You could use spice under Fedora 14, but you'll have to configure qemu
directly. (-vga qxl).
-However-, the qxl driver for Windows 7 / x86_64 is unsigned, which
means you cannot use it under Windows 7 without disabling the driver
signature enforcement every-time you boot the guest (F8 during boot;
disable driver signature enforcement).
