I didn't find a way to find the writer that correspond to a given type. Is there a way to do that, or it's up to the end user to manually manage this mapping ?

Yes that is missing. We have it for reading, but not for writing. This patch should address that:

Add generic writer https://gerrit.ovirt.org/75699

Please open a bug so that we can decide what version should contain this fix.

Note that you should try to avoid using directly the writer/reader classes, as they are an internal implementation detail and may change in the future. The contract for reading/writing is using the Reader and Writer classes. For example, to generate the XML for an object (once the patch is merged):

from ovirtsdk4 import types from ovirtsdk4 import writer from ovirtsdk4 import writers

vm = types.Vm( id="123", name="myvm", ... )

xml = writer.Writer.write(vm)

print(xml)

The above was not complete clear. The ovirtsdk4.writer.Writer and ovirtsdk4.reader.Reader classes are part of the contract of the SDK, it is safe to use them. The specific writer/reader classes, for example VmReader or VmWriter, are not part of the contract, and they may change in the future without notice, so try to avoid using them directly.
