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
- 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.

- 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
What networks need to be created additionally ?
Bridges and bonds required here or not ?
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 ?
