Error: netavark: failed configure macvlan: IO error: failed to add route: Invalid argument (os error 22)
9:53 a.m.
Hello,
I would like to create rootful containers with static IPv4 and IPv6
addresses that are part of my network (containers that somehow act as
physical devices on my network).
From what I understand in the documentation [1], the macvlan driver
should be my preferred option with netavark.

https://github.com/containers/podman/blob/main/docs/tutorials/basic_netwo...
My problem is that I get an error when starting a container attached to
a macvlan network created with an IPv6 subnet:
Error: netavark: failed configure macvlan: IO error: failed to add
route: Invalid argument (os error 22)
FYI, as long as the maclan network is created without IPv6 subnet, I can
create new podman containers without error.

Hi Laurent,
Why are you using fe80::/112 as a subnet? This is a link-local address
which has a special meaning for ipv6, you should not use this address space
and I don't expect this to work.
If you use podman network create --ipv6 it will create a random private
ipv6 subnet for you.

Hi Paul,
I thought that the link-local addresses was the IPv6 equivalent of IPv4
private addresses (10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16), but I
was wrong :)
It seems that I was looking for the IPv6 "Unique local addresses"
(fc00::/7). Using this subnet with "podman network create" and "podman
run" did what I expected and I'll now use this subnet for my tests.
In the end, each container will have a public routable IPv6 address.
Thanks.
