force source ip

I tried the right click and: Shutdown, Reboot, Stop and none of them actually do anything. I just fire up the console for the node and do "shutdown -r now" which seems like a gigantic sledge hammer... So what is the best practice to actually forcibly, "turn off" a VM?

An ancient container I inherited in a /25 at location 1 with ip Q on host Z needs to be moved to location 2 on host Y and retain ip Q. We cannot move the /25, there are other hosts+vms+cts on it at 1. We can only route Q/32 to Y. The CT's software cannot be touched or reconfigured or otherwise...
