CD ROMs in WIndows Qube...won't show up

Qubes 4.2

Windows 7 SP1

QWT is installed

I cannot get a CD ROM to “show up” in the Windows 7 qube. I’ve done the attachment through qui-devices, but I never see the CD ROM as a disk in WIndows, and it doesn’t show up in Windows’ disk management at all.

Is this related somehow to the fact that read only block devices (e.g., ones created by losetup in another qube) also won’t show up in Windows 7 qubes?

QWT does not install Xen PV disk drivers by default which might result in that behaviour.

Please refer to Qubes Windows Tools (QWT) documentation under this section:

Note: Xen PV disk drivers are not installed by default.
