A different solution is to use ESAMON to feed MXG. That way, MXG gets all the network

The short answer is no, there is no such conversion field in VM itself.
Of course, if you are running a guest like MVS under VM, that support

LDUBUF would not have helped, for once it was STORBUF. Since you have overallocated
