As of podman 4, we can make use of a network stack based on Netavark and Aardvark instead of former CNI:
https://www.redhat.com/sysadmin/podman-new-network-stack
https://blog.podman.io/2023/04/lease-dynamic-ips-with-netavark/

Danish Prakash has compiled some information about how this new network backend can be tested:
https://confluence.suse.com/display/~danishprakash/Podman+Networking+Features+to+Test

Packages to be installed:

zypper in netavark aardvark-dns

To do so, /etc/containers/containers.conf needs to be changed to:

[Network]
network_backend="netavark"

and it's possible to check which network stack it's using:

podman info --format {{.Host.NetworkBackend}}

(by default it should be cni)

We don't need to implement new tests with this, but do the change and then run podman network tests.

Affected versions:

• 15-SP3
• 15-SP4
• 15-SP5
• Tumbleweed
• Leap 15.4
• Leap 15.3

Acceptance criteria¶

• Extend podman_network.pm test module to switch the backend and run all the tests.
• Use https://confluence.suse.com/display/~danishprakash/Podman+Networking+Features+to+Test as a base
• Enable this only for podman > 4.4.2
