Bug description:
  Configure netplan for interfaces, for example (a working config with
  IP addresses obfuscated)

  network:
      ethernets:
          eth0:
              addresses: [192.168.0.5/24]

phone.blah.com]

  Configure keepalived (again, a working config with IP addresses
  obfuscated)

          virtual_ipaddress {
                  10.22.14.3/24
          }
  }

  At boot the affected interfaces have:

  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 
default qlen 1000
      link/ether ab:cd:ef:90:c0:e3 brd ff:ff:ff:ff:ff:ff

      inet6 fe80::ae1f:6bff:fe90:c0e3/64 scope link 
         valid_lft forever preferred_lft forever
  7: eth3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group
