This patch adds sync modes on top of the work that Stefan Hajnoczi has done.
These patches apply on kevin/block with
'[PATCH] block: add drive_backup HMP command' also applied.
Hopefully all is in order as this is my first QEMU patch. Many thanks to
Stephan and Fam Zheng for their help.
V2:
- No longer poll, instead use qemu_coroutine_yield().
- Use bdrv_co_is_allocated().
- Much better SYNC_MODE_NONE test.
V3:
- A few style fixes.
- Better commit message explaining how TOP and NONE operate.
- Verified using checkpatch.pl.
V4:
- Add patch to use the source as a backing hd during backup.
- Add patch to default sync mode none to qcow2.
Ian Main (4):
Implement sync modes for drive-backup.
Add tests for sync modes 'TOP' and 'NONE'
Add backing drive while performing backup.
Change default to qcow2 for sync mode none.
