If set to disabled, then HA is disabled for this virtual machine.

If set to high, then virtual machine with this priority have a higher chance of powering on after a failure, when there is insufficient capacity on hosts to meet all virtual machine needs.

If set to medium, then virtual machine with this priority have an intermediate chance of powering on after a failure, when there is insufficient capacity on hosts to meet all virtual machine needs.

If set to low, then virtual machine with this priority have a lower chance of powering on after a failure, when there is insufficient capacity on hosts to meet all virtual machine needs.

Default: 30

ha_vm_max_failure_window

integer

The number of seconds for the window during which up to ha_vm_max_failures resets can occur before automated responses stop.

Valid only when ha_vm_monitoring=vmAndAppMonitoring or ha_vm_monitoring=vmMonitoringOnly.

Unit is seconds.

Default specifies no failure window.

Default: -1

ha_vm_max_failures

Valid only when ha_vm_monitoring=vmAndAppMonitoring or ha_vm_monitoring=vmMonitoringOnly.

Unit is seconds.

Default: 120

ha_vm_monitoring

string

State of virtual machine health monitoring service.

If set to vmAndAppMonitoring, HA response to both virtual machine and application heartbeat failure.

If set to vmMonitoringDisabled, virtual machine health monitoring is disabled.

If set to vmMonitoringOnly, HA response to virtual machine heartbeat failure.

If enable=false, then this value is ignored.

Choices:

  • "vmAndAppMonitoring"

  • "vmMonitoringOnly"

  • "vmMonitoringDisabled" ← (default)

host_isolation_response

string

Indicates whether or VMs should be powered off if a host determines that it is isolated from the rest of the compute resource.

If set to none, do not power off VMs in the event of a host network isolation.

auto_compute_percentages

boolean

By default, reservation_based_admission_control.failover_level is used to calculate reservation_based_admission_control.cpu_failover_resources_percent and reservation_based_admission_control.memory_failover_resources_percent.

Notes

Note

  • All modules requires API write access and hence is not supported on a free ESXi license.

  • All variables and VMware object names are case sensitive.
