With the testing I have done so far it looks like any change that is made seems to trigger some part of that customiztion and whatever it is is breaking it. I can watch the system boot and it definitely "reboots" very quickly then does a full boot. It seems like the vm tools are running their customization tasks which would rename the system. I haven't yet taken a look at the logs to see if I can tell just exactly what is happening but hopefully there is something traceable. I'll open up a support case.
