+Subject: [PATCH] Fix video restarting sync issue
+
+There is a video start/stop sync issue inbetween ikvm server and
+ikvm manager because newClient and clientGone callback called
+by a different thread from libvncserver. To fix this issue, this
+commit moves the video.start() call from server to manager to
+unify video control thread.
+
+Tested:
+  Open KVM web page and reload the web page by pressing F5.
+  KVM page should be reloaded correctly.
