[libvirt] [test-API][PATCH v2] Add volume upload and download cases
Wayne Sun
gsun at redhat.com
Sun Jan 6 09:37:34 UTC 2013
The cases only cover dir volume testing.
v1:
* test download storage volumes using storage download API.
* test upload storage volumes using storage upload API.
For upload case, only raw volume format is supported, other
format will fail.
The offset and length value should be chosen from 0 and
1048576, because upload size is set as 1M.
* both case use blocking stream.
* sample conf is added.
v2:
* move digest function to utils
* rename cases with prefix 'dir_' to emphasise that they are
only for dir vol testing
