Note that you don't have to add a scsi <controller> if you already have
one. You can add the drive to the existing one.
Either that method won’t work anymore or my config is bad .. im not really sure what to
put in controller, target, bus and unit ..
So there are two addresses for the <hostdev>.
The one under <source> should be set to the address of the CDROM drive
on the host. It can be obtained e.g. using lsscsi:
# lsscsi
[2:0:1:0] disk ATA ST3500418AS CC38 /dev/sda
[3:0:0:0] cd/dvd HL-DT-ST DVDRAM GH24NSB0 LN00 /dev/sr0
(so 'scsi_host3'(adapter) and bus='0' target='0'
unit='0')
The second address <address type='drive> is the address on the VM's bus.
<address type='drive' controller='1' bus='0' target='0'
unit='0'/>
You set 'controller' to the 'index' attribute of the <controller>
you
want it to attach to. The 'bus' should be '0'. If you have other devices
on the controller, pick an unused 'target' value and 'unit' should be
'0'.
