If the application running on the VMs is a 'legacy' application (say something like a database server) and not an application you developed from scratch, then you should setup your virtual machines like you would setup 'real' hardware. This is a very common question that is debated at will and doesn't have a clear answer though because it's too generic.

You should specify exactly your setup and applications you want to run on the VMs or this question will be closed as too generic (and discussion will be asked to move on a mailing list where this topic regularly comes up).

You can do some of that with CoreOS and Docker:


If you want to use full VM's for that, look into corosync and pacemaker:
