the setup should ask you if this is the second host and take care of all
the right things to copy.
thanks for the pointer. The documentation at [1] describes the
required steps to setup a second node. Unfortunately it failed
for me because my second node was added to the cluster before [2].
Even manual setting the second node to "maintenance" and back
to state "up" didn't help, hosted-engine-setup as unable to
detect the host's state [3].
Though following the steps was enough to start the hosted-engine
VM manually on the second node. This makes a manual failover
possible, which is sufficient for now :)
Thanks
