James, you may want to try out:

Spice client +
QXL drivers installed inside VM +
Spice Guest tools installed inside VM +
VM video driver set to 'qlx' +
configuring Windows 7 VM with Spice Display device

 From there, you'll be connecting to the VM console via the hypervisor: 
console displays are only exported on hypervisor localhost.

That way you should be getting the best user experience - smooth mouse 
control, guest resolution adapting to the client screen resolution/geometry.

Worked for me with both WindowsXP and CentOS 6.
