Thomas O'Dowd commented on CLOUDSTACK-3229:
-------------------------------------------

Prasanna helped me get instance launching up again on 4.2. 

Just tried saving a snapshot again.

On the UI, I get an ERROR popup:
     "Failed to create snapshot due to an internal error creating snapshot for 
volume 6."

On the management server I see:

On devcloud in the SMlog file, I see:

####

This shows a successful upload of the snapshot to the S3 server. You can see 
the plugin received 200 OK response and it exited with result true...

Looking at a bucket listing from the S3 server, I can see this snapshot was 
uploaded successfully also:

  $ ./list.py -B images

So, the S3 part looks good to me.

Right after uploading S3, is this next section in SMlog:

Still not working but very close perhaps?
