Has anyone been successful with configuring real server VIP addresses (lo:0) on Ubuntu 18.04?
Previously, I configured the loopback address in /etc/network/interfaces like this: auto lo:0 iface lo:0 inet static address 12.34.56.78 netmask 255.255.255.255 pre-up sysctl -q -p On 18.04, I tried adding this section to the netplan config: network: ethernets: lo: addresses: - 12.34.56.78/32 And then ran netplan apply. systemd-networkd logs the following: May 18 10:01:55 [...] systemd-networkd[3820]: lo: Adding address: 12.34.56.78/32 (valid forever) May 18 10:01:55 [...] systemd-networkd[3820]: lo: Adding address: 127.0.0.1/8 (valid forever) May 18 10:01:55 [...] systemd-networkd[3820]: rtnl: received address with invalid family 129, ignoring But it doesn't seem to have any effect (ifconfig doesn't list lo:0). Not sure what the invalid family 129 refers to. The actual address (it's not 12.34.56.78 :-) ) works fine when I manually use ifconfig to set it up. I also tried using lo:0 as the YAML key name, but then I get this error: May 18 10:00:06 [...] systemd-networkd[3736]: /run/systemd/network/10-netplan-lo:0.network:2: Interface name is not valid or too long, ignoring assignment: (null) Looks like systemd-networkd doesn't like lo:0 as an interface name. Any suggestions?
