When memory hotplug is enabled you can't downgrade memory properly for that VM. I know it's not possible to hot unplug/downgrade the memory, but when the VM is running and you downgrade the memory the new memory config should be highlighted red and will be active when you stop/start the VM. This works OK when memory hotplug is disabled, but when memory hotplug is enabled a downgrade will run very long and then gives the following error:

Code:
Parameter verification failed. (400)

memory: hotplug problem - 400 Parameter verification failed. dimm2: error unplug memory module

In spite of the error the new amount of memory is highlighted in red, so in fact it works. But it takes very long and the error is also not very nice. Maybe this can be fixed in a future released?
