CDEmu

What CDEmu is

CDEmu is a free Linux suite for emulating optical drives and discs, including CD-ROM and DVD-ROM media. Its kernel module creates a virtual SCSI host adapter that connects the Linux kernel with a userspace daemon. The libMirage library provides access to optical disc image formats such as MDS, MDX, CCD, CUE, BIN, TOC, CDI, ISO, NRG, UDF, DMG, CSO, GZ, DAA and ISZ. Emulated media can be mounted in Linux, and automounting is available. The project also describes experimental CD-R and DVD+R recording emulation for writing blank virtual discs with disc-burning software. Users can manage devices, check status and set debug masks through command-line or GTK clients. The daemon exposes methods over D-BUS and can use either the session bus or system bus. The project is licensed under GNU GPL version 2 or later and lists official source tarballs and distribution packages. The maintainers say third-party distribution packages are not verified or formally supported. System-bus use requires special permissions, while session-bus use requires read and write access to the VHBA control device.
