[Qemu-devel] [PATCH 02/14] spice: notify spice server on vm start/stop |
Date: |
Thu, 6 Sep 2012 09:21:28 +0200 |
From: Yonit Halperin <address@hidden>
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.
