From 7f9744812291853425b614f68668f48d49882a1f Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Wed, 2 Jun 2010 11:40:54 +0300 Subject: [PATCH] virtio-net: stop vhost backend on vmstop vhost net currently keeps running after vmstop, which causes trouble as qemy does not check for dirty pages anymore. The fix is to simply keep vm and vhost running/stopped status in sync. Tested-by: David L Stevens Signed-off-by: Michael S.
