From ed65fd1a2750d24290354cc7ea49caec7c13e30b Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Fri, 16 Oct 2015 12:25:54 +0200 Subject: [PATCH] virtio-blk: switch off scsi-passthrough by default Devices that are compliant with virtio-1 do not support scsi passthrough any more (and it has not been a recommended setup anyway for quite some time). To avoid having to switch it off explicitly in newer qemus that turn on virtio-1 by default, let's switch the default to scsi=false for 2.5.
