It's possible that setupcommand failed.
I want to get the following information:
1. which hypervisor are you using? Xenserver 6.*, xcp?
2. Possible set a breakpoint at XcpServerDiscoverer.java:634? What's the

3. Possible set a breakpoint at CitrixResourceBase.java -> protected
SetupAnswer execute(SetupCommand cmd) {? What's the return value of this method?
