Re: [libvirt] [PATCH] virsh: Correctly detect inserted media in change-media command

https://bugzilla.redhat.com/show_bug.cgi?id=1250331 It all works like this. The change-media command dumps domain XML, finds the corresponding cdrom device we want to change media in and returns it in the xmlNodePtr form. This way we don't have to bother with keeping all the subelements or attributes that we don't care about in the XML that is fed back to libvirt for the update API. Now, the problem is we try to be clever here and detect if disk already has a source (indicated by <source/> subelement). However, bare fact that the element is there does not mean disk has source. The element has some attributes and only if @file or @dev is within them disk has source. Any other attribute is meaningless for our purpose now. Make our clever check better.
