From dc33bb341122623105573d47fa6d71a0ba5ff15c Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 26 May 2010 10:44:44 +0200 Subject: [PATCH] drive: allow rerror, werror and readonly for if=none When creating guest disks the qdev way using ... -drive if=none,id=$name,args -device $driver,drive=$name it is not possible to specify rerror, werror and readonly arguments for drive as drive_init allows/blocks them based on the interface (if=) specified and none isn't white-listed there.
