Removing charm-keepalived since I believe no changes are needed there. It should pick up fixes once they are available on apt archives.

Pacemaker is smarter in this case because it has a service monitor that will restart the virtual IP resource, in affected node & nic, before considering a real failure, but other HA service might consider a real failure when it is not. [test case] - comment #14 is a full test case: to have 3 node pacemaker, in that example, and cause a networkd service restart: it will trigger a failure for the virtual IP resource monitor. - other example is given in the original description for keepalived. both suffer from the same issue (and other HA softwares as well). [regression potential] - this backports KeepConfiguration parameter, which adds some significant complexity to networkd's configuration and behavior, which could lead to regressions in correctly configuring the network at networkd start, or incorrectly maintaining configuration at networkd restart, or losing network state at networkd stop. - Any regressions are most likely to occur during networkd start, restart, or stop, and most likely to involve missing or incorrect ip address(es). - the change is based in upstream patches adding the exact feature we needed to fix this issue & it will be integrated with a netplan change to add the needed stanza to systemd nic configuration file (KeepConfiguration=) [other info] original description: --- Configure netplan for interfaces, for example (a working config with IP addresses obfuscated) network: ethernets: eth0: addresses: [192.168.0.5/24] dhcp4: false nameservers: search: [blah.com, other.blah.com, hq.blah.com, cust.blah.com, phone.blah.com] addresses: [10.22.11.1] eth2: addresses: -
