Xen Enterprise ISO Libary Bug

If you are wondering why your vm isn't able to access the content of an iso file attached through a iso library wich you are able to browse and attach with no error in any log file it might be the case that you misstyped your path to the library. For example i had // but the real path case-sensitive is //

It took me quite some time of investigation to figure out that this was the problem. It was quite hell and really annoying since there doesn't appear any error in any of the logfiles and the worst part is that you are able to see the iso images in your xen center, only your vm isn't able to access the content.
