Passthrough 2x DVD drives


Recommended Posts

Hi all,

 

Trying to pass these two drives through to my VM. 

 

[2:0:0:0] cd/dvd  TSSTcorp CDDVDW SH-S223C  SB05  /dev/sr0

[6:0:0:0] cd/dvd  TSSTcorp CDDVDW SH-S223B  SB01  /dev/sr1 

 

I see some threads where people have used the code below to get 1 drive going. Can anyone assist me by telling me where I need to copy this to and also how I edit it for two drives? I assume I need to change the host number for starters.

 

Thanks

 

 

  <hostdev mode='subsystem' type='scsi' managed='no'>
      <source>
        <adapter name='scsi_host3'/>
        <address bus='0' target='0' unit='0'/>
      </source>
      <alias name='hostdev0'/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </hostdev>

So I added the above code to the xml before </devices> and the DVD drive still did not appear in the VM. I changed the host number to "2" and tried setting the controller value to '0', '1' and '2' but still the DVD drive didn't register in the VM. 

 

I checked the device manager each time and the drive was not present. I also upgrade to the latest stable (6.8.2) which also did not resolve the issue. 

 

The drives do appear in the BIOS and are connected directly to the motherboard. 

 

There doesn't seem to be many threads about passing through a SATA connected optical drive to a VM leading me to think that I'm doing something wrong. I imagined that after connecting them I would be able to select them from the VM template but they don't appear there either. 

 

Does anyone else have a SATA connected optical drive passed through to their VM?

Try adding this above </device> and see if you can pass through the 1st drive.

<controller type='scsi' index='1' model='virtio-scsi'/> 
<hostdev mode='subsystem' type='scsi'> 
   <source> 
     <adapter name='scsi_host2'/> 
     <address type='scsi' bus='0' target='0' unit='0'/> 
   </source> 
   <readonly/> 
   <address type='drive' controller='1' bus='0' target='0' unit='0'/> 
   </hostdev>

Thanks mate,

 

Tried that and get this error when I save: XML error: Multiple 'scsi' controllers with index '1'

Can you copy-paste the xml of your VM please.

Use the code function (the </> button next to smiley button) so things are formatted correctly.

Please find attached. It's all working in this configuration just not the 2 DVD drives. Thanks 

 

I think its back to the original code before I started mucking around.

I think it's because model = 'lsilogic'. I think the virtio driver needs model='virtio-scsi'.

Use the edited xml at end of post and see how it goes.

Note that you will need to go into Device Manager (in Control Panel) to install driver for anything that doesn't have driver (scsi driver can be found on the virtio driver iso)

Mate, you're a legend! That got [2:0:0:0] working.

 

I tried flying solo to get [6:0:0:0] going. I added the following just above the membaloon line

 

  </hostdev>
        <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x06' slot='0x00' function='0x0'/>
      </source>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x0a' function='0x0'/>
    </hostdev>

but it returned the following error. "XML error: Attempted double use of PCI Address 0000:00:0a.0"

 

Any idea what I should change to get this one going?

 

Thanks again

Try this xml to see if both 2:0:0:0 and 6:0:0:0 work

Yes they both work now. Much appreciated. I wish I understood why!

 

The magic is in these sections of the xml:

...
    <controller type='scsi' index='0' model='virtio-scsi'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x0b' function='0x0'/>
    </controller>
    <controller type='scsi' index='1' model='virtio-scsi'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x0c' function='0x0'/>
    </controller>
    <controller type='scsi' index='2' model='virtio-scsi'>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x0d' function='0x0'/>
    </controller>
...
    <hostdev mode='subsystem' type='scsi' managed='no'>
      <source>
        <adapter name='scsi_host2'/>
        <address bus='0' target='0' unit='0'/>
      </source>
      <readonly/>
      <address type='drive' controller='1' bus='0' target='0' unit='0'/>
    </hostdev>
    <hostdev mode='subsystem' type='scsi' managed='no'>
      <source>
        <adapter name='scsi_host6'/>
        <address bus='0' target='0' unit='0'/>
      </source>
      <readonly/>
      <address type='drive' controller='0' bus='0' target='0' unit='0'/>
    </hostdev>
...

 

What the code does is that it creates virtualised scsi devices for the VM (the 1st section) and then connect the host scsi to those virtualised scsi devices (the 2nd section).

Some hints to help you understand the code better:

  • You have 1 redundant virtualised scsi device
  • Your scsi_host2 is connected to the 2nd scsi device and scsi_host6 is connected to the 1st scsi device

You've gone above and beyond mate. 

 

When I was researching NAS OS's a decade ago this forum/community was a big factor in my decision to choose Unraid. I'm pleased that I can still say the same today.
