From: Chen Hanxiao <chenhanxiao(a)gmail.com&gt; If we insert or eject a CD-ROM/floppy device by: 'virsh change-media VM --eject/--insert some.iso --live', and the original CD-ROM device was configed with a boot order, we may get: unsupported configuration: boot order 2 is already used by another device We just updated 'source file' section rather than hotplug a new device. This check should be skipped in this case.
