Install QlikView Server on both hosts.
In each host go to Services and
Start QVS and QVWS on one server.
Start QDS on the other server.
** do not start multiple QVS and QDS unless you have clustered or multiple licenses.
You'll also need to start DSC and QMC services on one of those hosts; your choice which one.
Go to the QMC -> System and update the configurations.
