How do I create nova networks for Folsom on Ubuntu 12.04?

http://docs.openstack.org/trunk/openstack-compute/install/apt/content/ap_installingfolsomubuntuprecise.html

The guide uses nova-network for folsom on 12.04.

http://docs.openstack.org/trunk/openstack-compute/install/apt/content/ap_installingfolsomubuntuprecise.html is Appendix B from the instructions at http://docs.openstack.org/trunk/openstack-compute/install/apt/content/.

These were the first set of instructions I followed.

When I try and create a network, I get the following error

$ nova-manage network create private --fixed_range_v4=192.168.30.0/24 --num_networks=1 --bridge=br100 --bridge_interface=eth0 --network_size=256
Command failed, please check log for more info

Or

$ nova-manage network create private --fixed_range_v4=192.168.30.0/27 --num_networks=1 --bridge=br100 --bridge_interface=eth0 --network_size=32
Command failed, please check log for more info

I have working Diablo and Essex compute installs, which use nova.network.manager.FlatDHCPManager when using a bridge.

The nova.conf in these instructions uses network_manager=nova.network.manager.VlanManager

Also br100 was not setup in the install instructions and is not set in the nova.conf

I cannot create a network using the Folsom Ubuntu install instructions, but I don know openstack engough to understand why.

The problem seems very simialr to the bugs I listed in my original question.

I have included my nova.conf and network config for reference:

hi,
i do have a same problem pls inform me if u find the solution for this pls i need it..

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

I still think there is a bug or a problem with the instructions.

I have not solved this problem.

http://docs.openstack.org/trunk/openstack-compute/install/apt/content/ap_installingfolsomubuntuprecise.html

Does this not solve your issue David.

Koolhead17,

I followed tha Appendix B, almost all of it worked without problems, except when I try and create a network using

$ nova-manage network create private --fixed_range_v4=192.168.30.0/24 --num_networks=1 --bridge=br100 --bridge_interface=eth1 --network_size=256
Command failed, please check log for more info
2012-10-25 10:54:06 CRITICAL nova [req-d30f31cc-0c73-4ec5-85df-52963d4f6c5c None None] 'vlan_start'

This means I cannot create a network and run a VM.

Dave.

Hi,

i'm also using the same manual but i user FlatDhcp Manager instaed of vlan manager it works for me may be u can try with that..

regards,
Vignesh

Vignesh,

Thanks for the advice. Writing a paper at moment, but will try.

Did you need to manually configure a bridge interface (br100) in /etc/network/interfaces ?

Did you need to change any other nova.conf network settings from Appendix B beside the network_manage?
e.g. public_interface, vlan_interface, flat_network_bridge, flat_interface

Which of the nova-manage network create private commands did you use?

Thanks in advance.

Dave.

Hi Dave,

http://www.hastexo.com/resources/docs/installing-openstack-essex-4-ubuntu-1204-precise-pangolin/step-5-install-and-configur

This is the link which has configuaration regarding dhcpmanager. Try it if u have any problem please let me know....

regards,
Vignesh

Hi David,

Its seems like nothing is wrong with your nova.conf

try the following command

$ sudo nova-manage network create private --fixed_range_v4=192.168.30.0/24 --num_networks=1 --bridge=br100 --bridge_interface=eth0 --network_size=256

i changed the value of this command as per your configuration file, try this...

DON'T FORGET TO INCLUDE SUDO IN THE BEGINNING OF THE COMMAND

let me know its working or not..

Regards,
Rajesh kannan
