From 7fbcbd48d2898935369b443a489ea79d49fe19c4 Mon Sep 17 00:00:00 2001 From: Yonit Halperin Date: Tue, 21 Aug 2012 11:51:55 +0300 Subject: [PATCH] spice: notify spice server on vm start/stop Spice server needs to know about the vm state in order to prevent attempts to write to devices when they are stopped, mainly during the non-live stage of migration. Instead, spice will take care of restoring this writes, on the migration target side, after migration completes.
