I am trying to track down the problem.
OK, I have been able to reproduce the problem, is C, without Ruby. Attached is source code and XML file. Here is a sample output:

As you can see, it works OK first time, but the second time, returns the same UUID, lookup on which fails.
The problem is that you are not freeing the virDomainPtr object after you undefine the first VM. Libvirt caches virDomainPtr objects based on the 'name' value. So the second time around you are getting the cached handle. You are also leaking memory. You need to call virDomainFree(virDomainPtr dom) to actually release the handle.
