Thank you. I tried this first but passing through the HBA controller made Proxmox crash. Didn't work.
a simple way to passthrough an internal SATA DVD burner [solved]
- Thread starter maxprox

There the "separate controller". Of course everything crashs if you passthrough a used device.
Very vague statement...? We tried to separate it as much as we could. Moved it to different IOMMU groups but it just doesn't work on that machine.
So, this kind of works for me. I followed along with the posts in this thread and i have a proxmox 8.1.10 box with 3 optical drives in it shared via iSCSI. all miss-matched.
- LG WH16NS60 (UHD running LibreDrive firmware)
- LG WH14NS40 (UHD running LibreDrive firmware)
- ASUS BW-16D1X-U but really is a Pioneer pulled out of an external enclosure (Blu-ray running stock firmware)
Never-mind, it looks like it was the disks i was using. I used a different set of disks and while it was very slow it did not stall out.
Just to throw my $.02 here... I really want to use MakeMKV with a VM but I wasn't prepared to go down the wild iSCSI hack, and my mobo has a 2230 E-key connector, which there are JMicron SATA controllers to fit into this slot - which is just a PCIe slot. So I figured Passthrough had to work to a Windows VM. I bought the part and installed it and it worked for one disc but the next disc I tried it just wouldn't read. =( I also experienced some terrible mouse stuttering and overall unhappy VM behaviors (but no crashes, but I did have to Stop the VM a couple times to recover). I tried installing the JMicron SATA driver (Win10 listed only, but 11 took it) but that seemed to make things worse. I really had hopes for this solution. I don't need to do this all the time but I wanted the option in Proxmox. I may go down the iSCSI route but I'll probably just put the drive back in my bare metal and maybe try the E-Key passthrough at a later Proxmox version time.
A bit old thread, but with little AI help, I found a simpler way to passthrough an internal SATA DVD burner :
Add this line at the very bottom of /etc/pve/qemu-server/[VM-ID].conf :
Replace /dev/sgX with your actual generic node (e.g., /dev/sg2). Find it using lsscsi -g
Also ensure you have a SCSI Controller added in the GUI ( VirtIO SCSI or VirtIO SCSI single), even if no disks are attached to it. This ensures the necessary SCSI bus exists for the args line to hook into.
Add this line at the very bottom of /etc/pve/qemu-server/[VM-ID].conf :
Code:
args: -device scsi-generic,drive=dr1 -drive file=/dev/sgX,if=none,id=dr1Replace /dev/sgX with your actual generic node (e.g., /dev/sg2). Find it using lsscsi -g
Code:
root@proxmox:~# lsscsi -g
[0:0:0:0] disk ATA SED2FIV-M SATA S 7A /dev/sda /dev/sg0
[1:0:0:0] disk ATA WDC WD1003FZEX-0 1A01 /dev/sdb /dev/sg1
[2:0:0:0] cd/dvd HL-DT-ST BD-RE BH10LS30 1.00 /dev/sr0 /dev/sg2
[3:0:0:0] disk ATA WDC WD1003FZEX-0 1A01 /dev/sdc /dev/sg3
And you can read/RIP audio CDs, burn DVDs and play movie DVDs from within the VM? Can you please try those things and let us know.
I already successfully wrote an iso file to blank DVD and was able to read it after that. On monday I can try to rip an audio cd and play DVD. It should work I think wthout problems, because the K3b software on the guest VM detects the device as writer and can use it. I'll post the results.
Update : I can confirm, that read/RIP audio CDs, burn DVDs and play movie DVDs from within the VM works. Regards!
