From b8193adbda922659ba290fd9fb6ee053ee191d70 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Mon, 7 Sep 2009 21:20:15 +0300 Subject: [PATCH] qemu: init all queues to NO_VECTOR value initialize vectors for all vqs to VIRTIO_NO_VECTOR rather than 0 which is a valid vector. This fixes migration which happened before driver was loaded. Signed-off-by: Michael S.
