Change subject: core: protocol fall back for older vdsms ...................................................................... core: protocol fall back for older vdsms When we try to install new host which only supports xmlrpc and we have cluster with compatibility level set to 3.5+ the code will fail. Solution for this issue is attempting to connect by using jsonrpc and if it fails falling back to xmlrpc.
