Description

Motivation

See #134282 . So far we always relied on the installation to use the "hypervisor role" hence enabling persistent IP forwarding but we never ensured IP forwarding to be properly enabled by https://gitlab.suse.de/openqa/salt-states-openqa/ until https://gitlab.suse.de/openqa/salt-states-openqa/-/merge_requests/987 . We still don't know for sure if that is enough or correct.

Apparently it's not enough. See #135407-27 and the according MR. The changes in trusted.xml are not enabling forwarding on all interfaces. It's only known to be enabled when something or someone else did.

The already applied salt rules seem to work fine:

salt -C 'G@roles:worker' cmd.run 'grep forward /etc/sysctl.d/99-salt.conf'
openqaworker17.qa.suse.cz:
    net.ipv4.ip_forward = 1
    net.ipv4.conf.br1.forwarding = 1
    net.ipv4.conf.eth0.forwarding = 1
[...]
salt -C 'G@roles:worker' cmd.run 'sysctl net.ipv4.ip_forward'
openqaworker16.qa.suse.cz:
    net.ipv4.ip_forward = 1
openqaworker17.qa.suse.cz:
    net.ipv4.ip_forward = 1
openqaworker18.qa.suse.cz:
    net.ipv4.ip_forward = 1
