Public bug reported:
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:
- 12.13.14.18/29
- 12.13.14.19/29

Run 'netplan try' (didn't even make any changes to the configuration) and the
keepalived addresses disappear never to return, the affected interfaces have:
5: eth4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group
