qm reboot [options] vmid

qm reboot reboots a virtual machine by shutting it down gracefully and starting it again. Pending configuration changes are applied during the restart.
The timeout option limits how long to wait for the graceful shutdown before forcing a restart.

--timeout seconds

Maximum time to wait for shutdown before forcing restart

Requires ACPI support in the guest OS for graceful shutdown. If guest doesn't respond within timeout, the VM may be forcefully stopped.
