[ovirt-devel] Re: How to upload files via oVirt SDK

Moved discussion from private chat to the proper place. Please use the mailing list instead of private email or chat. Yes upload_disk.py is assuming oVirt 4.4, as part of ovirt-4.4 release. However imageio client library used by upload_disk.py tries to support any version of imageio, both proxy and daemon so the upload should work with any version. If it does not work please file ovirt-imageio bug. upload_disk.py assumes that the sdk supports the "format" attribute of ImageTransfer. This should be available since 4.3 and should work. Common issues with old upload code are: - using proxy_url instead of transfer_url - using signed_ticket and Authorization header ImageTransfer.proxy_url should be used only when you cannot access ImageTransfer.transfer_url. It also provides worse performance and partial functionality. The proxy was added to support upload and download from the UI, but programs should avoid it if possible. ImageTransfer.signed_ticket and Authorization header were used only up to 4.2 (or maybe 4.1). There is no need to send this header to the proxy since it does not use it. The daemon never support this header. Note that imageio client library import is going to change in 4.4. release. In 4.3 it was via: from ovirt_imageio_common import client While in 4.4 it will be: from ovirt_imageio import client Due to restructure of the ovirt-imageio deployment in ovirt-imageio 2.0. This affects only python 3 version, and only oVirt 4.4 alpha. To support both 4.4. alpha and 4.4 final release you can do: try: from ovirt_imageio_common import client except ImportError: from ovirt_imageio import client If you don't care about supporting early alpha versions you can have: python2: from ovirt_imageio_common import client python 3: from ovirt_imageio import client Nir
