AFAIK MSI interrutps are still not by Xen at the present time.  You might like 
to ask about this on the xen-devel mailing list as people there may know more 
specifics...  I believe there's a general intent to add MSI support at some 
pointc, but I don't know how advanced those efforts are.

Cheers,
Mark
