Guest configuration issue. The Xorg server uses very conservative
defaults for the monitor capabilities, you need to change these to
get higher resolutions.
Drop the following into /etc/X11/xorg.conf.d/monitor.conf and you are set.

Valid values for type are cirrus Cirrus Logic GD5446 Video card. All Windows versions starting from Windows 95 should recognize and use this graphic card. For optimal performances, use 16 bit color depth in the guest and the host OS. (This one is the default) std Standard VGA card with Bochs VBE extensions. If your guest OS supports the VESA 2.0 VBE extensions (e.g. Windows XP) and if you want to use high resolution modes (>= 1280x1024x16) then you should use this option. Additional info: windows server 2012r2 also hit this problem, win7-64 guest not hit this problem.
