OpenStack version: Icehouse
Issue: fail to resize
Setup: 3 nodes, namely Controller, Compute and Network; with nova-compute
running solely on Compute node.
Steps to reproduce:
1. Create an instance using image cirrus 0.3.2.
2. Verify instance is running: nova list
3. Resize the instance: nova resize cirrus 2 —poll
4. Verify the resize: nova list
5. Note that the server status is ACTIVE instead of VERIFY_RESIZE.
6. Check nova-scheduler.log at Controller node and note the error.

NOTE: I tried setting "allow_resize_to_same_host=true” and
“allow_migrate_to_same_host=true” in all nova.conf files and
restart nova services, but still saw the same issue.
Thanks,
