Is there any difference between performing an OpenStack soft reboot instance through the web interface Horizon and SSH into the instance and perform sudo reboot?

OpenStack Dashboard Server Reboot
Use this function to perform either a soft or hard reboot of a server. With a soft reboot, the operating system is signaled to restart, which allows for a graceful shutdown of all processes. A hard reboot is the equivalent of power cycling the server. The virtualization platform should ensure that the reboot action has completed successfully even in cases in which the underlying domain/VM is paused or halted/stopped.
Nova Server Reboot
OpenStack soft reboot:
$ nova reboot INSTANCEOpenStack hard reboot:
$ nova reboot --hard INSTANCE
Server Reboot
If you perform sudo reboot OpenStack will not know whether the reboot was intentional...
