How can I add more than one VM if overloading in CloudSim Plus?
I am trying to do horizontal auto-scaling in the CloudSim Plus simulator. I need to scale up the application by more than one VM. I am trying to modify the example LoadBalancerByHorizontalVmScalingExample provided by CloudSim Plus.
The example has a setVmSupplier() function which has a createVm() parameter which returns only one VM. Moreover, the setVmSupplier() function accepts only one VM and not a list of VMs. I am not able to modify the function even in the superclass. How can I provide more than one VM?

You don't have to make the VmSupplier return a list of VMs.
If you need that more than one VM is created, you just need to ensure
the isVmOverloaded method in the mentioned example contains a condition that will remain true after being called in different times.
If at the time the VM is checked it is still overloaded, the HorizontalVmScaling object will call the VmSupplier function to create a new VM. This is how you ensure that multiple VMs are created to balance the load.
