I think that there is some confusion here so I will explain what are the configurations for fail-over.
power management will reboot your host if a connectivity issue is detected so all your vm's will be killed. resilience policy will allow you to choose vm migration policy during a host failure and its configured in the cluster level (clusters -> select cluster -> general sub tab -> edit policy) High Availability is configured only for servers type vm's and what it does is re-run the vm in case the pid of the vm is killed (so most commonly, if you have power management configured, and the host is rebooted, the vm will start automatically on a different host).
so it really depends what you want. if you want vm migration than look into cluster policy, if you want a specific vm to always be up and you don't care about the other vm's than configure power management and a HA vm. it really depends on what you need.

Hi,
You have to configure power management to make high availability working and mark the vms high availability checkbox...

What should I need to configure to put HA working? I mean, when a host broke all the VM automatically move to another host. Do I need to have Power management enabled?
