From 12bd451fe0be83474910bb63b5874458141d4230 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 18 Jan 2012 14:40:46 +0000 Subject: qmp: add block_stream command Add the block_stream command, which starts copy backing file contents into the image file. Also add the BLOCK_JOB_COMPLETED QMP event which is emitted when image streaming completes. Later patches add control over the background copy speed, cancelation, and querying running streaming operations.
