qemu emulates a PCI device.

I would take an existing VNC client and modify it to log the "screeen activity" you want to log. VNC is a well-documented protocol, there are several high quality open source clients [gtk-vnc is the one I'd pick], and doing this means the guest can run at full speed. It depends a lot on how you define "screen activity". Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-top is 'top' for virtual machines.
