I don't have a scsi controller in my XML so I added

<controller type='scsi' index='1' model='virtio-scsi'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' 
function='0x0'/>
</controller>

(0x0) is not in use)

And the following hostdev definition..

<hostdev mode='subsystem' type='scsi'>
     <source>
     <adapter name='scsi_host1'/>
     <address type='scsi' bus='0' target='0' unit='0'/>
     </source>
     <readonly/>
     <address type='drive' controller='1' bus='0' target='0' unit='0'/>
</hostdev>

#lsscsi
[1:0:0:0]    cd/dvd  ASUS     DRW-24D5MT       2.00  /dev/sr0

But windows won't boot .. the boot screen just keep on loading.

What I don't understand is why to passthrough as scsi and not SATA
