There must be another way (it doesn't have to be calling the official 
C++ API which offers a method to pause a VM, which internally calls 
VMR3Suspend). Your code must be located in the VM process anyway, so it 
should have some starting point (and no, there's no function call to 
calculate PUVM from the VM UUID/name).

Who's calling your code? You should be able to get what you need...

Too little information to help, I'm afraid.
