You are using the option --live to migrate, aren't you?

Yes, I am. :)
Even if I weren't, it would make sense to expect a lower downtime (or the same downtime) by reducing the domU memory. But it takes longer if I reduce the domU's memory.

Would you happen to have any ideas on why it behaves like that?
