Hello - thankyou for your interest.

One area to look at might be the parameters to the live migration
looping.  As part of the migration v2 rework I did in the 4.6 dev
period, I left all of that alone, and it is in a working but poor state.

In the past, there have been several research investigations into
improving the live migration algorithm, such as tracking the rate of
dirtying of memory, or attempting to resume the domain on the far side
and fault the final memory across.

If you are interested in perusing this, start with reading
docs/features/migration.pandoc in the Xen tree.
