[Xen-users] CD/DVD drive in DomU

Hi everyone,

I was just playing around with my Xen project again and tried to  
assign a physical CD/DVD drive to my Desktop DomU via the disk  
section in the config file, because I want to use it for CD and DVD  
reading and writing (like on a normal desktop). I tried 'phy:/dev/ 
scd0,scd0,r' and 'phy:/dev/scd0,scd0:cdrom,r', which resulted in the  
device not showing up in /dev in the DomU at all, and 'phy:/dev/ 
scd0,hdc:cdrom,r' and 'phy:/dev/scd0,hdc,r', resulting in the device  
showing up but wodim -scanbus not finding it (which would be  
essential for CD/DVD writing) and no auto-mounting.
After a bit of research, I tried to pass the IDE controller to that  
DomU, which resulted in the CD/DVD drive not being available in  
either of the VMs and a system crash when destroying down the Desktop  
DomU. I already checked for possibly overlapping IRQs, but as far as  
I could see, when assigning the IDE controller to that DomU, it is  
then the sole user of it.
Am I doing something wrong here, or is there any better way to  
accomplish this? Ideally, the sollution wouldn't have to depend on  
passing the IDE controller to the DomU, since I am planning on  
replacing the current IDE DVD-Writer with a SATA BD-Combo and my  
board only has one SATA controller (and I wouldn't like to buy a  
separate one). Any ideas on how to make this work?
Thanks,


Paul.

P.S.: Sorry for double-posting my last message, looks like my Mail  
client screwed up somewhere.
