HA
Nova-network VLAN Manager

Steps to reproduce:
1. Create a cluster with QEMU as a hypervisor and Legacy Networking (nova-network)
2. Add 3 nodes with roles - 3 controller
3. Add 1 node with role compute,cinder
4. Set Nova-Network VlanManager as a network backend and Fixed network size-8(example), Number of fixed networks-3(example)
5.Deploy the cluster
6.Run instatnce.

Nova-network create interfaces with gateway, dhcp_start,etc NOT from the DB nova (table networks).

If manualy change settings multi_host = False(/etc/nova/nova.conf) and restart nova-network, nova-network will be used data(gateway, dhcp_start,etc) from the DB nova(table networks).

I'm sorry, but the description is rather confusing. Alexander, could you please elaborate what exactly is a problem here?

1) multihost does not work properly?
2) network specific settings are ignored? (dhcp_start, gateway)
3) etc?

2) network specific settings are ignored (dhcp_start, gateway)

Hello, Alex. We can't fully understand the problem by your description. Could you please describe the steps carefully after creating the environment and write in what way the behavior is wrong and what it is expected to be?

[Alexander Arzhanov (aarzhanov)]

Pavel, I'm update bug description...

[Pavel Kholkin (pkholkin)]

Regarding ips given to vms, when multihost=true 'gateway' values of the vms are equal to gateways of the compute nodes and vm ips could not be consecutive, https://www.mirantis.com/blog/openstack-networking-vlanmanager/.
Do you have any other concerns about the bug?

[Alexander Arzhanov (aarzhanov)]

I can’t reproduce this bug on iso 6.1-338(for example), nova-network work fine.

Alexander, great, thank you. I am moving the bug to invalid. Feel free to reopen it if the issue reoccurs.
