Before we take the hammer to it, could you try reducing it's initial
bandwidth, the code that says:
/*
* Set the initial parameters so that the migration could not converge
* without throttling.
*/
migrate_set_parameter_int(from, "downtime-limit", 1);
migrate_set_parameter_int(from, "max-bandwidth", 100000000); /* ~100Mb/s */
knock a couple of 0's off that and see if it's happy.
