Subject: [Qemu-commits] [COMMIT daa91de] allow changing the speed of a running migration
Date: Fri, 22 May 2009 15:52:46 -0000

From: Glauber Costa <address@hidden>

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.
