The enum defines values that indicate whether or not the virtual machine should be powered off if a host determines that it is isolated from the rest of the cluster.
NONE : Do not power off the virtual machine in the event of a host network isolation.
POWER_OFF : Power off the virtual machine in the event of a host network isolation.
SHUTDOWN : Shut down the virtual machine guest operating system in the event of a host network isolation. If the guest operating system fails to shutdown within five minutes, HA will initiate a forced power off. When you use the shutdown isolation response, failover can take longer (compared to the response) because the virtual machine cannot fail over until it is shutdown.
CLUSTER_ISOLATION_RESPONSE : Use the default isolation response defined for the cluster that contains this virtual machine.
Enumeration: NONE, POWER_OFF, SHUTDOWN, CLUSTER_ISOLATION_RESPONSE,
