From b6a4805b55b409134dc712677fdc4f6a8795e965 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 3 Aug 2010 16:57:02 +0200 Subject: virtio-blk: Fix migration of queued requests in_sg[].iovec and out_sg[].ioved are pointer to (source) host memory and therefore invalid after migration. When loading the device state we must create a new mapping on the destination host.
