Expected Behaviour
---------

VLAN network should get create

Actual Behaviour
----------

HttpException: 503, Unable to create the network. No tenant network is available for allocation

But when I try to create a VLAN network, using the command

Marking as stx.2.0 / high priority as this is a basic config.

Hi,GUPTA

Can you show your command to create the vlan network.

And maybe you can do as following steps:

#Check if the application has been re-applied successfully.
system application-list

#Check the neutron OVS agents are initialized correctly
kubectl -n openstack get pod | grep neutron

#Create a vlan network connected to the vlan datanetwork.
export OS_CLOUD=openstack_helm
ADMINID=`openstack project list | grep admin | awk '{print $2}'`

openstack network create --project ${ADMINID} --provider-network-type=vlan --provider-physical-network=${Your vlan datanetwork name} netvlan

openstack subnet create --project ${ADMINID} netvlan-subnet --network netvlan --subnet-range 192.168.103.0/24

[Akshay (yadavakshay58)]

Hi YaoLe,

1. The application is applied successfully.
2. OVS agents are up and running.
3. Still getting the same error.

[Zhang Kunpeng (zhangkunpeng)]

Maybe you need to execute these commands before creating network

Example:

ADMINID=`openstack project list | grep admin | awk '{print $2}'`
PHYSNET0='physnet0'

openstack network segment range create ${PHYSNET0}-a --network-type vlan --physical-network ${PHYSNET0} --minimum 400 --maximum 499 --private --project ${ADMINID}

[Akshay (yadavakshay58)]

Hi Zhang,

Thanks Zhang, I saw the neutron and ml2 files and I was sure that we need to create it as it is not defined in the files as we generally do while creating the OpenStack setup manually. I did it and it is working fine.

I am able to create vlan network as well only after "network segment range create". Please mention it in the document so it will be easy for people like me. Also we can define it in the ml2 file so that we need not to create it by command just to avoid these type of gaps (only a suggestion).

[YaoLe (yaole)]

This bug is an issue with steps. So this bug can be marked as invalid.

[ANIRUDH GUPTA (anyrude10)]

The bug was related to issue in steps only, but this step is not being mentioned anywhere in the Document.
Hence, it can't be considered as Invalid.
Also, the Document needs to be updated corresponding to the step that needs to be performed.

[Forrest Zhao (forrest.zhao)]

@YaoLe, please update the documentation accordingly.

[YaoLe (yaole)]

Hi, Akshay

Which is the document you have seen to setup your vlan network with wrongs.

I will check and update the documentation accordingly.

Thanks

[ANIRUDH GUPTA (anyrude10)]

Hi YaoLe,

https://docs.starlingx.io/deploy_install_guides/r2_release/virtual/aio_simplex_install_kubernetes.html

This is the link which I was following for Simplex Virtual Release 2.0

There is no reference of newtork segment range create command, due to which VLAN network was not being created.

Under section "Configure controller-0" Step 4 where we are Configuring data interfaces, this command needs to be added.

Similarly in all the variants, this command needs to be updated Under section "Configure controller-0" Step 4 where we are Configuring data interfaces. Be it in Simplex Virtual, Simplex Bare Metal, Duplex Virtual, Duplex Baremetal

[YaoLe (yaole)]

Hi, GUPTA

The docunment in
https://docs.starlingx.io/deploy_install_guides/r2_release/virtual/aio_simplex_install_kubernetes.html
is only the guide to configure data interfaces for controller-0

And the network create is the issues with OpenStack, and the docs of OpenStack
https://docs.openstack.org/ocata/networking-guide/deploy-lb-provider.html#create-initial-networks
shows the correct steps to create openstack network. Although it's not clear, but it mentioned in note that
"
To create a VLAN network instead of a flat network, change --provider:network_type flat to --provider-network-type vlan and add --provider-segment with a value referencing the VLAN ID.
"

And the clearly steps guide to setup vlan network can be seen on
https://wiki.openstack.org/wiki/StarlingX/Networking#Useful_Networking_Commands

You can follow the guide in tag:"Pass through a physical NIC to VM by binding a port with vnic_type direct_physical to the VM."
It include the steps to create vlan network.

I have get the same problem,and work fine accorss above steps,than you!
