[one-users] Cannot access Sunstone after upload image 500Gb

Thu Sep 5 01:34:43 PDT 2013

Yes, I still experiencing the issue.
I really think that the problem is my network since I am using NFS for the
data transfer.

If I deploy a Persistent image, the deployment time would be fast.
Most of my image is using persistent and it has no problem at all

If I deploy a non-persistant image, the deployment time would be slow.
This holds true as non-persistent image would be copy to hypervisor and
this is my problem.
For a non-persistent image of 8Gb, it would take about 1/2 hour to deploy
(from prolog to running)
While deploying, the sunstone server seems slow other people who want to
login also takes much longer time
