I'm trying to dump informations about console with the following code:

console_type = connection.follow_link(console_type) buf = None writer = None buf = io.BytesIO() writer = xml.XmlWriter(buf, indent=True) ConsoleWriter.write_one(console_type, writer) writer.flush() print buf.getvalue() But i got the following result :

If I add print console_type.__dict__, it contains:

Did I miss something, or is that a but with the console writer ?
The problem is that you are trying to use the ConsoleWriter class to write something that isn't a Console. The GraphicsConsoleService.list method returns a list of objects of type GraphicsConsole, not Console. So you need to use GraphicsConsoleWriter. Note that once you have the virtual machine you can obtain the graphics consoles directly using the 'follow_link' method, no need to use the intermediate services. For example: vm = ... console = connection.follow_link(vm.graphics_consoles)[0] Remember that the WhateverWriter classes are an implementation detail, and that they may change or disappear without notice. If you need to convert objects to XML use the generic Writer.write method that will be introduced by this patch: Add generic writer https://gerrit.ovirt.org/75699 Ondra, in what version of the SDK do we plan to include that enhancement? I also wonder why do you need to convert objects to XML explicitly. Can you elaborate on what is your need?
