Created attachment 828342 [details] nova logs Description of problem: The nova migration fails while the instance: - Has volume attached. - The instance is active/ shutdown. - The instance just been created with no volume attached. The main nova compute node has ssh access to the secondary node, the Selinux and iptables are not a factor in the failure of the action. Version-Release number of selected component (if applicable): openstack-nova-compute-2013.2-5.el6ost.noarch openstack-nova-scheduler-2013.2-5.el6ost.noarch python-novaclient-2.15.0-1.el6ost.noarch python-nova-2013.2-5.el6ost.noarch openstack-nova-api-2013.2-5.el6ost.noarch openstack-nova-conductor-2013.2-5.el6ost.noarch openstack-nova-novncproxy-2013.2-5.el6ost.noarch openstack-nova-cert-2013.2-5.el6ost.noarch openstack-nova-common-2013.2-5.el6ost.noarch openstack-nova-console-2013.2-5.el6ost.noarch The OS is: Red Hat Enterprise Linux Server release 6.5 How reproducible: everytime Steps to Reproduce: 1. create an instance 2. migrate the instance (either when the instance is active or shutdown). 3. Actual results: the instance is in error state Expected results: the instance should move to the other nova-compute node and should be available. Additional info:
In the log I can see the message "Host key verification failed". Before using resize/migrate without shared storage the hosts must be configured to allow passwordless access for user nova so the image can be copied from one host to the other using ssh. You can find the exact configuration steps in: http://fedoraproject.org/wiki/Getting_started_with_OpenStack_EPEL#Migrate_and_Resize *** This bug has been marked as a duplicate of bug 1028186 ***
