<disk type="block" device="cdrom">

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

I second this bug report. Just yesterday I tried to attach a CDROM to an
already-running WinXP guest under qemu-0.12.1.2 with libvirt 0.7.5 using
virt-manager 0.8.2. virt-manager immediately dropped its connection and
refused to re-connect to the libvirtd socket. Futher investigation
showed that the libvirtd process had died.
Restarting libvirtd, stopping the VM, attaching the CDROM again, and
then re-starting the VM from scratch made the CDROM visible within the
guest, suggesting there is something not quite right with the dynamic
device attachment mechanism in libvirt.
ATB,
Mark.

FYI, libvirt issues shouldn't be reported here: libvirt-list@redhat.com
is better.
I can't reproduce with libvirt 0.7.6. If either of you can still
reproduce, can you run libvirtd under gdb, reproduce the crash, and
report a backtrace? More info here:
