How to burn CD/DVD at Qubes OS R3 (rc1) ?

[Vladimir Shipovalov]

I installed Brasero to "untrusted" VM and attached CDROM (dom0:sr1 block device) to this VM through Qubes VM Manager interface. However, Brasero cannot detect my CDROM. Please tell, what should I do to make it working? (and is it possible at all, to burn CD/DVD disks under Qubes OS)

P.S. Hardware of CDROM is OK - and, if I insert a disk with data, at Dom0 I can mount CDROM to directory and browse these files

Vladimir Shipovalov:

This has come up on the list a few times. You cannot attach a block
device like that and burn a CD/DVD. Your only options are to burn from
Dom0, to attach the whole SATA controller with the CD/DVD drive to the
VM, or to get an external drive and attach the appropriate USB
controller to the VM.

Thank you very much for replies! By the way, I also tried USB CDROM recently, but results are the same:
it also appears in system as dom0:srX (X-number) and is not detected by DVD burning apps at domains.
Maybe the only working option here would be installing Brasero to dom0, despite a security risk...

You've to assign the appropriate USB controller [0] to your burning-vm
(you might use your usbvm) before starting it.
Then add user to group cdrom in this burning-vm (`sudo useradd -G
cdrom user` or `sudo vigr (-s)`).
