[Qemu-devel] [PATCH 2/2] allow changing the speed of a running migration |
Date: |

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.
