Disclaimer:
- I am writing all this based on my 2 days of understanding of OVN setup
- So please do your own homework
- These are my notes based on how I understood
- In no way, Iam claiming that I got all of it right (hardly!)
Note:
- I am skipping the install/config part of incus as there is enough documentation out there.
- I am not using on a cluster setup yet (though that is where the real power of ovn networking is)
- I am starting with installing the ovn packages that are needed to have openvswitch on a single host
My setup:
- I have an ARM embedded board (RADXA’s Rockpi4c) running Dietpi (debian based)
- I Installed incus virtualization software platform from zabbly.com repository

Details of my host os:
host# uname -a
Linux rock4c 6.6.56-current-rockchip64 #1 SMP PREEMPT Thu Oct 10 10:50:06 UTC 2024 aarch64 GNU/Linux
host# cat /etc/os-release
PRETTY_NAME=“Debian GNU/Linux 12 (bookworm)”
NAME=“Debian GNU/Linux”
VERSION_ID=“12”
VERSION=“12 (bookworm)”
VERSION_CODENAME=bookworm

HOME_URL=“https://www.debian.org/”
SUPPORT_URL=“Debian -- User Support”
BUG_REPORT_URL=“https://bugs.debian.org/”
OVN packages installation:
host# apt install ovn-host ovn-central -y
Step 01: I ran the initial setup. I am not sure exactly what it does. Couldn’t find much details on what happens under the hood. This command is from incus documentation
host# ovs-vsctl set open_vswitch . \
external_ids:ovn-remote=unix:/run/ovn/ovnsb_db.sock \
external_ids:ovn-encap-type=geneve \
external_ids:ovn-encap-ip=127.0.0.1
Step 02: I am assigning a specific ip address of my choice (10.1.1.253) to incusbr0 bridge, replacing the original ip address assigned to it (when I did ‘incus admin init’)
host# incus network set incusbr0 ipv4.address=10.1.1.253/24
Step 03: I am seperating two different address spaces on 10.1.1.X (incusbr0 bridge) network. One address range (10.1.1.31 to 10.1.1.51) can be used for static ip address allocation for the vms and containers that connect to this network. And the other ip address range (10.1.1.131 to 10.1.1.151) is to dole them out via dhcp service onto the same network. The idea is to keep static and dhcp addresses seperately so that there will be no conflicts ( At least that is my understanding)
host# incus network set incusbr0 ipv4.ovn.ranges=10.1.1.31-10.1.1.51 ipv4.dhcp.ranges=10.1.1.131-10.1.1.151
Step 04: To test the above command, Iam launching a container
host# incus launch images:ubuntu/22.04 a1
Step 04a: I got inside the container to check its ip address
host:# incus shell a1
root@a1:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

17: eth0@if18: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000

inet6 fe80::216:3eff:fee1:a1d7/64 scope link
valid_lft forever preferred_lft forever
root@a1:~#exit
Step 04b: I see that an ip address (10.1.1.148) from the dhcp range that I set before is now being served. I now know that the dhcp address range part is working as expected
Step 04c: Iam now verifying that (from within the container) the traffic can reach incus bridge (10.1.1.253) and then to a host on the internet (zabbly.com)

All seems good with the traffic on incusbr0 bridge. Now moving onto ovn setup
Step 05a: I am creating a new network named ‘ovnnet-coke’ of type ‘ovn’
host# incus network create ovnnet-coke --type=ovn
Step 05b: I am assigning an ip address 172.16.10.153 to it (assuming that a linux bridge will be created underneath on that name. But I had a surprise. Will come to that in a bit)
host# incus network set ovnnet-coke ipv4.address=172.16.10.253/24
Step 05c: I am enabling the dhcp service on the newly created network (by setting ipv4.nat=true)
host# incus network set ovnnet-coke ipv4.nat=true
Step 05d: I am setting incusbr0 bridge to be the parent of the newly created ovnnet-coke network
host# incus network set ovnnet-coke network=incusbr0
Step 05e (optional): I believe all the above 3 commands can be combined into one command (will try it next time)
host# incus network set ovnnet-coke ipv4.address=172.16.10.253/24 ipv4.nat=true network=incusbr0
Note: Just to recap where I am right now:
- incusbr0 bridge is serving 10.1.1.X network
- ovnnet-coke is serving 172.16.10.X network
- incusbr0 bridge is the parent of ovnnet-coke
Step 05f: I am explicitly setting the incusbr0 bridge to do the routing for ovnnet-coke (172.16.10.X network)
host# incus network set incusbr0 ipv4.routes=172.16.10.0/24
Step 06: I am launching a container and connecting it to ovnnet-coke network (fingers crossed!)
host# incus launch images:ubuntu/22.04 c1 --network ovnnet-coke
Step 07: I am listing all the networks to make sure the static ip addresses that I assigned are indeed reflecting right. I believe br-int, incusovn1, incusovn1a, incusovn1b, ovs-system listed below are the ones that do the real OVN magic
host# incus network list
+-------------+----------+---------+------------------+------+-------------+---------+---------+
| NAME | TYPE | MANAGED | IPV4 | IPV6 | DESCRIPTION | USED BY | STATE |
+-------------+----------+---------+------------------+------+-------------+---------+---------+

+-------------+----------+---------+------------------+------+-------------+---------+---------+
| incusovn1b | unknown | NO | | | | 0 | |
+-------------+----------+---------+------------------+------+-------------+---------+---------+
| lo | loopback | NO | | | | 0 | |
+-------------+----------+---------+------------------+------+-------------+---------+---------+
| ovnnet-coke | ovn | YES | 172.16.10.253/24 | | | 1 | CREATED |
+-------------+----------+---------+------------------+------+-------------+---------+---------+
| ovs-system | unknown | NO | | | | 0 | |
+-------------+----------+---------+------------------+------+-------------+---------+---------+
Step 08: I am listing the instances. And Voila! The container did receive an ip address on 172.16.10.X network
host# incus ls
+------+---------+--------------------+------+-----------+-----------+
| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS |
+------+---------+--------------------+------+-----------+-----------+
| c1 | RUNNING | 172.16.10.2 (eth0) | | CONTAINER | 0 |
+------+---------+--------------------+------+-----------+-----------+
Step 09: I am checking on the bridges created underneath so far
host# ip -br -c a
lo UNKNOWN 127.0.0.1/8
eth0 UP 192.168.1.14/24
ovs-system DOWN
br-int DOWN
incusbr0 UP 10.1.1.253/24
incusovn1b@incusovn1a UP
incusovn1a@incusovn1b UP
incusovn1 DOWN
veth74dfa876@if15 UP
Step 10: My surprise! I don’t see any bridge named ovnnet-coke on the host that I created! So what it tells me is that the entire ovn networking paradigm lives within the realm of databases(s) and other constructs that incus maintains and the host OS is completely ignorant of its existence. I believe all the ovn networking magic happens outide the purvue of host os. (Hope someone can shed some light on this - if my understanding is right)
host# ip -br -4 a
lo UNKNOWN 127.0.0.1/8
eth0 UP 192.168.1.14/24
incusbr0 UP 10.1.1.253/24
host# brctl show
bridge name bridge id STP enabled interfaces
incusbr0 8000.00163eb5a19b no incusovn1a
veth48dae2d2
Step 11: The routing table on the host shows me what I was hoping to see.
- My host is on my home network 192.168.1.14
- The default router for my home network is 192.168.1.1
- All traffic on 10.1.1.X/24 network goes via incusbr0 bridge to the physical nic (eth0) on my host
- All traffic on 172.16.10.X/24 ovn network gets routed to incusbr0 bridge
- So I believe there happens a double NAT’ing. One on ovnnet-coke level and one on incusbr0 bridge level
host# ip route
default via 192.168.1.1 dev eth0 onlink
10.1.1.0/24 dev incusbr0 proto kernel scope link src 10.1.1.253
172.16.10.0/24 dev incusbr0 proto static scope link
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.14
Step 12: Finally, I got inside the newly launched container that is connected to ovnnet-coke (step 06)
host# incus shell c1
Step 13: I am listing the interfaces inside the container
root@c1:~# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo

15: eth0@if16: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000

inet 172.16.10.2/24 metric 100 brd 172.16.10.255 scope global dynamic eth0
valid_lft 2882sec preferred_lft 2882sec
inet6 fe80::216:3eff:fe68:d5c/64 scope link
valid_lft forever preferred_lft forever
Step 14a: I am able to ping the ip address that I assigned (step 05b) while creating ovnnet-coke
root@c1:~# ping 172.16.10.253
PING 172.16.10.253 (172.16.10.253) 56(84) bytes of data.

^C
— 172.16.10.253 ping statistics —
3 packets transmitted, 3 received, 0% packet loss, time 2004ms
rtt min/avg/max/mdev = 2.769/2.942/3.284/0.241 ms
Step 14b: I am able to ping the ip address of the incusbr0 bridge as well (step 02)
root@c1:~# ping 10.1.1.253
PING 10.1.1.253 (10.1.1.253) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.449/1.828/4.580/1.945 ms
Step 14c: Finally I am able to ping an external host on the internet (zabbly.com)
root@c1:~# ping zabbly.com

rtt min/avg/max/mdev = 79.559/85.093/96.137/7.809 ms
Step 14d: I installed traceroute package to verify the traffic path from the container running on ovnnet-coke to all the way to zabbly.com. Worked like charm!
