If you’re just using keepalived to manage IP addresses (i.e. you’re not using the virtual_server or lvs_sync_daemon features), it’s possible to run it under a Linode kernel by disabling LVS/IPVS features. Simply pass in the –vrrp (or -P) option on the command-line (add it to DAEMON_ARGS in /etc/default/keepalived in Debian/Ubuntu) and you’ll be good to go!

root@ubuntu:/var/log# vi /etc/default/keepalived

# Options to pass to keepalived

# DAEMON_ARGS are appended to the keepalived command-line

DAEMON_ARGS="--vrrp"
