From 52c9cf1ac3d315995e9a65b900bc25e1d8a538b3 Mon Sep 17 00:00:00 2001 From: "Michael S. Tsirkin" Date: Wed, 15 Oct 2014 10:22:32 +1030 Subject: [PATCH] virtio_scsi: enable VQs early on restore virtio spec requires drivers to set DRIVER_OK before using VQs. This is set automatically after restore returns, virtio scsi violated this rule on restore by kicking event vq within restore. To fix, call virtio_device_ready before using event queue.
