Shutdown command stop guest graceful.
Guest os will react to a shutdown request after the the request is issued.
The differences from power off are that the guests disk storage will
be in a stable state rather than having the (virtual) power cord pulled.
Note that the guest OS may ignore the request, so the vm is not stopped.
Additionally, the hypervisor may check and support the VM 'on_poweroff'
XML setting resulting in a domain that reboots instead of shutting down.
For kimchi will not set 'on_poweroff' for VM XML configure.
So kimchi will not check the 'on_poweroff' setting of VM.
So if VM is create by other management tool and set 'on_poweroff' as
reboot, kimchi still will call this shutdown command.

results, for example unflushed disk cache in the guest.

It emulates the power reset button on a machine. Note that there is a
risk of data loss caused by reset without the guest OS shutdown.
