September 30, 201411 yr I was trying to get access to my Blu-Ray drive from a Windows 7 VM under XEN. Here is the initial threat: http://lime-technology.com/forum/index.php?topic=32344.0 Since jonp gave the advise to give KVM a try ("....with Xen, I can't help much because I'm not touching it much anymore except making sure it "works" from beta to beta. With KVM though, this is very simple to do using either webvirtmgr or virt-manager.") I migrated my two VMs to KVM and I do see the following messages in syslog (I used VMM on Ubuntu on another machine to passthrough my Adaptec 1220SA that has just the Blu-Ray drive attached): Sep 30 09:45:16 Tower kernel: sata_sil24 0000:03:00.0: enabling device (0400 -> 0403) Sep 30 09:45:16 Tower kernel: scsi10 : sata_sil24 Sep 30 09:45:16 Tower kernel: scsi11 : sata_sil24 Sep 30 09:45:16 Tower kernel: ata17: SATA max UDMA/100 host m128@0xdfa84000 port 0xdfa80000 irq 16 Sep 30 09:45:16 Tower kernel: ata18: SATA max UDMA/100 host m128@0xdfa84000 port 0xdfa82000 irq 16 Sep 30 09:45:18 Tower php: Stopping libvirtd...

October 3, 201411 yr Can you show me your XML for this? You can get to it under /etc/libvirt/qemu/domainname.xml if you used a virtualization manager to build it.
October 3, 201411 yr Author Sure jonp, here you are. It would be great to avoid passing through the controller but only the Blu-ray drive.
October 3, 201411 yr Sure jonp, here you are. It would be great to avoid passing through the controller but only the Blu-ray drive. I got you covered. Here's what I want you to do: Go to command line and type: lsscsi You should get a list like this: [0:0:0:0] disk Corsair Flash Voyager 1100 /dev/sda [1:0:0:0] disk ATA ST32000542AS CC34 /dev/sdb [2:0:0:0] disk ATA ST4000DM000-1F21 CC52 /dev/sdc [3:0:0:0] disk ATA WDC WD20EARS-00M AB50 /dev/sdd [6:0:0:0] disk ATA PLEXTOR PX-128M3 1.01 /dev/sde [7:0:0:0] disk ATA ST4000DM000-1F21 CC52 /dev/sdf [8:0:0:0] disk ATA WDC WD20EARS-00M AB50 /dev/sdg [9:0:0:0] disk ATA WDC WD40EZRX-00S 0A80 /dev/sdh [10:0:0:0] disk ATA ST4000DM000-1F21 CC52 /dev/sdi [12:0:0:0] cd/dvd HL-DT-ST BD-RE WH14NS40 1.01 /dev/sr0 Ok, now look for something that looks like the bolded red part above. Then you need to transpose the red part into this: <controller type='scsi' index='0' model='virtio-scsi'/> <hostdev mode='subsystem' type='scsi'> <source> <adapter name='scsi_host12'/> <address type='scsi' bus='0' target='0' unit='0'/> </source> <readonly/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </hostdev> Put all of the above somewhere in your XML between <devices> and </devices>. Then use webvirtmgr and create an instance from XML and copy / paste the entire XML content into there. Should work like a charm and no PCI device pass through necessary. Your complete win7.xml file should look something like this (new part bolded black and red part for text to replace with values from your system): <!-- WARNING: THIS IS AN AUTO-GENERATED FILE.

I was getting this error code via WebVirtManager: internal error: Failed to open /sys/bus/scsi/devices/12:0:0:0/scsi_generic I tried it again 2 times and lsscsi was showing an increment of 2, that means [14:0:0:0] cd/dvd HL-DT-ST BD-RE BH10LS30 1.02 /dev/sr0 after the second and [16:0:0:0] cd/dvd HL-DT-ST BD-RE BH10LS30 1.02 /dev/sr0 after the third try. I have attached the xml and the syslog.
October 4, 201411 yr The plot thickens!! Try this. Save the XML I gave you somewhere on the server, login via console and type "virsh create win7.xml" (as opposed to copy and paste in web virt mgr). Just want to see if this is an issue with how libvirt imports the domain.
October 4, 201411 yr Oh and when you say XML editor, do you mean you are trying to edit the existing VM? If so, try creatinh a new "instance" from XML and pasting it in that way. Editing existing XML from web virt mgr and creating a new instance are a little different in their operation...
October 4, 201411 yr Author lsscsi was showing: [20:0:0:0] cd/dvd HL-DT-ST BD-RE BH10LS30 1.02 /dev/sr0. Here are the steps that I took: generated another UUID copied the whole win7 folder - incl. both files - xml and qcow2 into a new directory (windows7) virsh create windows7.xml Error message: error: Failed to create domain from windows7.xml error: internal error: Failed to open /sys/bus/scsi/devices/20:0:0:0/scsi_generic lsscsi is now showing: [22:0:0:0] cd/dvd HL-DT-ST BD-RE BH10LS30 1.02 /dev/sr0
October 4, 201411 yr Wtf. This is really weird. I have a friend of mine who has this working no problem, but I need to take another look at his setup. We will get to the bottom of this.
October 5, 201411 yr Author Thanks jonp, I'm going to try the same procedure tomorrow on my test server. Maybe better luck there. [EDIT] Sorry to say but it's working on my backup server either: lsscsi: [0:0:0:0] disk Flash Drive SM_USB20 1100 /dev/sda [1:0:1:0] cd/dvd HL-DT-ST DVDRAM GH24NS95 RN01 /dev/sr0 [3:0:0:0] disk ATA KINGSTON SV100S2 225a /dev/sdb [4:0:0:0] disk ATA WDC WD20EARS-00M AB51 /dev/sdc [5:0:0:0] disk ATA WDC WD10EAVS-00D 1A01 /dev/sdd [6:0:0:0] disk ATA Hitachi HDS72101 A3EA /dev/sde [7:0:0:0] disk ATA ST31000340AS SD15 /dev/sdf I deleted the instance via WebVirtManager and redefined it via "New Instance".

October 5, 201411 yr OK, let me make sure I'm hearing you right. You're telling me this is happening on two separate systems the same way? Different hardware too (e.g. different DVD drive)? OK, something is definitely out of whack here.
October 5, 201411 yr Author Exactly - please see my signature and you can see what HW/SW environment is involved. [EDIT:] I have just discovered, that I haven't answered all of your questions: 1.) [2:0:0:0] cd/dvd HL-DT-ST BD-RE BH10LS30 1.02 /dev/sr0 (this is the Blu-Ray Drive installed in my production server) 2.) [1:0:1:0] cd/dvd HL-DT-ST DVDRAM GH24NS95 RN01 /dev/sr0 is a simple DVD Drive installed in my test/backup server. Btw, have you seen that lsscsi was again showing a different address?
October 30, 201411 yr Author I was giving the DVD Drive passthrough another try....strange enough, it was working this time - at least partially. The Red Hat VirtIO SCSI pass-through controller entry in Windows device overview is new. Since then the DVD drive is shown under DVD/CD-ROM-Drives. However, I don't have proper access to it. When I'm loading a CD I see the tracks but it isn't playing any. Instead Windows is showing an I/O Error.

December 16, 201411 yr I am not having any luck with this. Is it because I am using the qemu:arg template? My template will not save when I click "Add XML".

December 16, 201411 yr So I got it working by using the following code, DVD drive shows up in windows, now to test and see if it will play something. <hostdev mode='subsystem' type='scsi' managed='no'> <source> <adapter name='scsi_host5'/> <address bus='0' target='0' unit='0'/> </source> <readonly/> <alias name='hostdev1'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </hostdev>
December 16, 201411 yr Author archedraft, if you are using Windows, please don't miss to install the virtio pass-through controller driver (see screenshot). I do see the drive in explorer, device manager, etc. but still no luck accessing the drive e.g. with MakeMKV: Fehler 'SCSI-Fehler - ILLEGAL REQUEST:INVALID FIELD IN CDB' trat auf während der Übertragung des SCSI-Befehls 460200010..00100 zu Laufwerk 'SPTI:\Device\CdRom0' Also VLD doesn't play any DVD
December 16, 201411 yr QEMU 2.2 (recently released) has improved the virtio-scsi passthrough so that may solve these issues. This will be included in one of the future beta versions.
December 17, 201411 yr Thought I would respond and say that my dvd drive also does not function properly. It loads the cd fine but once you try and do anything with the cd it freaks out. Hopefully the new QEMU fixes the issues, it's not critical to have the dvd drive but I would like to have the option.
February 17, 201511 yr Author As far as I can see, we have QEMU 2.2 implemented in Beta13. Is there anything that I missed, as I can't see that the issue has disappeared. Any advise? Thanks a lot.
February 19, 201511 yr As far as I can see, we have QEMU 2.2 implemented in Beta13. Is there anything that I missed, as I can't see that the issue has disappeared. Any advise? Thanks a lot. Might have some updated things for you to try after we get to beta14. Laser focused on getting that release out right now.
March 4, 201511 yr You can try the rawio='yes' attribute in the hostdev tag (and possibly managed='no'): <devices> ... <controller type='scsi' index='0' model='virtio-scsi'/> <hostdev mode='subsystem' type='scsi' managed='no' rawio='yes'> <source> <adapter name='scsi_host12'/> <address type='scsi' bus='0' target='0' unit='0'/> </source> <readonly/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </hostdev> ... </devices>
March 6, 201511 yr Author Thanks eschultz, I added the rawio item, but no changes. I see the drive, directories and files but as soon as I'm starting e.g. MakeMKV it is showing the same error: Fehler 'SCSI-Fehler - ILLEGAL REQUEST:INVALID FIELD IN CDB' trat auf während der Übertragung des SCSI-Befehls 460200010..00100 zu Laufwerk 'SPTI:\Device\CdRom0' Same result on both servers. No errors in unRAID log. Can I help investigating in any way? Please advise. Thanks a lot.
July 2, 201511 yr Any update on this? Were you able to get it working? I'd like to move from ESXi to unRAID for my Windows VM that has a BD-ROM attached.
July 2, 201511 yr Any update on this? Were you able to get it working? I'd like to move from ESXi to unRAID for my Windows VM that has a BD-ROM attached. It's working for me, but only with certain software and reduced speed compared to not virtualized windows. Dvdfab and anydvd HD works. Makemkv does not work. It can scan the disc and find tracks, but gets stuck analysing the segments and never starts copying to disk. Power DVD worked, but lagged a lot. Hopefully I can get a USB 3 to sata adapter to work when passing through the USB 3 controller.
