Thanks for the report Georg - looking into this immediately.

[Tom Fifield (fifieldt)]

Hi Georg,

I've read the code, and it seems like nova network-create is valid.

Is there a chance your python-novaclient package is out of date?

[Kodiak Firesmith (kfiresmith)]

Hello Tom.

So the deal here I think is that the documentation never covered the process of setting up the network bridge "br100".

My position is that yes, there are other documents to cover doing this sort of thing (the RedHat deployment guide comes to mind), but if this documentation strives to be a complete walk through, it should cover not only the creation of the software bridge device br100, but also should discuss the iptables needs in a multi-host Openstack configuration, including allowing all of the management ports needed such as 5000, 8774, 9292, and 35357.

[Tom Fifield (fifieldt)]

br100 is automatically set up by nova-network, you do not need to manually create it.

[Kodiak Firesmith (kfiresmith)]

Oh, OK then I stand corrected. I can't confirm this particular page of docs until a couple days from now, I'm still waiting on compute hardware to come in. I'll zip through this page when my gear arrives and come back to confirm if I can reproduce his complaints or not.

Thanks Tom!

[Tom Fifield (fifieldt)]

Thanks Kodiak!

I'll ensure the doc gets updated to make this clearer :)

Me too getting the following error

Seems tricky! Replace '-' with '_' and the error goes away.

For more info. check the command usage.

[Tom Fifield (fifieldt)]

Hi Armit,

This is very likely because your client is out of date.

Ensure that you have set up the appropriate packages for the Havana version of the client.

[Tom Fifield (fifieldt)]

Made a new bug for tracking the comment about firewall setup/ports etc: https://bugs.launchpad.net/openstack-manuals/+bug/1261617

the original bug report here appears to be invalid for havana, so will close it. Please post comments on the new bug for the firewall/port information, or here if it has been closed in error.

[Aswin mohanan (aswinmohanan001)]

Hi Amit,

Thank you for your comment on this, I got working that command by adding _ instead of -

BTW,

I am trying to create the floating ip address, but it seems it is adding ips but not listing, please have a look into the following snippet:

[root@server2 ~(keystone_admin)]# nova-manage floating create --ip_range=192.168.1.0/24 --pool Public
[root@server2 ~(keystone_admin)]# nova floating-ip-pool-list

[root@server2 ~(keystone_admin)]#

[Andreas Jaeger (jaegerandi)]

Georgios, why are you moving this to Ubuntu?
