If i am not mistaken there is the case:


Plugin           current imagename    action

lvmthin:        base-100-disk-1         old_base =

LVMplug:  -> vm-100-disk-1            not working due to collision

LVMplug:  -> vm-100-disk-2            call find_free_disk()

lvmthin    -> base-100-disk-2          != old_base

But I think we could also just skip this case and remove the 
$oldbasename completly.
