I want to implement active/standby arrangement between 2 internal loadbalancer VMs (haproxy on each) via keepalived. These loadbalancers are supposed to expose a private ip for use by other programs internal to my VPC. How do I assign a virtual ip address to these nodes?
When I attempted to assign the same private ip address to the primary NICs of both nodes, I got an error message about a conflict when configuring the 2nd node.
