Hey, One very important question right away: what network driver are you using? Is it OVS or OVN? If you're just relying on defaults and don't really know, then what version of OSA you're using? As based on the choice of network driver following configuration and advices would be different. On Sat, Aug 19, 2023, 00:54 Murilo Morais <murilo@evocorp.com.br> wrote:
Good evening everyone!
When using Tenant Network I can't make the instances communicate when they are on different hosts, I believe I'm forgetting to configure something related to network_hosts, but I'm not sure what. It wasn't clear to me exactly the difference between "network_hosts", "network-infra_hosts" and "network-agent_hosts".
I'm using the following configuration: openstack_user_config.yml: cidr_networks: container: ... storage: ...
used_ips: [...]
global_overrides: internal_lb_vip_address: ... external_lb_vip_address: ...
management_bridge: br-mgmt no_containers: false provider_networks: - network: container_bridge: br-mgmt container_interface: eth1 container_type: veth ip_from_q: container is_container_address: true type: raw group_binds: - all_containers - hosts
- network: container_bridge: br-provider container_type: veth type: vlan range: "100:200" network_interface: "eno2" net_name: vlan group_binds: - neutron_openvswitch_agent

Example to upload the instances: network create network_test subnet create --network network_test --subnet-range 192.168.0.0/24 subnet_test server create --flavor m1.large --image debian-11-genericcloud-amd64-20230601-1398 --network network_test --key-name my_key --use-config-drive debian_test1 server create --flavor m1.large --image debian-11-genericcloud-amd64-20230601-1398 --network network_test --key-name my_key --use-config-drive debian_test2
If for some reason any of them go up on different hosts, even configuring the IP manually, they don't communicate, but the instant they are on the same host the ping starts to work.
