Description of problem:
The latest kernel supports KMS (Kernel Mode Setting) in virtual machines, but it's setting a very large resolution -- 1280x1024 -- and the display doesn't fit on my physical monitor -- 1680x1050 -- when you account for the title bar and menu bar and tool bar on the virt-viewer window.  I either have to scale the display (which looks ugly) or scroll around a lot.

This was particularly problematic yesterday when testing the Anaconda text mode for the Fedora 19 Test Days.

I found a workaround by adding
    drm_kms_helper.edid_firmware=edid/1024x768.bin
to the kernel command line options to force 1024x768, but it would be nice if this happened automatically, or if there was a way to select the virtual screen size in the machine settings.

Version-Release number of selected component (if applicable):
libvirt-1.0.5.1-1.fc19.x86_64
qemu-kvm-1.4.1-3.fc19.x86_64
virt-manager-0.10.0-0.4.gitb68faac8.fc19.noarch
kernel-3.9.3-301.fc19.x86_64

How reproducible:
every time

Steps to Reproduce:
1. install Fedora 19 to a virtual machine in text mode

Actual results:
virtual screen is set to 1280x1024 which doesn't fit (or just barely fits) on most monitors with a height of 1050 or 1080, and certainly doesn't fit on smaller screens

Expected results:
start with a lower resolution, or allow a way to easily select a resolution for the virtual machine
