This message is in response to an earlier thread regarding a UI plugin to upload ISO files. Like the original poster, Lucas, I began work on a UI plugin to allow uploading ISO files through a UI plugin. After reading the previous thread I'm re-thinking the architecture.
It was suggested that the recommended approach to upload files to a storage domain is through the VDSM API [1]. I'm pretty familiar with the oVirt REST API but have been unable to find documentation regarding accessing the VDSM API. Should the VDSM API be accessible by a UI plugin? If so, is there documentation available to do so?

Basically you have to: 1. Use the vdsm xmlrpc/jsonrpc to create an image 2. Use the vdsm http api to upload the data to the image. This will create a task and return a task id. 3. Use the vdsm xmlrpc/jsonrpc api to check the task status, and clear the task when done
The xmlrpc/jsonrpc api is documented here:
http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=blob;f=vdsm/rpc/vdsmapi-schema.j...
You can check the code for upload here:
http://gerrit.ovirt.org/gitweb?p=vdsm.git;a=blob;f=vdsm/rpc/BindingXMLRPC.py...
I assume the upload will be done via a servlet on the engine, not directly by the ui plugin accessing vdsm. worth discussing your plans here, to make sure architecture/security are correct.
I was planning on using a python CGI script which would accept the upload via POST from the UI plugin. The file would be stored in /tmp on the engine host. After the file was successfully uploaded, the CGI script would send a POST to a python HTTP server (BaseHTTPServer, also running on engine host) with the filename and storage domain information. This python script would then take care of mounting the storage domain and copying the file to the appropriate location. This was my initial approach, I plan on checking out the VDSM API as well.
