Additional info:
Error:
TRACE nova.openstack.common.rpc.amqp Stdout: ''
2013-05-29 16:52:35.233 18605 TRACE nova.openstack.common.rpc.amqp Stderr: 'Host key verification failed.\r\n'
2013-05-29 16:52:35.233 18605 TRACE nova.openstack.

So I created the host keys for nova user with the command: ssh-keygen -f nova and then renamed them to id_rsa and id_rsa.pub and then put them to ~nova/.ssh/

Also, I copied the files /root/.ssh/known_hosts and /root/.ssh/authorized_keys to ~nova/.ssh/ on both machines

Then I changed the file permissions to nova:nova

Then comes the error:This account is currently not available.\n

So I edited the file /etc/passwd on both the machines and then changed the line

nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/sbin/nologin

to

nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/bin/bash

Now migration works.. But his is a tedious task.
