Sleep/Hibernate on virtual machines

Hi,

I know that the sleep/hibernate is disabled on the host if Hyper-V is installed and we need to remove Hyper-V in order to re-activate it, but what about the Virtual Machines that are running inside Hyper-V? Why can't I enable it and make some test?

I installed a Windows 10 Home on a virtual machine running on Windows Server 2012 but I'm not able to find any option to put it to sleep or hibernate it.

Thank you in advance :)
