1. We try to connect to the remote host: 2. Connectioin fails with DNS resolving error 3. self._destServer is not initialized becuase of 2 4. Code in _recover fail when access self._destServer We should fix the initialization to avoid this error, but it will fix your issue, which is DNS error. Maybe the address of the destination vm is wrong, or you have DNS issues in your environment? Adding Francesco.
