Hi, Thanks for your response. I don’t have a floating ip for the instance. I will check related to known_hosts file and related to fixed / floating IPs and will share the updates.

If I get it correctly, this means that the key on the compute nodes that was cached earlier has been changed. Can I get to know is this correct and how to get rid of this problem?

You should see messages in the compute log about it trying to do this. The error message there might give you a better idea of what failed. Yes resize will go through the scheduler and usually find a new compute node. The conf option does not force it to use the same host, so it is mostly just there for testing.

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?

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?
