Scenario:
A database server living in a virtual machine. (KVM-RHEV)http://pastebin.com/djj8q98j
Is there anything I can do to slow down memory writing at the database level in order to accomplish live migration?
Thank you for any ideas on this.

Wrong list. This is a pgAdmin specific list.
Though I guess a possibility would be to setup a connection pooler between your clients and Postgres and limit the number of concurrent connections to the database to a very small number. This would effectively serialize your operations, thereby reducing the activity on the VM.
Please don't follow up on this list. You can also try pgsql-es-ayuda@postgresql.org which is a general postgresql list in Spanish.
Cheers.
