Виртуальный cd rom для linux

Виртуальный CD/DVD-RW привод

Есть ли под linux программа для эмуляции CD/DVD-RW привода с возможностью записи.
Т.е. я создаю на диске пустой файл, который в роли виртуального компакт-диска как бы вставляю в виртуальный CD/DVD-RW привод, пишу в этот виртуальный привод, а на самом деле информация сбрасывается в файл (но не просто iso-файл, а полный побайтовый слепок, ибо в iso, например, не запихнуть AudioCD).
Под Windows у меня была софтина VirtualCD, полностью меня устраивавшая. Под linux уже пол дня не могу найти. Пробовал cdemu — вроде в него нельзя писать.
На вопросы, зачем мне это надо, отвечать принципиально не буду. Есть определённая проблема, прошу подсказать путь её решения.

А /dev/loop разве ro?

Да причем штатными средствами.

man mount, man dd, man mkfs

дай угадаю. пытаешься скормить диск игрушке под вайн?
Так надо в нём самом для опред. приложения просто назначить путь до сидирома.

З.Ы. А штатное монтирование iso ещё никто не отменял.

пока на линуксе не появится игрушек, не будет и хороших программ (типа VirtualCD и DaemonTools)

1) ТСу надо именно возможность записи

2) штатное монтирование iso — полная фигня. Даже бетка первого старфорса видела неиллюзорную разницу между настоящим диском и изошкой. Туда надо методы изощреннее — эмулировать IDE (чтобы как минимум обойти блэклист), плюс плотность записи и временные задержки, плюс эксклюзивный доступ к девайсу без блокировки I/O — и много еще чего.

Bugfix release — CDEmu daemon & libMirage 3.0.1!

July 25th, 2014

• added missing installation rules for GBI and XMD MIME types (Bug #81)

• fixed CD-R and DVD+R SAO recording with cdrecord from cdrtools (Bug #80)

New release! CDEmu 3.0.0!

June 29th, 2014

This is the first release of new 3.0.0 series, which marks the addition of support for image writing across whole CDEmu suite. The file access and filter stream layer in libMirage were revised to allow implementation of filters for both reading and writing, and an infrastructure for implementing image writers was added, along with reference implementations for ISO and TOC writers. CDEmu daemon now has experimental emulation of CD-R and DVD+R disc recording, and daemon/client protocol was extended to allow transmission of image writer parameters descriptions from daemon to client and parameters’ values back from client to daemon. Both cdemu-client and gCDEmu client thus now allow user to create a «blank» disc on CDEmu device and write to it using CD/DVD burning software. And as a side effect, the image analyzer application also gained support for image conversion.

In other news, image analyzer has been converted into a fully-fledged gtk3 application, and gCDEmu now prefers appindicator mode over gtk trayicon mode whenever AppIndicator(3) is available, as it offers better support for new systray protocol than gtk3. Client translations have been brought up to date for Norwegian and Slovenian language, and Swedish translation was updated for gCDEmu and added for cdemu-client (courtesy of Anders Jonsson).

Several reported bugs have also been fixed, while hopefully none were introduced, and most of the code has been through rather extensive clean-up — for a complete list of changes, consult our repository’s change log. As always, the source packages can be obtained from project site; if you encounter any issues, report them via appropriate tracker, and/or send your comments/concerns/suggestions to our mailing list.

Create Virtual CD And DVD Drives Using CDEmu On Linux

CDEmu is a software suite used to emulate optical CD-ROM and DVD-ROM drives on Unix-like systems. Using CDEmu, we can easily mount various disk image formats, such as BIN, CUE, ISO, IMG, MDF and NRG etc., in Linux without having to write them in physical media. This can be helpful for playing certain types of Games which runs only from the optical drive. In this brief tutorial, we are going to see how to install CDEmu and create virtual CD ad DVD drives using CDEmu on Linux from command line as well as graphical mode.

CDEmu consists of the following components:

• VHBA (Virtual HBA) — A kernel module implementing a virtual drive-controller.
• libMirage — A software library for interpreting optical disc images.
• CDEmu daemon — A userspace daemon that receives SCSI commands from kernel module and processes them, passing the requested data back to the kernel.
• CDEmu client — A command-line client for controlling CDEmu daemon.
• gCDEmu — A graphical interface for CDEmu client.
• Image Analyzer — A Gtk+ application that displays tree structure of disc image created by libMirage.

Install CDEmu on Linux

CDEmu is packaged for many popular Linux platforms.

On Arch Linux and its variants, make sure you have enabled [Community] repository and install CDEmu client using command:

On Ubuntu, it can be installed using PPA like below.

Create Virtual CD And DVD Drives Using CDemu On Linux

Here are a few basic examples to mount, unmount and list images using cdemu command.

Load images in virtual devices

To load an ISO image in the first virtual drive, run:

Now Open your File manager to verify if the image is loaded.

As you see in the above screenshot, I have mounted Alpine ISO image using CDEmu client.

To load multiple images in the first drive, simply mention its path with space-separated like below.

View images in virtual devices

To view the list of loaded images, run:

As you see, I have loaded alpine ISO image in the first drive.

Unload images from virtual devices

To unload the first drive i.e unmount the loaded images from the first drive, run:

This command will unload all images from the first device. You can verify if the images are unloaded using «cdemu status» command.

Create new virtual device

By default, CDEmu has one virtual drive. You can of course create more drives if you like.

To add a new device, for example device 1, the command would be:

You will see an output like below.

To verify if the new device is created, run:

As you see, I have two virtual devices, 0 and 1.

You can create as many devices as you want.

To load the ISO images to the second drive, run:

Remove virtual drives

To remove a virtual drive, run:

This command will remove the last virtual device. Please note that this command will unmount all loaded images in the last drive automatically and then delete the drive itself.

This is just enough to get started with cdemu.

Of course, It has more options. You can refer them from the help section.

gCDEmu — A GTK client for CDEmu

If you’re not comfortable with command line, there are also a few graphical clients available for CDEmu. One such client is gCDEmu.

gCDEmu is a GTK application for controlling CDEmu daemon that allows you to load, unload and display virtual device status via a simple graphical window.

gCDEmu is available in the default repositories of some Linux distributions.

On Arch Linux and its variants, you can install gCDEmu from AUR using any AUR helpers, for example Yay.

On Debian 10, 9, 8:

On Ubuntu, you need to add the official PPA for cdemu as shown in the «Install cdemu on Linux» section above an then install gCDEmu using command:

Once installed, launch gCDEmu either from Dash or Menu. It will be probably found under Menu -> System Settings -> gCDemu.

After launching, you will notice gCDEmu icon in the task bar. Click the gCDemu icon and select Device #00 or Device #01 to mount your images.

Click «Load» and browse the ISO to load:

The ISO will be mounted now and you can see it in the File manager.

After done with the ISO image, simply press the «Unload» button in the gCDemu window or eject from the file manager.

You can create many virtual devices and load the images in any virtual devices of your choice. To create a new device, click on the gCDEmu icon in the task bar and select «New device» option.
