Hello dear!


If a VM fails, HA builds a new VM.

Hope this helps!

Hello, when the system detects that the VM is in ERROR state (corresponding to the vm_state field, the VM HA is triggered.) The VM state changes to ERROR because of a service operation or exception. Alternatively, the ACTIVE state and the SHUTDOWN power state (corresponding to the power_state field) trigger the VM HA.
I hope my answer will help you.

The VM HA feature ensures quick recovery of a VM. With this feature, when a VM is faulty, the system automatically re-creates the VM on another normal compute node.

When detecting a VM fault, the system selects a normal compute node to create the faulty VM on the normal compute node.

Restart or restoration of a compute node from a power failure
When a compute node restarts or recovers from a power outage, the system re-creates the HA VMs running on this node on other compute nodes.

VM BSOD (x86 architecture)
When detecting that BSOD occurs on a VM and the handling policy configured for this error is HA, the system re-creates the VM on another normal compute node.
