Hello everyone,
I managed to get my bluray drive working in my VM without major flaws, thanks to these useful posts:

https://forum.proxmox.com/threads/a...nal-sata-dvd-burner-solved.47541/#post-224603

But when i start reading a disk over it, i get massive log spam on pve host, aswell as on guest os.
Those logs look like this:

Host log:
Code:
Jun 21 00:01:17 pve tgtd[32495]: tgtd: bs_sg_cmd_submit(228) failed to start cmd 0x0x559a67540bb0

Jun 21 00:01:17 pve tgtd[32495]: tgtd: bs_sg_cmd_submit(228) failed to start cmd 0x0x559a67540bb0
Jun 21 00:01:17 pve tgtd[32495]: tgtd: graceful_write(87) sg device 11 write failed, errno: 22

Guest log:
Code:

These messages appear around 10 times per second, sometimes more, sometimes less.
It doesn't matter what kind of disk im reading (CD/DVD/Bluray).
The disk is read without any visible/hearable errors in its content.


I tried googling those errors but i can't find any solution...

Does anyone around here know about this?

I seem to be having the same issue, if I wait until the VM is booted then insert a CD it works fine but the discID is mangled I assume that it is not passing through the raw device but I don't know how to pass it through correctly

I have the same issue when working with Bluray discs in my 4 DVD/Bluray readers/burners; however, working with DVD discs I do not get the log messages and they function as expected (though about 50% slower than when they operated directly under Windows 10 Pro). I don't mind the functional but slower for the DVD's, but it is frustrating not being able to get the Blurays functioning.
