Description Sandro Bonazzola 2013-12-03 09:46:23 UTC 
Description of problem:
now that uploadVolume has been removed, downloadImage must be used in its place.
Actually for downloading an image from a local path it should be used method http with URL using file:// protocol.

It would be better having a method local requiring a file path instead.
Comment 1 Federico Simoncelli 2013-12-03 09:55:27 UTC 
Technically it's not hard to implement, we could support something like:

 downloadImage({'method': 'local', 'path': '...'}, spUUID, sdUUID, imgUUID)

(probably based on dd)
Comment 2 Sandro Bonazzola 2013-12-03 12:16:34 UTC 
raising severity since http + file:// seems not working (bug #1037584)

According to bug 1034777 comment 6 there's no need for this in 3.3.0. You can use uploadVolume, provided that the client connection doesn't timeout.
Comment 6 Ayal Baron 2013-12-24 08:21:45 UTC 
This should be covered as part of the work for storing OVFs on any domain.
Comment 7 movciari 2014-01-13 11:54:59 UTC 
how comes this is for 3.4, if it blocks  https://bugzilla.redhat.com/show_bug.cgi?id=1034777 which is targeted for 3.3?

As you can see Bug 1034777 is ON_QA so clearly it is not blocked by this bug.
Comment 11 Sandro Bonazzola 2014-05-14 11:34:51 UTC 
Hi, Liron, I can't access referenced patch 23197.
Where may I find the changes for using downloadImage verb for file:// protocol ?
