What happens to the VMs on a node when a PDU failure occurs in a Nutanix cluster?

The VMs are permanently lost
The VMs restart automatically
The VMs remain powered on
The VMs go into a migration state

The correct answer is: The VMs restart automatically

When a Power Distribution Unit (PDU) failure occurs in a Nutanix cluster, the VMs on the affected node typically restart automatically. This behavior is due to the cluster’s ability to manage resources and ensure high availability. When a node loses power or becomes unreachable due to a PDU failure, the hypervisor detects the loss and initiates a failover process. The virtual machines running on that particular node are then automatically restarted on other available nodes within the cluster. The infrastructure is designed to minimize downtime and ensure that applications remain available even in the event of hardware-related issues. This automatic restart of VMs helps maintain continuity of service and is a critical feature of Nutanix’s architecture that enhances resilience in a virtualized environment.
