I use the following xml with wbemcat or wbemexec to make the method
call:

  <?xml version="1.0" encoding="UTF-8"?>
  <CIM CIMVERSION="2.0" DTDVERSION="2.0">
  <MESSAGE ID="5" PROTOCOLVERSION="1.0">
  <SIMPLEREQ>
  <METHODCALL NAME="MigrateVirtualSystemToHost">
  <LOCALINSTANCEPATH>
   <LOCALNAMESPACEPATH>
    <NAMESPACE NAME="root"/><NAMESPACE NAME="virt"/>
   </LOCALNAMESPACEPATH>
   <INSTANCENAME CLASSNAME="Xen_VirtualSystemMigrationService">
    <KEYBINDING NAME="CreationClassName">
     <KEYVALUE VALUETYPE="string">Xen_VirtualSystemMigrationService</KEYVALUE>
    </KEYBINDING>
    <KEYBINDING NAME="SystemName">
     <KEYVALUE VALUETYPE="string">foo.bar.com</KEYVALUE>
    </KEYBINDING>
   </INSTANCENAME>
  </LOCALINSTANCEPATH>
  <PARAMVALUE NAME="ComputerSystem">
    <VALUE.REFERENCE>
      <INSTANCENAME CLASSNAME="Xen_ComputerSystem">
        <KEYBINDING NAME="CreationClassName">
  	<KEYVALUE VALUETYPE="string">Xen_ComputerSystem</KEYVALUE>
        </KEYBINDING>
        <KEYBINDING NAME="Name">
  	<KEYVALUE VALUETYPE="string">pv0</KEYVALUE>
        </KEYBINDING>
      </INSTANCENAME>
    </VALUE.REFERENCE>
  </PARAMVALUE>
  <PARAMVALUE NAME="DestinationHost" PARAMTYPE="string">
  <VALUE>
    localhost
  </VALUE>
  </PARAMVALUE>
  </METHODCALL>
  </SIMPLEREQ>
  </MESSAGE>
  </CIM>

You'll need to change "pv0" to the name of a valid domain, and the
"localhost" to a valid destination host (or leave it as localhost to
test on loopback).

Note that unless you have a key setup, you'll need to type root's
password on the CIMOM's stdin.

You should be able to tweak the above to test the IsMigratable flavor
as well.
