No sleep options on Hyper-V

I installed 2 machines on Hyper-V and none of them have the Sleep options under "Power Options". Is there a fix?
Thanks

Try disabling "dynamic memory" for your VM. I know for a fact that this prevents hibernation from working, but am only guessing that this may affect sleep as well.

Let me know that helps.

Do you have a specific need to have sleep available in a VM, or is your question just out of curiosity? If you just want to suspend its activity, then 'restore down' to have the VM connection in a window on your host machine. Then Pause is available in the Action menu and on the toolbar.





If you specifically need sleep/hibernate for test purposes then no, neither sleep or hibernation are available to the guest OS in a Hyper-V VM. It is possible to enable hibernation for a Hyper-V VM though....

Sleep is probably not possible, even on a physical machine it requires a video driver that supports Standby (S3). It's unlikely that the 'Microsoft Hyper-V Video' HyperVideo.sys driver does.

thank you, I guess that's the reason, the Hyper-V Video driver does not support S3.
I need to disable sleep, that's why I asked (not just curiosity )

So I'm not sure now if there's not sleep option, does it never sleep or it will sleep whenever?

Thank you!
