I am running Windows Media Player within a Windows XP VM to watch DRM-protected videos. Host is a Mac running Mountain Lion. Windows does not go to sleep as WMP naturally prevents it. However, after a while, the Mac's screen goes dim and eventually the Mac would go to sleep.
Is there a way to:
- tell VirtualBox to pass the sleep prevention from the guest to the host?
- tell VirtualBox to prevent the host to sleep for this particular VM?
- tell VirtualBox to prevent the host to sleep when a VM is running?
So far, the only solution I found (beyond moving the mouse during the video) is to change the sleep settings on the Mac. But this is very inconvenient as I want them back whenever I do something else on this computer. After searching this forum and elsewhere on the web, I did this:
- Code: Select all Expand viewCollapse view
VBoxManage setextradata WindowsXP VBoxInternal/Devices/acpi/0/Config/PowerS1Enabled 1
But I believe this is unrelated or the other way around.
