You'll want the DestinationSystem to be the reference of KVM_HostSystem 
on the target machine.

So, something like:

   <PARAMVALUE NAME="DestinationSystem">
     <VALUE.REFERENCE>
       <LOCALINSTANCEPATH>
	<LOCALNAMESPACEPATH>
	  <NAMESPACE NAME="root"/>
	  <NAMESPACE NAME="virt"/>
	</LOCALNAMESPACEPATH>
	<INSTANCENAME CLASSNAME="KVM_HostSystem">
	  <KEYBINDING NAME="CreationClassName">
	    <KEYVALUE VALUETYPE="string">KVM_HostSystem</KEYVALUE>
	  </KEYBINDING>
	  <KEYBINDING NAME="Name">
	    <KEYVALUE VALUETYPE="string">target_sys_hostname</KEYVALUE>
	  </KEYBINDING>
	</INSTANCENAME>
       </LOCALINSTANCEPATH>
     </VALUE.REFERENCE>
   </PARAMVALUE>
