Open Stack

Hello,
Running OpenStack Grizzly on Ubuntu server 13.04  dpkg -s nova-api shows 
the version as 1:2013.1-0ubuntu2
I am trying to resize a running instance.  Using  the OpenStack Compute 
Administration Guide found at 
http://docs.openstack.org/trunk/openstack-compute/admin/content/nova_cli_resize.html 
I was unable to do so.  I issue the commands as shown and have also 
tried using --debug (nova --debug resize 
1d3627cd-6256-48ca-8d3f-82cf07c4eb28 4)
Then afet some large anmmount of text scrolloing quickly by on screen I get:
INFO (connectionpool:191) Starting new HTTP connection (1): 192.168.100.51
DEBUG (connectionpool:283) "POST 
/v2/9629938f9e1f4f56a98db3438c522acd/servers/1d3627cd-6256-48ca-8d3f-82cf07c4eb28/action 
HTTP/1.1" 202 0
RESP: [202] {'date': 'Tue, 21 May 2013 19:40:51 GMT', 'content-length': 
'0', 'content-type': 'text/html; charset=UTF-8'}
RESP BODY:

I then check that status with nova list --all -tenants and the instance 
shows as active rather than the status RESIZE as would be expected based 
on the doc, but nothing has changed.   Any pointers to what I might be 
doing wrong?

Thanks,
