[Qemu-devel] [PATCH v6 for-2.7 07/28] migration: force QEMUFile to block


From: Daniel P. Berrange
Subject: [Qemu-devel] [PATCH v6 for-2.7 07/28] migration: force QEMUFile to blocking mode for outgoing migration
Date: Wed, 27 Apr 2016 11:04:57 +0100

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.
