[Qemu-devel] [PATCH 0/1] migration: calculate expected_downtime consider

Subject: [Qemu-devel] [PATCH 0/1] migration: calculate expected_downtime considering redirtied ram
Date: Tue, 22 Jan 2019 20:35:42 +0530

From: Balamuruhan S <address@hidden>

Based on the discussion with Dave and David Gibson earlier with respect
to expected_downtime calculation, 


got suggestions that the calculation is of not accurate and we need to
consider the ram that gets redirtied during the time when we would have
actually transferred ram in the current iteration.

so I have came up with a calculation by considering the ram that could
get redirtied during the current iteration at the time we would have
transferred the remaining ram in current iteration. By this way,
the total ram to be transferred will be remaining ram + redirtied ram
and dividing with bandwidth would yield us better expected_downtime

Please help to review and suggest about this approach.
