Comment 9 for bug 784937

Just as some additional background information while there is upstream discussion going on. I am not sure how it will end as yesterday responses rather made hope for getting things back and today there is others rather wanting to preserve the current status.

The main argument is HVM as you can have the IDE disks provided as hd* devices on an emulated controller and at the same time via xvd*. So they want to preserve the first 4 device names for that.
