* src/vm/VirtualMachine.cc (insert): Add “EMULATOR” to the list of
  VM attributes understood by opennebula.

* src/vmm/LibVirtDriverKVM.cc (deployment_description_kvm): Get
  “EMULATOR” from VM template first, then from default and finally from
  hardcoded path.

Thanks Vladislav Gorbunov for the patch
