You should give us /var/log/nova/{nova-api,nova-compute,nova-network}.log.
But please, use http://paste.openstack.org/, dont fill the email with logs
entry. Also paste /etc/nova/nova.conf and /etc/nova/api-paste.ini
Check the user and permissions of /etc/nova
and my last shot in the dark: flush the nova db and restart all services
$ mysql -uroot -p'MYSQLPASSWD' -e 'drop database nova;'
$ mysql -uroot -p'MYSQLPASSWD' -e 'create database nova;'
$ nova-manage db sync
$ for a in libvirt-bin nova-network nova-compute nova-api nova-objectstore
nova-scheduler nova-volume nova-consoleauth nova-cert; do service $a
restart; done
