Hi, Check out this page: https://docs.openstack.org/kolla-ansible/latest/reference/networking/neutron... You need some sort of external network to provide connectivity for instances. Zitat von KK CHN <kkchn.in@gmail.com>:

List,

I am a bit confused with the OpenStack Networking configuration for Created virtual machines on a (Kolla-ansible all-in-one on an Ubuntu 22.04 VM ) openstack installation.

I am able to create virtual machines through the dashboard as well as CLI. I have used the default network/cirros images created from init-runonce script.

But Real time, how can I configure these new VMs to communicate with Base VM or external world by ping, ssh or make internet connection etc.

Base VM is Ubuntu22.04 - with IPs ens192=>10.170.16.128(with Internet), second interface => ens224 => 10.220.0.51 and ens160 up and running without IP address for neutron_external_interface:

All the VMs which I created getting IP addresses in series (10.0.0.X).

But How to allocate Internet and make external world communication to and from these VMs ?

Any hints/directions towards this much appreciated.

Greetings, Krish

If required more inputs here follows the additional information.

Additional inputs:

There are 3 virtual interfaces on the base Ubuntu22.04 Virtual Machine. ens192->10.170.16.128 with internet, ens224->10.220.0.51 , ens160 up without IP

1. First Interface contain IP address from My organizations DHCP lease from LAN(10.16.16.0) Which has Internet connectivity. ens192: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:0c:29:33:18:3c brd ff:ff:ff:ff:ff:ff altname enp11s0 inet 10.170.16.128/23 brd 10.170.17.255 scope global dynamic noprefixroute ens192 valid_lft 786963sec preferred_lft 786963sec inet6 fe80::cd1a:bc6c:b129:f91f/64 scope link noprefixroute valid_lft forever preferred_lft forever3

2. Interface I have 10.220.0.51

ens224: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 00:0c:29:33:18:46 brd ff:ff:ff:ff:ff:ff altname enp19s0 inet 10.220.0.51/24 brd 10.220.0.255 scope global noprefixroute ens224 valid_lft forever preferred_lft forever inet 10.220.0.24/32 scope global ens224 valid_lft forever preferred_lft forever inet6 fe80::a8b6:f094:c47:8282/64 scope link noprefixroute valid_lft forever preferred_lft forever

3. ens160 without any IP address which is up and running configured for Kolla neutron_external_interface: "ens160"

ens160: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq master ovs-system state UP group default qlen 1000 link/ether 00:0c:29:33:18:32 brd ff:ff:ff:ff:ff:ff altname enp3s0

1. What networks need to be created additionally ? 2. Bridges and bonds required here or not ?

3. To enable these New VMs to talk to external world( ssh, ping, internet connection to all these VMs ) what all the steps need to be performed or I left out ?
