To check this feature is working as expected, one can use Rails console:

# vmdb
# rails c
irb> $evm = MiqAeMethodService::MiqAeService.new(MiqAeEngine::MiqAeWorkspaceRuntime.new)

For example, you want to change the CPU and memory of a VM named 'test_vm'. Here are the command to execute in Rails console:

irb> vm = $evm.vmdb(:vm).find_by(:name => 'test_vm')
irb> vm.set_number_of_cpus(2)
irb> vm.set_memory(4096)

Then, you should see in your RHV environment that VM named 'test_vm' has 2 vCPUs and 4 GB of memory.

I followed steps in Comment 6 and  I was able to change the VM memory and number of cpus.
