I am currently looking into High Availability for my work setup. I am having some problems understanding how to achive that. I have two servers, one running libvirt and a couple VM, the other one nothing much yet.

To achieve HA with keepalived, I would have to setup the exact same VMs under the second server, right? If that's the case, how would I make sure that the "mirrors" stay equal, If for example the master goes down, the backup takes over, some changes are made in a DB and the master knows nothing about these changes.

Maybe I misunderstood keepalived so far, can somebody provide me with an example setup or hints on how to achieve what I want to do?

Kind Regards

g7s
