Let a Virtualbox guest wake up from Suspend

Question

I prefer to try stuff in a VirtualBox guest before I do it on a physical machine.

In a Linux (Arch Linux to be specific) guest I put the system in suspend mode either by issuing

systemctl suspend

Or from the host system (my machine is named Arch) by

VBoxManage.exe controlvm Arch acpisleepbutton

Something happens, I guess it works. The screen goes blank except for a static (non blinking) cursor in the upper left corner.

How do I exit suspend mode? Just typing keys and moving the mouse does not seem to be enough. I looked around but could not find a way to do it from the GUI or VBoxManage. Is there a way?

Answer 1

You can send ACPI shutdown with Host + H on Windows. Despite the signal name it won't shutdown the guest, it will just wake him up.
