[CentOS] Console access to kvm guest running WindowsV7

i86_64 CentOS-6.5

I have installed a Windows instance as a kvm guest on a host running CentOS-6.5. I can access the desktop through the virt-manager console and everythign seems to work, although the mouse cursor seems to get lost from time to time.

The virt-manager console display supports various resolutions but when I re-size the desktop display remains essentially a square inside a letter box. What other methods are available to open the windows desktop from the CentOS-6.5 host console or by remote access that allow me to have a re-sizable MS-Windows desktop display for this guest running on my normal (gnome2) desktop?

Any suggestions?
