If you want to use the native functionality, you have to passthrough the drive (depending on the your device usb or pci sata-hardware). If your drive is attached via usb, you can try passthrough the usb-device, if it is connected via sata, you have to passthrough the sata-pci-device.

It is connected via PCI IDE controller (Silicon Image, Inc. PCI0680 Ultra ATA-133 Host Controller). Is it possible to passthrough it?

Correct, most of the unlocked 'K' models do not support VT-d: http://ark.intel.com/products/65520/Intel-Core-i5-3570K-Processor-6M-Cache-up-to-3_80-GHz ^ permalink raw reply [flat|nested] 11+ messages in thread

I changed device from 'cdrom' to 'lun': <disk type='file' device='lun'> also tried <disk type='block' device='lun'> but in both cases VM does not start: Error starting domain: unsupported configuration: disk device='lun' is only valid for block type disk source. ^ permalink raw reply [flat|nested] 11+ messages in thread

Thanks, it worked! VM now sees the lightscribe drive, Just for the information, the following works: <disk type='block' device='lun'> <driver name='qemu' type='raw'/> <source dev='/dev/sr0'/> <target dev='sda' bus='scsi'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> ^ permalink raw reply [flat|nested] 11+ messages in thread
