Is Sleep or Hibernate possible in Windows guest VM?

[kingp0dd]

Sleep option is not present in the Start menu. This VM is for veeam and I'd like to put it to sleep when not performing a backup (it has an option to go to Sleep after a backup completes). I have a task to wake it up on schedule but when I'm going to test it, I found out that Sleep is not present in Start Menu. I also tried

rundll32.exe powrprof.dll,SetSuspendState 0,1,0

but it's not working too.

Is there an option in Proxmox to allow Sleep?

udpate: it says Graphics, my Graphics in VM options is just set to Default. Is it related to that? Do I need to change it to something else for Sleep to work?

powercfg /availablesleepstates
The following sleep states are available on this system:
Hibernate
Fast Startup

The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.
An internal system component has disabled this standby state.
Graphics

Standby (S2)
The system firmware does not support this standby state.
An internal system component has disabled this standby state.
Graphics

Standby (S3)
An internal system component has disabled this standby state.
Graphics

Standby (Connected)
The system firmware does not support this standby state.

Hybrid Sleep
Standby (S3) is not available.

There are probably several solutions thinkable.

I would simply shutdown the VM from inside the guest and start the VM via cron "qm start <vmid>" on the host. This just look more "normal" to me...

Good luck.
