Hard reboot VM
Power & state
Hard reboot VM
Force an immediate power-off and restart of a virtual machine, without a graceful shutdown.
When to use
Use this only when a soft reboot (POST /api/v1/vms/{id}/reboot) does not work — for example, the VM is hung and not responding to OS-level signals.
Risks
- Unsaved data may be lost. Filesystems and applications cannot flush state before power-off.
- Filesystem corruption is possible. Hard power-off skips clean unmount.
Prefer the standard reboot whenever the VM is responsive.
