OpenStack Havana Docs for enabling networking missing steps for creating br100

[Geoffrey]

I've been following the Havana docs for installing openstack on RHEL based systems, and I've gotten everything up to enabling networking on the compute node to work.

No where does it tell me anything about creating the bridge on the node or how to manage it, and when I rung ifconfig, br100 is no where on the list of devices. I do get virbr0 and virbr0-nic from installing libvirt though.

Hi Geoffrey,

br100 should be automatically created by nova-network

once you've configured the nova.conf for networking and restarted the nova-network service, it should appear.

[Anne Gentle (annegentle)]

When I tested on Ubuntu, I had to manually create br100. It seems like the
nova network-create command isn't creating the bridge? Please reply here if
you know if it's necessary.

    """Flat networking with dhcp.

    FlatDHCPManager will start up one dhcp server to give out addresses.

[Tom Fifield (fifieldt)]

it might be that the bridge is created on first vm boot, instead of on service restart, but it is definitely created by nova-network.

[Geoffrey (yourapanzy91)]

It definately did not create the bridge of first vm boot, as I recieved an error about the network not existing when booting an instance.

FWIW, I'm going to the guide again to make sure I did not forget any step. But in the many times I've been following the docs, I never saw a br100 created even after doing service openstack-nova-network restart.

[Geoffrey (yourapanzy91)]

So I just ran through the havana docs again (http://docs.openstack.org/trunk/install-guide/install/yum/content/ch_basics.html)

And I've arrived at the point of nova-network. It did not create br100.

which distro are you using?

[Geoffrey (yourapanzy91)]

I'm using centos 6.4.

[Tom Fifield (fifieldt)]

Thanks Geoffrey.

These install instructions haven't been tested at all on Centos, so I'm going to have to set up a centos machine to see what I can replicate and fix them.

That could take a few days.

In the meantime, if you create a bridge in your interfaces config, does it look like it'll get configured?

[Tom Fifield (fifieldt)]

Actually, you might be able to help us with ticking off the earlier sections ... did the Identity Service and Image Service sections appear to work for you?

https://wiki.openstack.org/wiki/HavanaDocTesting

[Geoffrey (yourapanzy91)]

I found some "hidden" docs that describe how to make the bridge.
Unfortunately I was no successful in getting anything to boot on the node
(an iptables problem).

I did notice that the virtual bridges and iptables rules from libvirt are
fully in place.

Currently away from my workstation where I was testing this so I cannot
provide exact details and/or logs until October 21.

Hi,

I have installed a centos 6.4 compute node and confirm that the br100 is automatically created on installing nova-network.

However, there were some problems with the configuration in the install causing nova-network to not start - I have put in a patch to fix these:

https://review.openstack.org/#/c/52748/

[Tom Fifield (fifieldt)]

To fix your install, open /etc/nova/nova.conf and comment out routing_source_ip

you probably also want to run the commands in here:

 145 <screen os="centos"><prompt>#</prompt> <userinput>service libvirtd start</userinput>
   146 <prompt>#</prompt> <userinput>service messagebus start</userinput>
   147 <prompt>#</prompt> <userinput>chkconfig libvirtd on</userinput>
   148 <prompt>#</prompt> <userinput>chkconfig messagebus on</userinput>
   149 </screen>

Hi all!

I am following the guide for CentOS and no br100 is created??

What should I do in order to proceed with the network create?

Best,

G.
