  Virsh first opens a connection to an hypervisor, and then tries to 
run the commands (can be multiple one for example in shall mode).
What you're suggestion is to do some introspection on the XML, and then
change the way virsh works just for that command, that's not that
trivial nor very clean.

  On the other hand what was improved recently is that if a command like
create uses the "wrong" hypervisor type in the XML we are now reporting
the expected hypervisor type instead of just failing the operation as
you got. If you try with 0.9.4-rc1 it should have that improvement,
