[Qemu-devel] [PATCH] fixup! virtio-blk: fail get_features when both scsi

From: Paolo Bonzini
Subject: [Qemu-devel] [PATCH] fixup! virtio-blk: fail get_features when both scsi and 1.0 were set
Date: Mon, 27 Jul 2015 13:41:32 +0200

Tweak the error message so that it does not mention SCSI passthrough.  That
can be confusing because you can have scsi=on even for file-backed image,
which obviously do not support SCSI passthrough at the block layer level.
