virtualization – Mac Virtual Machine can’t sleep

I have been running a macOS Ventura virtual machine using both UTM and Parallels on a Ventura host and have been trying to put the VM to sleep so I can monitor what happens with the logs. However, it seems that the virtual machine is unable to go to sleep.

Pressing Sleep from the menu bar has no effect and pmset sleepnow returns Unable to sleep system: error 0xe00002e2. I have tried setting sudo pmset -a disablesleep 0 but that doesn’t work. Additionally, when I type pmset -g some settings appear to be missing even though I have set them and they are present in com.apple.PowerManagement.plist – namely hibernatemode and hibernatefile. I have also noticed that pmset -g uuid returns (NULL)`.

Would anyone know how I could get the virtual machine to sleep? Maybe I need to change some boot arguments?
