Open Stack

Hello everyone,

I am trying to run DevStack on Ubuntu 14.04 in a single VirtualBox. An
error turns up  before it successfully starts. Yesterday I clarified this
question not  clearly enough，so I make a supplication for it. My steps are:
1), Git clone DevStack,
2), Copy devstack/local.conf.sample to DevStack folder and rename it to
local.conf.

the finished steps before the error turns up are listed as follows:

the final printed errors on terminal are:

Request Failed: internal server error while processing your request.
Neutron server returns request_ids:

I don't know whether it is  my wrong configuration of computer or the
server error, I wish someone can help me with the problem. thanks!
