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.
