[Qemu-devel] [PATCH v2 0/3] fix bitmaps migration through shared storage

Posted by Vladimir Sementsov-Ogievskiy 6 years, 4 months ago

Hi all.

This fixes bitmaps migration through shared storage. Look at 02 for
details.

The bug introduced in 2.10 with the whole qcow2 bitmaps feature, so
qemu-stable in CC. However I doubt that someone really suffered from this.

v2:
   John, thank you for reviewing v1.
   changes:
    add John's r-bs, change s/timeout=10/timeout=10.0/ in last patch
    and drop old 03 patch, related to this timeout fix.

Vladimir Sementsov-Ogievskiy (3):
  qcow2-bitmap: add qcow2_reopen_bitmaps_rw_hint()
  qcow2: handle reopening bitmaps on bdrv_invalidate_cache
  iotests: add dirty bitmap migration test

Should qemu-stable be here?
