Straightforward --alinone install via native Havana repo with no problems Recreating external network, OVS bridge "br-ex" and p37p1 as OVS port

Reboot.

[root@openstack1 neutron(keystone_admin)]# nova  net-list

reports server error

[root@openstack1 neutron(keystone_admin)]# nova  servicelist

shows state down everywhere

/var/log/neutron/server.log is attached.

I believe to fix it , but it's just a hack seems to connected to bug 1051593

[boris@openstack1 ~]$ sudo su -

[root@openstack1 ~]# ls -l /etc/neutron/neutron.conf
-rw-r-----. 1 root neutron 14386 Jan 12 16:15 /etc/neutron/neutron.conf

[root@openstack1 ~]# vi /etc/neutron/neutron.conf

Uncommented :

api_paste_config = api-paste.ini

Updated /etc/rc.d/rc.local :-

[root@openstack1 neutron(keystone_admin)]# cat /etc/rc.d/rc.local
!/bin/sh

losetup -f /var/lib/cinder/cinder-volumes && vgchange -a y cinder-volumes && systemctl restart openstack-cinder-volume.service

ifdown br-ex ;

ifup br-ex ;

service network restart ;

-- Three times would be enough in general --

systemctl restart qpidd.service ;
systemctl restart qpidd.service ;
systemctl restart qpidd.service ;
service openstack-nova-compute restart ;
exit 0

Then in openstack-status report instead of server errors I get :-

Bug 1052096: https://bugzilla.redhat.com/show_bug.cgi?id=1052096

In mean time due to https://bugzilla.redhat.com/show_bug.cgi?id=1051593

I created /etc/rc.d/rc.local ( works on demo box pretty stable ) , as soon as bugs will be fixed I will just remove it

ifdown br-ex ;

ifup br-ex ;

service network restart ;

systemctl restart qpidd.service ;

service openstack-nova-compute restart ;

Gluster backends for Nova,Glance,Cinder are implemented for --allinone instance and work fine

$ df -h
