From c83c66c3b58893a4dc056e272822beb88fe9ec7f Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 25 Apr 2012 16:51:03 +0100 Subject: block: add 'speed' optional parameter to block-stream Allow streaming operations to be started with an initial speed limit. This eliminates the window of time between starting streaming and issuing block-job-set-speed. Users should use the new optional 'speed' parameter instead so that speed limits are in effect immediately when the job starts.
