[Qemu-devel] [PATCH 0/4] migration: autoconverge counter fixes

Posted by Felipe Franciosi 73 weeks ago
As discussed in the ML [1], there are some issues around the way ram.c accounts
for transferred data and dirty pages for the auto convergence calculations. The
patches in these series fix that by:

- Keeping bytes_xfer_prev zeroed until it's used
- Ensure bytes_xfer_* counters are accounted for the same period as
  dirty_pages_* counters
- Start throttling in a consistent manner

[1] http://lists.nongnu.org/archive/html/qemu-devel/2017-05/msg05524.html

Felipe Franciosi (4):
  migration: keep bytes_xfer_prev init'd to zero
  migration: set dirty_pages_rate before autoconverge logic
  migration: set bytes_xfer_* outside of autoconverge logic
  migration: use dirty_rate_high_cnt more aggressively
