According to qemu-kvm/qerror.c all messages start with a capital
"Device ", but the current code only scans for the lower case "device ".
This results in "virDomainUpdateDeviceFlags()" to not detect locked
CD-ROMs and reporting success even in the case of a failure:
# virsh qemu-monitor-command "$VM" change\ drive-ide0-0-0\ \"/var/lib/libvirt/images/ucs_2.4-0-sec4-20110714145916-dvd-amd64.iso\"
Device 'drive-ide0-0-0' is locked
# virsh update-device "$VM" /dev/stdin <<<"<disk type='file' device='cdrom'><driver name='qemu' type='raw'/><source file='/var/lib/libvirt/images/ucs_2.4-0-sec4-20110714145916-dvd-amd64.iso'/><target dev='hda' bus='ide'/><readonly/><alias name='ide0-0-0'/><address type='drive' controller='0' bus='0' unit='0'/></disk>"
Device updated successfully
