Re: [libvirt] [PATCH 4/9] qemu: Do not start with source for removable disks if tray is open

Are we trying to map the tray='open' to what the guest sees (in which case, we should reject it for non-cdrom guest views), what the host sees (even if the guest is viewing the storage as a non-cdrom IDE disk, but the host storage backing that disk is a cdrom), or both? I would argue that <target tray='open'/> should describe _only_ the guest's view, regardless of host state (if host is even tying a physical cdrom to the guest), and that if we _need_ the host state, that it should be an optional element in <source>.
