From 9e4d2b98ee98f4cee50d671e500eceeefa751ee0 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Wed, 27 Apr 2016 11:04:57 +0100 Subject: migration: force QEMUFile to blocking mode for outgoing migration Instead of relying on the default QEMUFile I/O blocking flag state, explicitly turn on blocking I/O for outgoing migration since it takes place in a background thread.
