Hi folks

Host - Fedora 12 64bit
VM (guest) - Windows Server 2008 64bit


Fail to attach CDWriter.


$ sudo virsh -c qemu:///system start vm06_wser08
Domain vm06_wser08 started


$ cat VM/DEV/cd.xml
<disk type="block" device="cdrom">
<target dev="hdc" bus="ide"/>
<readonly/>
<source dev="/dev/sr0"/>
</disk>


$ sudo virsh attach-device vm06_wser08 VM/DEV/cd.xml
error: Failed to attach device from VM/DEV/cd.xml
error: server closed connection


$ sudo tail /var/log/messages

If I put following content on vm06_wser08 ; (cd.xml)
<disk type="block" device="cdrom">
<target dev="hdc" bus="ide"/>
<readonly/>
<source dev="/dev/sr0"/>
</disk>


Then it works. CDWriter can be attached to Vista. But I must insert the CD on the drive before starting vm06_wser08. Otherwises it complains.


Please help.  TIA
