Sebastian,
From what you are describing check what the shutdown and reboot command are
trying to do. If they are trying to send a "ctl-alt-del" sequence and the
screen is locked I would expect Windows to basically ignore them. I would try
this:
1) On the VNC screen do a "ctrl-shift-alt-2" and get to the QEMU command
screen.
2) Then enter the command "system_powerdown" to see if the system does a
shutdown.
I am running a older version of qemuu but the command screen should be
basically the same. The sequence "ctrl-shift-alt-1" should put you back on the
Windows-10 console screen.
The attached script rc.vms is something I wrote to start and stop virtual
machines on my Slackware Linux system. It uses the qmp port to send commands
to qemu. It might help. When I start the VMs on the systems running VMs I
have the command argument:
-qmp unix:/tmp/.qemu_control_XXXXX,server,nowait
added, where XXXXX is a port number. The rc.vms script uses this to talk to
the qemu command interface. The file /etc/virtual_machines/qemu_vm.conf
contains command to start the VMs. The commands in the file are like this:
/vms/Network/DNS_Server_1/VM_Start.sh
sleep 60
/opt/laster/sbin/listvms
sleep 10
The attached script listvms is used to list the VMs that are running. The
scripts VM_Start.sh are used to configure and start the VMs. I also use the QMP
command.
