   Hi,

That would be great.  When adding the xen bits initially I've tried to 
avoid hard dependencies on specific xen versions.  There are some ifdefs 
in the qemu code to support compiling with various xen versions (IIRC 
3.1 -> 3.4 worked last time I've tried).  I think the minimum supported 
range of xen versions should be the ones still actively maintained by 
xensource (I think this is 3.4, 4.0 and unstable right now).  Supporting 
even older versions would be nice to have.

cheers,
   Gerd
