Hey guys,

I'm having issues installing a simple 3 node openstack setup with packstack... During Installation using packstack with a pre-written answer file I get an error complaining about "Unable to create the network. No tenant network is available for allocation." The install dose however complete and I am able to see the users, tenants and endpoints but there are no networks available and I am unable to create any...

I have provided the error message, stack trace and info about my infrastructure with my answer file below in case anyone sees anything stupid...

Thank you

Hey dbaxps,

I have posted the contents of "plugin.ini -> /etc/neutron/plugins/ml2/ml2_conf.ini"

in my /etc/neutron/ folder i do not have an ml2_conf.ini file but it seems the plugin.ini file links to the one you ml2_conf.ini links to. as for the ovs_neutron_plugin.ini dose not exist.

Thank you

I am curious if there are any errors in your neutron logs (/var/log/neutron/*.log) on your network host or on your controller relating to the failed net-create command.

larsks ( 2014-09-28 08:19:30 -0500 )edit

Hey Larsks, There is allot of noise due to the DEBUG flag being set but from a quick grep I cant see anything with net-create in it. I will search threw this more closely shortly. (currently reading links posted bellow)

Made some progress thanks to information from dbaxps above... I'm putting this as an answer as it works but I still want to work out why it was not working with GRE...

This is by no means perfect but I ended up whipping the whole thing and re-creating the answer file from scratch. This time leaving it with the VXLAN method rather then the GRE... Im not sure what the benefits/limitations of this is but at least it works for now... The only change I had to make after installing from the answer file below was to add the external interface to the Open vSwitch:

# ovs-vsctl add-port br-ex INTERFACE_NAME

The working answer file

Congratulations ! Just for fun try it (VXLAN) on CentOS 7, you will be surprised.

I'll give it a go! I'm going to be testing this config several times with different number/specs of nodes so will see what CentOS7 dose as well. Thank you for your help!! I will read up on this VXLAN stuff (thanks for the link) as well as work out why GRE failed! its bugging me! will report back

Reproduced just now with the same error at the end packstack running. Workaround with ml2_conf && plugin.ini still works as 3 months ago. I also had to update table ml2_gre_endpoints to place there correct IP addresses. Packstack doesn't generate correct plugin.ini

I have corrected my answers file in relation to what you have posted and will run it on a fresh install shortly.

I will post back with my results

Hey guys, I have the same response after changes...

I adjusted the below, please let me know if i completely missed what you were trying to tell me...

CONFIG_NEUTRON_OVS_VLAN_RANGES=physnet1 CONFIG_NOVA_NETWORK_VLAN_START=100 CONFIG_NEUTRON_OVS_TUNNEL_RANGES=1:1000

david.ward ( 2014-09-28 23:34:00 -0500 )edit

I also changed these IP ranges due to the links you showed leaving them as default as well... < CONFIG_PROVISION_DEMO_FLOATRANGE=10.100.138.0/24

CONFIG_PROVISION_DEMO_FLOATRANGE=172.24.4.224/28 < CONFIG_NOVA_NETWORK_FLOATRANGE=10.100.138.0/24 CONFIG_NOVA_NETWORK_FLOATRANGE=10.3.4.0/22

Please, try to add plugin.ini and ml2_conf.ini on Neutron node && Compute as advised . Restart boxes and see would you able to work or no. Setup has been tested on Two Node Clusters several times OK, in particular, by Kashyap Chamarthy ( RH Software ingineer).

dbaxps ( 2014-09-29 04:01:54 -0500 )edit

You might get this error during packstack, because plugin.ini -> /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini has been created manually exactly the same as ml2_conf.ini after packstack completion.
