Passthrough reading and recording (a.k.a., “burning”) are not supported by Xen. Currently, the only options for reading and recording optical discs (e.g., CDs, DVDs, BRDs) in Qubes are:
- Use a USB optical drive.
- Attach a SATA optical drive to a secondary SATA controller, then assign this secondary SATA controller to a VM.
- Use a SATA optical drive attached to dom0. (Caution: This option is potentially dangerous.)
To access an optical disc via USB follow the typical procedure for attaching a USB device, then check with the Qubes Devices widget to see what device in the target qube the USB optical drive was attached to. Typically this would be
sr0. For example, if
sys-usb has device
3-2 attached to the
sr0, you would mount it with
mount /dev/sr0 /mnt/removable. You could also write to a disc with
wodim -v dev=/dev/sr0 -eject /home/user/Qubes.iso.
