[fedora-virt] Disable screen powerdown on vms

[Thomas S Hatch]

On a regular redhat/fedora system booting into runlevel 3, the screen shuts
down after a few minutes of being idle.  I have some finicky clients, and
when they open up a console to a vm they get scared (still) when it is all
black.  Where is the setting to prevent the vm from trying to powersave a
non-existent screen?
