Reboot an Instance

Overview

Rebooting an instance restarts the guest operating system. Xloud Compute supports two reboot types: hard reboot (equivalent to a power cycle) and soft reboot (sends an ACPI shutdown signal and restarts). Both are available as individual and batch operations.

Prerequisites

An instance in Active or Shutoff status (hard reboot) or Active status (soft reboot)
The instance must not be locked (unless you are an administrator)

Reboot Types

Type	Status Required	Behavior	Use Case
Hard Reboot	`Active` or `Shutoff`	Immediate power cycle — equivalent to pressing the reset button	Unresponsive instance, frozen OS
Soft Reboot	`Active` only	Graceful ACPI shutdown signal followed by restart	Routine restarts, applying config changes

Prefer Soft Reboot for routine restarts — it allows the OS to flush disk buffers and cleanly shut down services. Use Hard Reboot only when the instance is unresponsive to soft reboot.

Soft Reboot is not available for bare metal instances.
