Xen devel - Oct 2006 - [RFC] Disallowing xm operations on HVM domains

Certain operations, such as for example ''xm block-attach''
don''t work on
HVM domains and should be intercepted in xend. The following patch shows 
an example of how this could be done. When run, unfortunately the usage of 
block-detach is still shown.
