Description melchiaros 2011-09-06 15:58:30 UTC 
Description of problem:
I´ve installed yesterday a windowsXPSP2 guest and upgraded it to SP3.
Today I want to start with virt-manager the windows XP guest and get from virt-manager and error message:

Error starting domain: unable to open disk path /dev/sr0: Kein Medium gefunden

It is not able to find the .raw anymore, but it is still in it´s folder like yesterday.
-> I´ve installed in not in root. Instead in /home/user/Vorlagen/windowsXP_old.raw

That may cause the problem. But for my linux guest it works.-> Only windows iis affected with this.

Hmm, empty /dev/sr0 shouldn't cause qemu to fail to start... I'll try and reproduce
Comment 3 Cole Robinson 2012-01-29 20:20:01 UTC 
I can't reproduce this issue. If you can still reproduce, please reopen, and provide the output of following commands for the busted VM

sudo virsh --connect qemu:///system start <vmname>
sudo virsh --connect qemu:///system dumpxml <vmname>

also, does the following command produce a similar error:

qemu-kvm -cdrom /dev/sr0
