkpoints we need to clean them up when
cancelling the job. On success we don't need to do that though as the
bitmaps are just temporary thus are not written to disk.

Preserve block dirty bitmaps after migration with
QEMU_MONITOR_MIGRATE_NON_SHARED_(DISK|INC).
This patch implements functions which offer the bitmaps to the
destination, check for eligibility on destination and then configure
source for the migration.

New subject: [PATCH v2 14/15] qemu: migration: Migrate block dirty bitmaps corresponding to checkpoints
On Fri, Feb 19, 2021 at 12:58:26 +0100, Peter Krempa wrote:
Preserve block dirty bitmaps after migration with
QEMU_MONITOR_MIGRATE_NON_SHARED_(DISK|INC).
This patch implements functions which offer the bitmaps to the
destination, check for eligibility on destination and then configure
source for the migration.

New subject: [PATCH v2 15/15] qemu: capabilities: Enable QEMU_CAPS_INCREMENTAL_BACKUP
For incremental backup we need QEMU_CAPS_BLOCKDEV,
QEMU_CAPS_BLOCKDEV_REOPEN, QEMU_CAPS_MIGRATION_PARAM_BLOCK_BITMAP_MAPPING.
