From 1f56e32a7f4b3a60bbabc499a63f3b858f472306 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 16 May 2011 15:04:52 +0200 Subject: ide: Split qdev "ide-drive" into "ide-hd" and "ide-cd" An "ide-drive" is either a hard disk or a CD-ROM, depending on the associated BlockDriverState's type hint. Unclean; disk vs. CD belongs to the guest part, not the host part. Have separate qdevs "ide-hd" and "ide-cd" to model disk vs. CD in the guest part. Keep ide-drive for backward compatibility. "ide-disk" would perhaps be a nicer name than "ide-hd", but there's already "scsi-disk", which is like "ide-drive", and will be likewise split in the next commit. {ide,scsi}-{hd,cd} is the best consistent set of names I could find within the backward compatibility straightjacket.
