From 449e3578107799817a81249b189f6f82aa9e787d Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Wed, 25 Nov 2015 13:39:57 +0200 Subject: Revert "vhost: send SET_VRING_ENABLE at start/stop" This reverts commit 3a12f32229a046f4d4ab0a3a52fb01d2d5a1ab76. In case of live migration several queues can be enabled and not only the first one. So informing backend that only the first queue is enabled is wrong.
