From daa91de28dd011a39b80d76da96c432273fb5bf2 Mon Sep 17 00:00:00 2001 From: Glauber Costa Date: Wed, 20 May 2009 18:26:58 -0400 Subject: [PATCH] allow changing the speed of a running migration This patch allow us to call migrate_set_speed on running migrations. This should allow mgmt tools to increase the allocated bandwidth of a running migration if there is no progress, and they really want the migration to succeed.
