Hi Vish,

Thanks for the quick reply. I have passwordless ssh between the compute hosts 
but could you explain me the first option. When I resize, will the instance 
redeploy on a different compute node?

Do I need to specify this flag allow_resize_to_same_host=true in nova.conf of 
the compute node?



Regards,

Krishnaprasad

2 requirements:

1) hostname for compute hosts resolve properly
2) passwordless ssh works between compute hosts.

Hallo All,

I am trying to use the Nova API (POST call) for changing the flavor information 
(to resize) from m1.tiny to m1.medium. Even though the API is successful (202 
Status code), on the Horizon GUI I could see that the Status is Error and the 
task state is Resize Prep. I am passing the Auth Token along with the Body 
information in the form of json as inputs to the API. I have referred this 
URI<http://docs.openstack.org/api/openstack-compute/programmer/content/resizing-servers.html>
 for passing the body information.

I am using OpenStack ESSEX and can I get to know is there any configurations 
that I need to do in order to get this working?

Thanks
Krishnaprasad
