# Node ID cf1ca06154147cb49b41fc56835ee2cffea31e32
# Parent 92127156ec49568f737b54ff093bdca56e877097
Added support for configuration file for xm, and use that to specify
contact and authentication details for the Xen-API server.
The default behaviour is still to use the existing legacy XML-RPC server.
